Pig plant breeding sewage treatment project
The sewage of the pig factory mainly includes pig urine, part of pig manure and washing water of pig house, which belongs to high concentration organic sewage, and the content of suspended solids and ammonia nitrogen is large. After this untreated sewage enters the natural water body, the content of suspended solids, organic matter and microorganisms in the water increases, changes the physical, chemical and biological community composition of the water body, and deteriorates the water quality. Sewage also contains a large number of pathogenic microorganisms will spread through water or through aquatic animals and plants, endangering human and animal health. Therefore, the sewage treatment system of this project adopts the process flow of solid-liquid separation pretreatment anaerobic treatment aerobic treatment advanced treatment.

Spraying sewage treatment works
Spraying wastewater mainly comes from pre-degreasing, degreasing, surface conditioning, phosphating, passivation and other car body pretreatment processes. Cathodic electrophoresis process and intermediate coating and topcoat spraying process, automobile coating water contains resin, surfactant, heavy metal ions, pigments and other pollutants, especially the electrophoresis wastewater and painting wastewater have complex components, high concentration and poor biodegradability. Coating wastewater treatment mainly adopts the process of separation treatment, coagulation sedimentation, coagulation air flotation, sand filtration and so on.

Pickling sewage treatment works
Pickling process is an essential process for galvanizing, electroplating, metal products, machinery manufacturing, steel, metal materials and other industries. Pickling wastewater usually includes: deoiling (grease) wastewater; hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, phosphoric acid and other monoacid or several mixed acid wastewater; flushing wastewater and purification wastewater. According to different products, enterprises in various industries add chemical additives and other auxiliary materials in the degreasing and phosphoric acid purification process. Local environmental protection bureaus formulate different discharge standards for different types of enterprises according to the functional zoning of local waters. In the same region, different industries have different emission substances and emission standards. Pickling enterprises must formulate treatment modes and specific contents according to the emission standards.
Bean products wastewater treatment project
Sichuan Food Co., Ltd. is a large-scale agricultural product deep processing base integrating food research and development, production and sales. Its main products include soy milk powder and oatmeal. The production wastewater mainly comes from the soybean milk powder production process of soaking bean hot bean wastewater, syrup workshop generated cleaning wastewater, etc., its characteristics are organic matter (protein, starch, sugar) content is high, easy to corrupt, but not harmful substances, easy to degrade, etc., the wastewater is weakly acidic. The UASB reactor has the characteristics of more biomass in the sludge bed, high volume load, high removal rate and stable water quality.

Chemical wastewater treatment engineering
The basic characteristics of chemical wastewater are:(1) the water quality composition is complex, there are many by-products, and the reaction raw materials are often solvents or compounds with ring structure, which increases the difficulty of wastewater treatment;(2) the content of pollutants in wastewater is high, which is caused by incomplete reaction of raw materials and a large number of solvent media used in raw materials or production entering the wastewater system;(3) there are many toxic and harmful substances, many organic pollutants in fine chemical wastewater are toxic and harmful to microorganisms, such as halogen compounds, nitro compounds, dispersants or surfactants with bactericidal effect, etc.;(4) there are many biodegradable substances, low B/C ratio and poor biodegradability;(5) high chroma of wastewater. If it is not treated or not treated immediately discharged into water or used for irrigation, it will pollute the environment and affect people's health.

Medical sewage treatment works
The quality of hospital sewage is similar to domestic sewage, but the composition is complex. Such as disinfectants, heavy metals, organic reagents, and possible radioactive isotopes from various departments such as laboratory tests, inspections, and surgeries. As a hospital, its sewage contains a large number of toxic chemicals and a variety of pathogenic bacteria, viruses and parasitic eggs. They have certain adaptability in the environment, and some even survive for a long time in sewage. If they are not treated or not treated immediately discharged into water or used for irrigation, they will pollute the environment and affect people's health.
