Technical Field

Background

The filter is an important ring in the filtering equipment and is also an indispensable device on a medium conveying pipeline, and the filter consists of a shell, a filter element, a pollution discharge part, a transmission device and an electric control part. The filter is widely used in the fields of metallurgy, chemical industry, petroleum, paper making, medicine, food, mining, electric power and urban water supply. Such as domestic clean water, industrial waste water, filtration of circulating water, regeneration of emulsion, filtration treatment of waste oil, continuous casting water systems and blast furnace water systems in the metallurgical industry, and high-pressure water dephosphorization systems for hot rolling. The treatment of high organic wastewater in the modern environmental protection process is a key and difficult problem in the environmental protection industry, and firstly, the concentration of organic matters is high. High concentration organic waste water (high organic waste water for short), wherein COD (chemical oxygen demand) is generally more than 2000 mg/L, some COD is even as high as tens of thousands or even hundreds of thousands mg/L, relatively speaking, BOD is lower, and the ratio of BOD to COD of a lot of waste water is less than 0.3. Secondly, the components are complex. The organic matters in the waste water containing toxic substances are aromatic compounds and heterocyclic compounds, and also contain sulfides, nitrides, heavy metals and toxic organic matters.
