Industrial wastewater treatment market prospects?

For industrial wastewater treatment, the strict standard, the strict regulatory system is very important, technology development is also very important, to make industrial enterprises have alternative technical solutions.
'twelfth five-year', and is related to development of technology, countries still need to treat industrial wastewater treatment from industrial structure adjustment and so on high.
first of all, the industrial structure adjustment and industry ( Product, production capacity) Obsolete. Adjustment of the object is high energy consumption, high material consumptions, high pollution and resource consumption industries, and small manufacturing enterprise. Such as: straw paper, coal, coke, dye, medicine, pesticide and other fine chemical industry, brewing, cassava starch, alcohol, lead and zinc smelting, circuit boards, foaming agent, ionic membrane caustic soda, etc. The industry waste water pollution treatment is difficult, high investment, high operation cost, to ban exports, when from to satisfy domestic demand, or even to rely on imports, strictly control the scale of quantity. Measures should be taken to strict environmental management system from the central government level, from the project examination and approval, the eia began restricting these industries.
second, improve the emission standards, promote the depth of governance. When standard, must adapt to processing technology, increase the technological process, key technology, improve the removal efficiency. At the same time, strengthen the recycling of industrial waste water, waste water recycling, deep processing and development of low emission technology, etc.
the third, and promote the development of clean production and circular economy.
4, improve the skill level of facilities operation and management. Wastewater treatment facilities is very important for the operation and management level, the construction of facilities and technology support of science and technology is important, but the root also support national standards and emission reduction is running. The adoption of advanced technology, defect reconstruction and ensure normal operation of all need the support of new and high science and technology, and the latter is more demanding.
'twelfth five-year' industrial wastewater pollution control key techniques include:
clean production technology ( Reform of the production process) Online, such as circuit board etching liquid circulation technology, surface treatment of plating solution circulating online technology, cleaning, and comprehensive utilization technology of pulping and papermaking.
the process control technology ( Strengthening pollutant emission control) : energy saving, water saving, save raw materials technology, comprehensive utilization of valuable material recycling and resource recovery technology, waste water recycling and regeneration recycling technology, etc. Such as cassava alcohol wastewater treatment technology route, beer wastewater treatment technology, etc.
end governance technology ( The key process) : 'chemical/biochemical' integrated composite processing technology ( Based on the biological membrane reactor and membrane bioreactor based on high technology of biological denitrification and phosphorus removal sewage treatment) ; Fine, high speed filtration separation technology and a new filter material and other high efficient solid-liquid separation technology and equipment; Efficient sludge digestion of low energy consumption and concentration, dehydration and drying and incineration technology and equipment; High strength, resistance to pollution of ultrafiltration, nanofiltration membrane hardware such as membrane material, membrane components and membrane group; Chemical catalytic oxidation/reduction techniques and efficient oxidant, the reductant, and high efficiency catalyst; Supercritical, acoustic catalytic and electrochemical catalysis, photocatalysis oxidation technology; Efficient anaerobic, moors of complete sets of equipment production and biogas purification and compression technology.
I'm sorry, '11th five-year plan' involved in industrial waste water in the water is not much, and the 'twelfth five-year' special water, industrial waste water treatment, almost no special research topic. From the perspective of industrial waste water, the national investment in technology research and development to strengthen more and more, companies need to be economically feasible, the effect is obvious solution.


in the aspect of industrial wastewater pollution control in our country have done a lot of work, pollution control technology, the industry of the manufacturing process of improving and let us see the hope of pollution control.
paper, MSG, pharmaceutical, chemical and so on are all wastewater is very difficult to conquer 'fortress', in these respects, researchers and government departments, manufacturing enterprises, environmental protection company to carry on the unremitting efforts.
the paper mill pollution has led to many ecological suffered severe damage, the development of the papermaking black liquor processing technology, and shut down and the use of a variety of means, turned it around.
in the organic acids production industry, including monosodium glutamate, lysine production of manufacturing process to increase the concentrate, mother liquor evaporation recycling fermentation, multi-effect evaporation, with these processes, the waste water would be easy to handle, or did not deal directly with the 'water'.
citric acid industry to develop a new extraction technology, the original calcium salt extraction crystallization, the crystallization of ways to use raw materials are acidic, after adding sulfuric acid discharged water to handle, great harm to the environment. Now switch to industrial ion chromatography, direct extraction, don't need to add sulfuric acid, recovery rate is raised, the final water treatment is also more easy.
all in all, the special industry in China to take a lot of targeted measures, at the same time the original emission standards are revised, such as the original starch waste water of the organic matter mainly concerns, now include ammonia, nitrogen up to standard.
