Abstract

The invention discloses an industrial wastewater treatment system, comprising a coarse screen, a fine screen, a regulating reservoir, a grit chamber, a primary settling tank, an anoxic pool, an anaerobic pool, an aerobic pool, a secondary sedimentation tank, a coagulating sedimentation tank, a filter tank, a disinfecting tank, an air storage tank and a sludge storage tank. Compared with the prior art, the treatment system has the advantages that the pollutant removal capacity is significantly improved, the COD removal rate can reach over 98%, the SS removal reach can reach over 99%, and the chroma removing rate can reach over 98%. The system reaction only relates to biochemical reaction; a composite flocculant prepared from aluminum residue and coal ashes is added at the treatment stage; and all by-products such as hydrogen sulfide and methane generated in the production process of the system are recycled.

Description

technical field [0001] The invention relates to a treatment system for industrial waste water, which belongs to the field of water treatment in environmental protection. Background technique [0002] Industrial wastewater refers to the wastewater, sewage and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants produced in the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. [0003] Industrial wastewater is usually classified into the following three categories: [0004] The first is to classify according to the chemical properties of the main pollutants contained in industrial wastewater. Inorganic wastewater mainly contains inorganic pollutants, and org...
