Guide to Buy Industrial Wastewater Treatment Plant in Lvyuan Water Purification Equipment

For electroplating wastewater contains a lot of metal ions, especially nickel ion, copper ion, such as direct emissions has serious pollution on the surface water, water discharge place is nothing grows, Shanghai chemical industrial park, there are several electroplating factory, before delivery after ion exchange treatment, waste water or up to the mark, so several for centralized processing again, although the traffic is not big, but the effect is very big.


I company for the design of dosing capture + filtration system + ion exchanger + ultrafiltration + reverse osmosis water system, dosing mainly metal to metal ions to capture capture agent, preliminary to remove the nickel ion in the water, and then through the quartz sand filter, activated carbon filter adsorption belongs to the basic mechanical filter processing, but greatly reduces the metal ion content, then in addition to the nickel ion exchanger for further adsorption, nickel ions is basically good, and then after ultrafiltration and reverse osmosis treatment, basic no nickel ion, can be used to mark again.

Of ultrafiltration and reverse osmosis water collected from the pool, after filter, the water treatment, waste water again after the system pressure filtration of solid waste to the qualified solid waste disposal unit for processing, is a system to do big zero emissions.


the water processing system run down, everything is normal, solve the enterprise operation.

1, what is the distinguishing feature of surface water quality?


surface water salinity and hardness is generally low, the salt content is in commonly 70 a 900 mg/L;

0 tendency/L.

The water quality of surface water is not stable, larger changes with the seasons.

Spring winter two season, water, salt content, high hardness, and low turbidity.

Altogether, due to the effect of precipitation, salt content, hardness decreased, and the turbidity is rising sharply.


2. What is the distinguishing feature of groundwater quality?


is precipitation after soil and formation of groundwater seepage flow, or so the dissolved more salt.

Salt in 100 ~ 500 mg/L, hardness in 2 lOmm0l/L, little suspended solids and turbidity is low.


groundwater quality in general is stable, seasonal variation is not very big influence on the quality.


3, industrial production have any requirements on water quality?


all kinds of industrial water, according to the used methods can be divided into two categories: direct and indirect in the use of water.

Direct water, water, direct contact with product quality of our products have very big ring, so the requirement of good quality;

Indirect water, generally have no effect on the quality of product, for anticorrosion and antiscaling different requirements, the need to adopt different water quality.

(
1)

Raw materials in the use of water is directly used as raw materials or as part of the raw material and using water.

In the beverage, food processing industry, had a greater influence on the water quality of product, the best water should be colorless, tasteless, no turbidity, salt content is appropriate, ammonia, nitrogen, nitrite, bacteria and other indicators meet production requirement.


synthetic fiber, such as electrolysis, medical demands high quality of pure water.

(
2)

Product processing water refers to in the process of production is used for washing, bleaching, beating and so on, it also calls for better water quality.
The water quality requirement is roughly the same as the raw materials with water.


electronic industrial water demands high quality of pure water, etc.

(
3)

Boiler water due to the high hardness of water can make the scale, the boiler thermal efficiency is lower;

Dissolved oxygen and salts can cause corrosion of boilers and piping;

Soda azeotropic HSiOf and alkalinity causes, and influence quality of steam.


as a result, the boiler for water hardness, salinity, alkalinity, pH value, HSiOf and dissolved oxygen have strict index requirements.

(

The function of cooling water for cooling water is cooling medium heat, so to prevent the corrosion, fouling and microbiological hazards are three major tasks of the cooling water processing.

Water quality of cooling water, therefore, the hardness, suspended solids, dissolved gas, oil and other organic matters, such as algae and microbial should be strictly controlled.

Printing and dyeing wastewater treatment technology more coupling
printing and dyeing wastewater treatment with water, complex, high organic matter content, water quality and biological sex difference, alkalinity, high chromaticity, etc.

Environmental science research institute of jiangsu province hai-suo wu according to the characteristics of the dyeing and printing wastewater and the treatment process is put forward, the research focus in the printing and dyeing wastewater treatment technology at present can be divided into the following four parts: the pretreatment stage by pH control, homogeneous average to reduce the impact load, biological toxicity;

By anaerobic biological stage of processing facilities improve, aerobic microorganism raise to biological sex;

Deep processing stages through adsorption separation, filtering, oxidation technology meet standards;

Regeneration recycling processing phase coupling regeneration technology by membrane separation, purification and recycling.

And points out the development trend of printing and dyeing wastewater treatment technology is efficient biological coupling, adsorption, separation technology, production process and waste water treatment of the coupling, high quality development and printing and dyeing wastewater reuse technology of desalting and regeneration.


the polluting industries of moderate sewage treatment and reuse is an important means of reducing investment and operation cost, so the choice of economic efficient pretreatment process optimization is the focus of the research in recent years, in the process of a new round of sewage treatment plant to standard transformation, deep processing standards process will be more widely used.


new industry printing and dyeing wastewater treatment methods

in the production of 222 joint degreased cotton winding water filter effectively remove impurities of large amount of high filtration efficiency, etc

Water quality is good or bad a direct impact on people's physical health.

So find a effective equipment to improve water quality problem is the problem that people are very concerned about.
Filter is mainly used for water filtration filter industry, etc.

The normal work of the protection equipment or clean air, and when the fluid is placed into a certain size of mesh filter, remove a small amount of solid particles in the liquid, the impurity is blocked, and clean flow through the filter out.


filter can remove water, suspended solids, particulate matter, reduce the turbidity, purify water quality, reduce system dirt, bacteria and algae, corrosion, etc, to purify the water quality and protect the system precision equipment of other equipment to work normally.


depending on the different raw materials, the service life of filter element will be different.

Longer duration of use, can jam the impurities in the water filter, activated carbon filter adsorption saturation.

So, in general, PP filter 3 months need to change, and activated carbon filter 6 months need to change.

And hollow fiber due to not clean, is usually placed in the back-end of the PP cotton and activated carbon is used, otherwise easy to jam, used as a water purification equipment at the end of aseptic is 1
2 years need to be replaced.
10 - ceramic filter can generally be used
12 months, good ceramic filter can use 3 -
Five years, or even more time.


straight drinking water filter maintenance and maintenance
1.

The hydraulic oil filter is the core part of the filter, filter is made of special material, belong to wearing parts, need special protection and maintenance.

　　2.

When the filter in the system work after a period of time, the hydraulic oil filter filter pollution has intercepted a certain amount of impurities, then pressure increases, the flow will decrease gradually, transmission device will remind alarm, then need to clear in time the impurities inside the filter, clean the filter.

　　3.

In the process of cleaning filter, we must pay attention to the hydraulic oil filter deformation or damage is not allowed.

Otherwise, cannot be used again, lest affect filtration efficiency, so as to bring the entire system damage.
