Cutting fluid wastewater is often characterized by molecules that are difficult to break the oil-water envelope, high concentrations, and high COD.
Cutting fluid wastewater demulsifier (WD series) integrates demulsification, adsorption, flocculation and degradation, so that the oil or colloidal particles in the sewage lose their stable repulsion and attraction, lose stability and form flocs, which can not only completely break the emulsion, but also flocculate suspended solids to make the water clear. The front end is used with a demulsifier to remove most of the COD, total phosphorus, and other heavy metal ions

The main types of cutting fluid wastewater are oily wastewater from refineries in the petroleum industry, oily wastewater from oil washing tanks in railway locomotive depots, oily wastewater from oil freighters in shipbreaking yards, ballast water from oil tankers, tank washing water, emulsified oil wastewater from mechanical cutting processing, and oily wastewater discharged from the catering industry, food processing industry, and car washing industry.
The hazards of cutting fluid wastewater are mainly manifested in: oil substances float on the water surface, forming a thin film, which can prevent the oxygen in the air from dissolving in the water, reducing the dissolved oxygen in the water, causing the death of plankton and other species in the water body due to lack of oxygen, and also preventing the photosynthesis of aquatic plants, thereby affecting the self-purification of the water body, and even making the water quality smelly and destroying the utilization value of water resources. For fish, shrimp and shellfish to live in oily sewage for a long time will cause their meat to contain oil smell, and the taste is not suitable for consumption, in serious cases, due to the oil film on the gills of the fish and affect the respiration, resulting in suffocation and death, and the coalescing oil on the surface of the water body may burn and produce safety problems.
Therefore, oily effluent must be properly treated before it can be discharged.
Second, the treatment method of cutting fluid wastewater.
The fine oil beads are dispersed in the water to form a water-oil emulsion. Because the oil beads of the emulsion are extremely fine, a boundary film is formed on the surface with an electric charge, and an electric double layer is formed around the oil beads, so that the oil beads repel each other and are extremely difficult to approach. Therefore, in order to separate oil and water, the boundary film of the oil beads must first be broken, so that the oil beads are close to each other and gather into large droplets of oil, so as to float on the surface of the water, which is called demulsification.
Commonly used demulsification methods include high-voltage electric field method, pharmaceutical method, centrifugal method, ultrafiltration method, etc.

Steps: 1. The wastewater first flows to the flocculation sedimentation tank after passing through the grid and the screen, in order to make the treatment effect good, the coagulant is added to the flocculation sedimentation tank, so that the suspended solids in the wastewater treatment effect is better, and the coagulation dosing also plays a role in regulating the wastewater. The effluent after flocculation and sedimentation flows into the pre-aeration conditioning tank.
2. Air is introduced into the aeration conditioning tank to play the role of pre-aeration adjustment. The homogeneously regulated wastewater is pumped into a primary floating packing biochemical tank.
3. The aeration head with high oxygenation efficiency is installed in the biochemical tank and loaded with floating filler, which has proved that this technology has a high removal efficiency for COD and BOD. The wastewater in the primary floating filler biochemical tank flows into the secondary floating filler biochemical tank, and the method is the same in the second pool.
4. The water of the secondary floating packing biochemical tank flows into the inclined plate sedimentation tank. The addition of polypropylene honeycomb inclined pipe to the pool can greatly improve the settlement efficiency, in addition, the hydraulic load is high, the residence time is short, and the floor area is small.
5. The sludge precipitated by the coagulation sedimentation tank and the inclined plate sedimentation tank is discharged into the sludge thickening tank, and then dewatered by the sludge dewatering machinery.
6. The water discharged from the inclined plate sedimentation tank flows into the clear water tank and is discharged after testing.

BATA process principle.
Biological Methods (A O+MBBR):
Grille》 Primary Sedimentation Tank》 Conditioning Tank》 Anaerobic Tank》 Anoxic Tank 》 MBBR Aerobic Biochemistry " Secondary Sedimentation Tank "Qingzhao Bureau Eggplant Pool".
Among the traditional sewage treatment processes, the most common biological treatment process is the AO method, which has a high treatment efficiency for organic pollutants, but the treatment effect of phosphorus and nitrogen removal is not ideal. BATA strengthens the reflux of nitrified solution on the basis of traditional biological treatment, and uses reflux to accurately control the DO content in the anoxic section and strengthen the denitrification capacity of the processor. The mixture after intensified denitrification enters the anaerobic state, which increases the population of phosphorus-gathering bacteria and phosphorus absorption power, and realizes the efficient phosphorus removal capacity. The traditional aerobic nitrification section uses fixed hanging film filler, which is not ideal for increasing the content of activated sludge, BATA adopts the patented design of modified MBBR fluidized filler, uses the inner wall whirlwind structure to strengthen the biological implantation ability, greatly increases the microbial population, and through the fluidity of MBBR biological filler, increases the concentration of aerobic section and activated sludge, and enhances the efficiency of organic pollutants dewaxing and removal.

The raw water passes through the grid room - pump room - aeration grit tank - primary sedimentation tank - aeration tank - secondary sedimentation tank - chlorination room - Tonghui River.
Among them, the sludge produced by the primary sedimentation tank, aeration tank and secondary sedimentation tank is transported by car after passing through the sludge digestion tank, thickening tank and dewatering machine room.
The traditional activated sludge secondary treatment process is adopted: the primary treatment includes a grid, a pump room, an aeration grit tank and a rectangular advection sedimentation tank; The secondary treatment uses the air aeration activated sludge method. Sludge treatment adopts medium-temperature two-stage digestion technology, and the dehydrated mud cake is used as a fertilizer source for agriculture and greening after digestion.
Content expansion: The sewage treatment process is a combination of process methods used for a certain sewage treatment. Usually according to the quality and quantity of sewage, the economic value of the wastewater, the discharge standard and other social and economic conditions, after analysis and comparison, if necessary, it is also necessary to carry out experimental research to determine the treatment process to be adopted.
The general principles are: reform technology, reduce pollution, utilization, comprehensive prevention and control, advanced technology, economic reasonableness, etc. In the selection of processes, we should pay attention to the overall optimality, rather than just pursuing the optimality of a certain link.

NO1 water supply treatment method.
The task of water treatment is to improve the water quality of natural water sources through the necessary treatment processes to meet the water quality standards for domestic drinking water or industrial water.
From the perspective of water quality, the surface water sources mainly include rivers, lakes and reservoirs, and the turbidity of these water sources is generally high, and the degree of pollution is relatively heavy. Groundwater sources, the turbidity of the water is relatively low, the degree of pollution is relatively light, and some are not polluted.
From the perspective of different regions, the water quality is also very different, for example, some areas of groundwater contains iron, manganese, and some areas contain high fluorine.
From the user's point of view, residents' drinking water has high requirements for water quality, and industrial water has high requirements for water quality.
When surface water is used as the source of drinking water, the treatment process mainly includes dosing, coagulation, filtration, disinfection and other processes.
When groundwater is used as a source of drinking water, only disinfection steps are generally required to meet the water quality requirements. In recent years, groundwater and surface water have been polluted to varying degrees, and the conventional water supply treatment process often cannot meet the water quality requirements, so it is necessary to add activated carbon adsorption and other processes before the disinfection process to further remove pollutants in the water.
When the feed water is industrial water, the degree of treatment varies depending on the purpose. For example, if you use ground water, if the sand content is not high, the water can be produced after natural settlement. When recycling, add cooling equipment and take measures to reduce the water temperature.
However, when the sand content of the ground water is large, sedimentation treatment is required.
For special water, such as boiler water, softening, desalination and deoxygenation treatment are carried out on the basis of domestic drinking water, and then boiler water can be supplied.
NO2 wastewater treatment method.
The basic principle of wastewater treatment is to improve the production process, reduce the amount of wastewater, and reduce the load on the treatment structure. The second is to reuse wastewater to minimize the discharge of wastewater. The third is the most useful substance, the raw materials, semi-finished products and finished products in the production process are added to the first place, and the waste is turned into treasure.
Fourth, the wastewater should be properly treated so that some substances can be discharged harmlessly. Fifth, the selection of treatment technology and process should be advanced, easy to use, economical and reasonable.
There are many basic methods of wastewater treatment, which can be mainly divided into physical methods, chemical and physical chemistry, biological treatment methods, etc.
The physical method is to use physical action to separate suspended solids in water, and there is no chemical reaction in the treatment process. For example, precipitation.
Chemical and physicochemical methods mainly use chemical or physicochemical actions to decompose colloidal substances or dissolved substances in wastewater into harmless substances. For example, acid-base neutralization treatment.
The biological method is to use the action of microorganisms to convert organic matter in the water body into harmless substances. It is mainly divided into aerobic microbial and anaerobic microbial treatment methods.

The choice of wastewater treatment method mainly depends on the quality of the sewage
1) Physical methods (precipitation, air flotation, filtration, ion exchange, etc.);
2) Chemical methods (Fenton oxidation, acid-base neutralization, catalytic oxidation, etc.);
3) Biochemical methods (activated sludge method, biofilm method, oxidation pond, land treatment, etc.);
At present, most of the sewage treatment uses biochemical methods, and some of the more difficult ones are treated with physics or chemistry, or physicochemical and biological, and finally decide what method to use or what combination of methods is the element, or water quality.
The main pollutants of industrial wastewater (not called sewage) and domestic sewage include but are not limited to the following:
1. COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand): Consumption of oxygen in water leads to hypoxic death of organisms in water. The former is determined by chemical oxidation, and the latter is determined by dissolved oxygen in water consumed by microbial culture, which is generally calculated as 5 days.
2. Total nitrogen, ammonia nitrogen and total phosphorus: lead to eutrophication of water bodies, make aquatic plants and algae grow in large quantities, and consume oxygen in water bodies.
3. PH value: I know this.
4. SS (suspended solids): resulting in turbidity of the water body and large sediment content.
5. Chromaticity: Let the water change color.
The above pollutant indicators are the most concerned about sewage treatment, but they will be increased or emphasized differently according to the treatment goals and different types of sewage.
Sewage treatment mainly uses physical (filtration, sedimentation), chemical (chemical reaction) and biological (biological eating) methods to eliminate pollutants in the water.

Mine sewage.
There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods.
Sewage treatment plants: Some people have investigated more than 100 large treatment plants, and there are many serious problems, such as insufficient funds, high costs, low efficiency and other big problems, the general efficiency is less than 70%, and the low is only 40%.
Sewage treatment cost and energy consumption: basically high energy consumption and low efficiency.
In 2013, urban domestic sewage discharge has been the main source of urban water pollution in China, domestic sewage treatment is the top priority of urban water conservation and urban water environmental protection at present and in the future, which requires us to treat the construction of domestic sewage facilities as an important part of urban infrastructure to grasp, and it is an urgent thing.
With the development of science and technology, the direct utilization of sewage has become possible, and the use of sewage source heat pump system to utilize urban primary sewage.
The so-called primary sewage is the direct discharge of untreated domestic and industrial wastewater in the city, and the current utilization method is that the primary sewage directly enters the sewage source heat pump system for heat exchange, and consumes a small amount of electricity for indoor cooling and heating of urban buildings. There are several technical difficulties to overcome in wastewater reuse: clogging, corrosion, heat transfer efficiency.
The sewage source heat pump system is composed of two parts: sewage heat exchanger and sewage source heat pump. After the urban primary sewage directly enters the sewage heat exchanger for heat exchange, the heat exchanged is transferred to the room by the heat pump inside the sewage source heat pump.
The advantages of reusing urban raw sewage are: energy saving, environmental protection, and no pollution.
The robbing mobility is good, the ultimate is not weak, and it is also a cut of people, q long-range, and it can also be consumed.
