Environmental protection market & throughout;

To break the bottleneck of tradable permits
to break & other;
First pollution, then governance & throughout;

The traditional environmental protection path, in promoting the ecological environment governance, in addition to the use of administrative power, must with the aid of substantive breakthrough in the market mechanism.

Recently learned in hunan, hubei, province through exploring to establish environmental liability insurance, river basin ecological compensation measures, such as chemical oxygen demand and sulfur dioxide in overfulfilled countries & other;
11th five-year plan & throughout;
After reduction, keep falling.

The future need to breakthrough in the field of emissions trading, can truly establish & other;

The government leading, market, enterprise participation throughout & advanced;
The environmental protection mechanisms.


to benefit compensation mechanism to improve the environmental management level
at present, our country has already entered a period of pollution accidents, some of the pollution accident has been a serious threat to people health and social stability.
In order to break & other;

Enterprise pollution, victims, the government took responsibility for people, the whole society pay & throughout;

Cycle of hunan province in the construction of two type society pushing environmental pollution liability insurance system.


the introduction of environmental pollution liability insurance, the market share in the enterprise, the government's environmental risk, safeguard the rights and interests of the public further, also for the enterprise and the government provides the power of the pollution treatment.


in changsha city environmental protection bureau also released the first domestic environmental risk management measures, for the first time to define environmental risk enterprise, for environmental risk of grade 1 and 2, enterprises shall purchase liability insurance of environmental risks, three kinds of enterprises are discretionary purchases.

As of October 2010, the province has 279 (
Times)
The environmental pollution liability insurance companies covered.


to promote & other;
Green insurance & throughout;

System, set up 4 million yuan a year in wuhan city special financial subsidies to insurance companies.

For high premium subsidies for high-tech enterprises, in the past two years the premium subsidies are in more than 70% of the premium.

At present, the accumulative amount of the insurance companies more than $100 million.


in the middle and lower reaches of interests are not consistent, the environmental protection enthusiasm is not high, has always been a difficulty of river basin pollution control.

Hunan province in xiangjiang river basin management, comprehensive linkage mechanism in the basin, on the basis of trial conducted in xiangjiang river basin ecological compensation.

Worked out the measures for the implementation of the xiangjiang river basin ecological compensation, 51 cities and counties within the basin pilot implementation of provincial financial ecological compensation, gradually establish & other;

Compensation for the downstream to upstream water conservation & throughout;
“

Upstream to downstream excessive pollution or environmental liability accident compensate & throughout;
The bidirectional responsibility mechanism.


manage pollution emissions trading mechanism has new
in recent years, hunan, hubei, at the same time of using administrative measures on environmental management, and fully using market forces, promote the paid use of environmental resources, on the one hand, increased government pollution sources of funding, strengthen the motive force for enterprise voluntary emissions on the other hand, to promote its real become the subject of pollution.


in order to define the emission, hubei, in October 2008 by the national and provincial environmental protection department for examination and approval after the construction of the project, the new conditional distribution of pollutant emissions.

Companies if excess emissions, need to buy emission index, if through cleaner production and pollution control to reduce pollution, transferable savings emissions targets for market returns, also can reserve itself.


emissions trading remained three problems
at present, for the two provinces with emissions trading as an opportunity to further accelerate the establishment & other;

The government leading, market, enterprise participation throughout & advanced;
The environmental protection mechanisms.

But the experts say, the comprehensive promotion rolled out emissions trading, still need to solve the three difficult problems.


a and the transferee main area is lesser, caused the unfair between enterprises.

The revised measures for the main pollutant emissions trading in hubei province to assignee of tradable permits to municipal environmental protection departments above is responsible for the examination and approval of environmental impact assessment documents & other;
New, change and expansion & throughout;
Construction project, but the county (
City)
Approval of the project is still not.

Many projects in the same industrial park, approval levels of different direct impact on emissions trading, some enterprises feel & other;
Injustice & throughout;
。


2, the current unit price bidding models easy to cause unfair.

The English auction bidder is only considered in use auction bid, without regard to order emission quantity required, which leads to the buyers often doesn't care about the price of small demand, resulting in abnormal prices to rise.

Advice as emissions trading is active, can consider to adopt various auction methods accord with the characteristics of the subject matter.


3, caused by the environmental protection department giving permits easy social question.

Early pilot emissions trading emissions cuts in the transfer of credit is to reward form the buyback by the government, through the elimination of backward production capacity to produce emission reductions, the environmental protection department on behalf of the government.

But played by department of environmental protection shall be for a long time, easy cause social purpose for the government to carry out the pilot emissions trading, affect the government's credibility.

In the mid-1970s, Calanese developed a new method for preparing microporous membranes, and launched a commercial product of celgrad polypropylene microporous membranes. This method is generally aimed at crystalline polymers. Word. First, a highly oriented crystalline polymer is prepared, and then at a temperature close to the melting point of the polymer, it is extruded into a film with rapid stretching. After the film is cooled, the film is stretched a second time to make the crystal structure of the film. It is damaged, resulting in (200-2500)*10-10m cracks, thereby forming a microfiltration membrane. The basic method of stretching is to extrude the membrane or fiber at a relatively low melting temperature and high stress, and then at a slightly lower Heat treatment at the melting point temperature, the chain segments can move to make the crystal larger and harder, and the polymer chains are folded on the crystallized surface without melting together to eventually form the desired film. This method is suitable for thermoplastic materials such as polypropylene, polyethylene, and polytetrafluoroethylene. The obtained microfiltration membrane has a high porosity, up to 90%, and the pores are elongated and the pore size ranges from 0.1 to 3um. , and the pore structure is a fine-slit network pore structure. Example Polypropylene microporous stretched film material PP solvent No film-making process Polypropylene resin-melt extrusion-hollow forming-cooling-winding-heat treatment-stretching-heat-setting-finished polypropylene hollow fiber membrane. Example Preparation of PET fiber film material by stretching method PET flux Trifluoroacetic acid, dichloromethane. Film making process The film making process includes the following aspects. a Spinning Dissolve the dried ultra-high molecular weight PET sample with a mixed solvent of trifluoroacetic acid/dichloromethane (volume ratio of 7:3) for about 3 days at room temperature, and pour the spinning dope into the prepared spinning solution. In the tube, water is used as coagulant, and dry and wet spinning is carried out at room temperature. The temperature is low, the orientation temperature of the drawn yarn is high, and the crystallization is low. This structure is beneficial to the subsequent secondary drawing, and then the secondary drawing is carried out at a temperature of 230 degrees. Crystallization, therefore, the temperature of the secondary drawing is required to be higher than the crystalline melting temperature of PET to melt the original crystal region, so as to realize the rearrangement of the fiber structure. C. Heat treatment With ethylene glycol as the heat medium, the treatment time is 3min. Appropriate heat treatment can improve the structure of the fiber and improve the thermal properties of the fiber. The heat treatment time has the greatest impact on its mechanical properties, and the performance decreases with time.
