Problems solved by technology

At present, environmental protection has attracted the attention of the country, society and factories. However, the amount of wastewater mentioned above is large. The existing chemical wastewater treatment system has poor processing capacity, low wastewater treatment efficiency, and high treatment costs. Some small chemical factories chose to discharge untreated wastewater illegally and privately. After the wastewater entered the public water source, it caused serious impact and harm to the environment and human health and safety.

Abstract

The invention relates to an advanced treatment system for chemical wastewater. The advanced treatment system comprises an evaporation chamber, a stripping tank, an adsorption tower, an ammonia absorption tower, a first sedimentation tank, a reaction tank, a second sedimentation tank, an electrolytic tank, a sludge centralizing tank, a sludge conditioning tank, sludge dewatering equipment and a dry sludge storage bin. By the arrangement, the advanced treatment system has the advantages that advanced treatment of the chemical wastewater can be performed, the harmful substance contents of the treated wastewater are reduced to the maximum extent, the problem that treated wastewater still causes large pollution to the environments due to low treating degree is avoided, the steps can be performed orderly during wastewater treatment, waste heat is effectively utilized, and wastewater treatment cost can be lowered effectively.

Description

technical field [0001] The invention relates to the technical field of chemical wastewater treatment, in particular to a chemical wastewater advanced treatment system. Background technique [0002] Chemical wastewater refers to the wastewater generated during the entire production process of chemical production. Chemical wastewater is diverse, most of which are highly toxic, have a certain accumulation in organisms, and have obvious oxygen-consuming properties in water bodies, which can easily deteriorate water quality. ; With the rapid development of the chemical industry, the amount of waste water produced by it has increased rapidly, and the pollution of waste water has become increasingly widespread and serious. At present, environmental protection has attracted the attention of the country, society and factories. However, the amount of wastewater mentioned above is large. The existing chemical wastewater treatment system has poor processing capacity, low wastewater trea...
