How aluminium chloride treats plastic factory wastewater

Poly aluminium chloride is a wide range of water purification chemicals, many factories have to be used, poly aluminium chloride has the characteristics of fast settling speed and cheap price, so many people like to use poly aluminium chloride to purify water. There are many production methods of polyaluminium chloride, there are different production processes such as drum, plate and frame, spray, etc. The content of polyaluminium chloride is also various, we can choose different content of polyaluminium chloride when dealing with different types of sewage. Today, Henan Xinhuan polyaluminium chloride manufacturer will explain to you how polyaluminium chloride treats plastic factory wastewater? First, the source and characteristics of plastic washing sewage Plastic is an important raw material in our production and life, plastic products can be seen everywhere in our life, it can be said that more and more important, the dosage is also increasing. Plastic waste is a recyclable resource, in the recycling process mainly through the plastic cleaning, separation and wet crushing process, made of plastic particles reuse. In the plastic cleaning process will produce a large amount of wastewater, wastewater mainly contains sediment, and other impurities attached to the surface of the plastic. The concentration of pollutants in the wastewater is closely related to the nature of the waste plastics used. If it is discharged directly without treatment, it will cause pollution to the environment and waste of water. Plastic washing wastewater has the following characteristics: 1, containing organic pollutants; 2, containing grease pollutants; 3, containing suspended pollutants; 4, PH value pollution. Second, poly aluminium chloride treatment process of plastic washing sewage is as follows: 1, plastic washing sewage collected by the collection network, automatic flow into the grating canal, and then by the fine grating to remove large suspended solids in the water, and then flow into the regulator, can be adjusted in the regulator to regulate the amount of water and homogenisation of water quality; 2, the choice of coagulation and precipitation, generally choose to add polyaluminium chloride in the regulating pool. Adjustment pool is equipped with sewage lifting pumps and level controllers, when the water level reaches the limit by the pump will be lifting sewage into the air flotation and sedimentation machine. In the system, the suspended matter in the water is adhered by tiny bubbles to float to the surface of the water, and the suspended matter will be scraped to the sludge tank by the slag scraping equipment to remove the suspended organic matter; 3, the choice of poly aluminium chloride coagulation and precipitation method, after treatment of plastic washing sewage. Through mechanical filtration, treatment to remove most of the suspended solids in the sewage, than the significant organic matter will slowly slide along the inclined tube filler to the bottom of the equipment, through the sludge valve discharged to the sludge tank; 4, the supernatant disposed of by the equipment flows into the buffer pool, in the buffer pool to regulate the amount of water and homogenisation of water quality, and then by the sewage lifting pump up to the multi-media filter, through the filtration and adsorption of activated carbon to remove the remaining pollutants in the water, air flotation pool scum and sludge pipe sedimentation sludge discharged into the sludge storage tank, the timing of external transport and disposal of purified sewage discharged to meet the standards; 5、The effluent discharged up to the standard is reused in the production process, which can achieve the purpose of reducing the amount of effluent discharged and reusing the wastewater.
