Abstract

The invention particularly relates to a sewage purification treatment system. The sewage purification treatment system comprises a sewage tank, a first filtration component, a settling tank, a secondfiltration component and a metal ion enrichment component, which are sequentially communicated in series through stainless steel pipes; the metal ion enrichment component comprises a cylinder, a filler and an outlet three-way valve, and the cylinder is fixedly filled with the filler, namely chitosan; a cleaning connector is arranged at the top end of the cylinder; the outlet three-way valve is connected to the bottom end of the cylinder, a first opening of the outlet three-way valve is communicated with the cylinder, a second opening thereof is a purified water outlet, and a third opening thereof is a cleaning liquid outlet. The sewage purification treatment system has the advantages that the filtration components are used to intercept solid particle impurities, flocculants are added to the settling tank to remove part of the impurities, heavy metal ions are removed by adsorption, and accordingly, the effect is excellent due to combination of the three purification modes; the metal ionenrichment component has a better adsorption effect than ion exchange resin as the chitosan serves as the filler, reversible adsorption is achieved, and accordingly, the heavy metal ions can be recycled to avoid secondary pollution.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage purification treatment system. Background technique [0002] In recent years, the rapid development of industry has brought high economic benefits to people, but the high cost of industrial wastewater treatment has caused a large amount of industrial wastewater to be directly discharged into rivers, resulting in river pollution. Among them, industrial wastewater such as electrolysis, electroplating, pesticides, pigments, and paints contains a large amount of heavy metal ions, and there are many types of heavy metal ions, which brings certain difficulties to the treatment. The environmental pollution of wastewater containing heavy metal ions has the following characteristics: ①Heavy metal pollutants cannot be decomposed into harmless substances in the natural environment, but can only change in form or transfer between different phases. During the process, its...
