How to deal with cosmetics production wastewater?

Demulsification flocculant can be used for pretreatment, because this kind of wastewater is difficult to meet the biochemical standard, and it needs to be pretreated for demulsification and then biochemical to achieve the most ideal effect.

Use demulsifiers with biochemical processes.

Cosmetics production wastewater contains a large amount of surfactants and organic oils, so the treatment of this kind of wastewater is actually to remove the oil and moisture. As the name suggests, the demulsifier is to break the original water-oil wrapping form and achieve oil-water separation. Among them, Fanqing cosmetics wastewater demulsifier can reduce the color and COD in wastewater on the basis of ensuring the separation of oil and water.

It is easy to operate and low cost.

Wastewater is mainly cleaning and flushing wastewater, such as washing water in the refining process of products or intermediate products, washing water for reaction equipment or reactor when replacing products or intermittent reactions, washing bottle water, etc. The main components are raw materials, products, and intermediate products and by-products. Second, the wastewater formed in the process of product processing and production process such as distillation residue, crystalline mother liquor, filter mother liquor and other wastewater.

The alcohol solvent used in perfume cosmetics is discharged when it is filtered with potassium permanganate, hydrogen peroxide, activated carbon filtration, and fragrance.

You can choose the sewage treatment process and sludge treatment process, the sewage treatment process is composed of biochemical treatment + physical and chemical treatment part; The sludge treatment process consists of the sludge treatment part discharged from the sedimentation tank.

Demulsifiers can be used, and the main principle of demulsifiers is to separate the emulsified oil from water. It has a very strong chemical affinity for water and can encapsulate water molecules in oil, oil or dirt. A microfilm is formed around the water molecules, which changes their surface tension, resulting in rapid, complete stratification that rapidly separates them from the sediment at the bottom while degrading the COD in the water.

Cosmetics destruction and disposal process browsing, as long as it is ordinary waste goods and products can be destroyed.

1. The process of destroying cosmetics, the following issues need to be considered before the scrapping and scrapping of cosmetics:

1. What is the reason for the scrapped products, which need to be scrapped or destroyed.

2. Whether the financial write-off department is involved after the cosmetics are scrapped.

11. Whether it is necessary to provide resident collection and pretreatment service specialists.

We can see counters in many supermarkets and shopping malls to buy cosmetics, and the wide variety of brands and types often makes people not know how to choose. What we don't know is that cosmetics production processes use a lot of water, and at the same time, a lot of wastewater is discharged, which is extremely complex. This requires the use of wastewater treatment equipment for cosmetics production, and this article will focus on wastewater treatment technology.

Coagulation and sedimentation process of cosmetics production wastewater treatment technology.

From the above, we can understand that the composition of cosmetics production wastewater is extremely complex, and it is quite difficult to treat it, so it is necessary to adopt the most suitable method that will not cause secondary pollution. Coagulation and sedimentation process of cosmetics production wastewater treatment equipment, coagulation and sedimentation stage removes a large amount of SS, LAS and some organic matter. The coagulant is added to the regulating tank, and the colloidal impurities in the water are adsorbed and bonded to form larger particle flocs.

The floc settles through the inclined pipe to form sludge, which is discharged from the sludge discharge pipe and the effluent can be clarified.

Cosmetics production wastewater treatment technology, biological contact oxidation.

In addition to the coagulation process, the wastewater treatment equipment for cosmetics production can also use the traditional biological contact oxidation method. This method can effectively save economic costs, has strong biological activity and stable operation. It is mainly the bottom-up contact of wastewater with biofilm-covered fillers, under the action of which organic pollutants are converted into carbon dioxide and water.

Generally, the wastewater of cosmetics wastewater mainly contains glycerin, fatty acids and other substances, which have good biodegradability and can be directly treated by biological treatment.

When the COD of the influent water is high, the coagulation process can be added to remove some chemicals with large molecular weight, and then enter the biochemical treatment unit.

The biochemical processes commonly used are anaerobic and aerobic. For different influent concentrations, the processes required to be designed are also different.

Cosmetic wastewater needs to be demulsified and decolorized first, and the refractory and toxic pollutants are removed, and then discharged through the biochemical system. Chemical flocculation is generally used for demulsification and decolorization in the pretreatment, and it is recommended to use Shanmei Environmental Demulsifier or Decolorizer, which can effectively remove various pollutants.

Treated with demulsifiers. Process flow: first add 5 parts per thousand of the demulsifier (adjust it according to the specific wastewater concentration), then adjust the pH value of 7-8, and finally add PAM (polyacrylamide) precipitation to fully stir in the coagulation primary sedimentation tank.

The treated water has no impact even if it is biochemical, it can be discharged up to the standard, and it can also be recycled.

Cosmetic wastewater must be treated before it can be discharged. You want to tell me what substances are in the wastewater, and how much they contain. and standards for discharged after treatment.

I can give you an accurate solution. No data is nonsense. Hope my reply can help you.

Cosmetic wastewater generally comes from workshop reactors, containers, storage barrel cleaning wastewater and process discharge wastewater in the production process of products, etc., its main characteristics are that it contains a large number of anionic surfactants, oils, alcohols, thickeners, antioxidants and other macromolecular colloidal substances, as well as some calcium and magnesium ion chelators. Due to its complex composition, high concentration of organic matter, and high COD value, the effect will not be ideal if the treatment plan is the same as that of general wastewater. Therefore, it is recommended to use Fanqing's special cosmetics wastewater demulsifier to treat, so that the characteristics of cosmetics wastewater research and development are still very good.

In the pretreatment process, it can be demulsified first, because this wastewater contains a large amount of surfactants or vegetable oils, so it is necessary to separate oil and water first, make the water clear, and then carry out biochemical treatment.

For cosmetic wastewater, it is necessary to use a demulsification decolorizer to remove surfactants and emulsified oils. Biochemistry can only be carried out by removing more than 95% of COD from wastewater.

Sludge treatment is an important part of the wastewater treatment process.

The sludge produced by domestic sewage treatment is generally composed of relatively loose small pieces of matter, with high moisture content, and the sludge volume can reach dozens of times of the solid volume it contains, and the sludge contains a large number of organic matter and harmful substances, and may contain dangerous pathogenic bacteria, parasite eggs, etc. In addition, the nature of sludge is very unstable and easy to decay, causing secondary pollution, so it needs to be treated in time to reduce the amount of putrid substances containing pathogenic bacteria and emitting odor and decompose.

The sludge produced in the hydrolysis tank is relatively stable and has good sedimentation performance. For sludge treatment in urban residential areas, manure pumping trucks can be called to clean it regularly and transport it to landfill.

For the chemical sediment produced in the pre-treatment of production wastewater, special sludge treatment facilities need to be set up to treat it, because the main component of sludge produced in production wastewater treatment is calcium phosphate, which can be used as phosphate fertilizer. Odor & Noise Control.

The odor of the wastewater treatment station is objective, and it is important for the process designer to keep the wastewater in the aerobic structure free of local anaerobic; In the early stage of enterprise production, the residence time of the acidification hydrolysis tank may increase due to the small amount of wastewater discharge, and the process will automatically change from acidification to anaerobic biogas, which can be used or burned according to the requirements. In terms of management, immediate treatment of salvaged solid waste is an important means to eliminate odors.

For most of the wastewater that is not suitable for direct biochemical discharge, the first thing to do is to pre-treat, only after pretreatment of wastewater can other processes, the same is true for cosmetic wastewater, you can first demulsify treatment and then pass through the biochemical system, for the concentration of low concentration of wastewater demulsifier addition is generally less.

There will be a special treatment method for sewage purification.

It is recommended to use the AO+ biofilm separation process. The removal rate of ammonia nitrogen in the AO process is 80%, but that is a theoretical value and it is difficult to achieve, but with the addition of a biofilm separation process, this blind sample removal process should be able to reach more than 95%. Do dermabrasion to stabilize the discharge up to the standard.

You can go to the environmental protection to ask questions about the treatment of wastewater, I hope it will be helpful to you. Microelectrolysis + Fenton + blow-off +a indicates that the sludge activity is low, which may be due to the high toxic and harmful substances in the wastewater, the high refractory COD, and the poor biodegradability. Wastewater treatment problems can be communicated to the environmental protection link, and a pretreatment can be added at the front end to reduce toxic and harmful substances as much as possible and further improve the biochemistry of sewage; Or add physicochemical treatment after biochemistry to remove COD through chemical methods to ensure that the effluent is stable and up to the standard.

Chemical wastewater refers to the wastewater produced in the process of producing products in chemical plants, such as the oily wastewater produced in the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank farms, air separation air compressor stations and other devices. Since the impurities in the water are mainly suspended particles and fine hair fibers, the impurities are removed by using the principle of mechanical filtration and microporous filtration technology. The working condition of the filter equipment is controlled by PLC or time relay to realize automatic backwashing, automatic wild wax operation, and the water pump provides the required water head of the filter, and the water outlet is directly introduced into the production system.
