3,4-dichloroaniline wastewater treatment system

Abstract

The invention discloses a 3,4-dichloroaniline wastewater treatment system. The system is characterized by comprising an adjusting tank, a precision filtering device, a resin adsorption device, a reaction treatment area sludge treatment device, an aeration device, a dosing device and a control device, the precision filtering device is positioned on the right of the adjusting tank; the resin adsorption device is positioned on the right of the precision filtering device; wherein the reaction treatment area is located on the right side of the resin adsorption device, the sludge treatment device islocated on the right side of the reaction treatment area, the dosing device and the control device are located on the outer side of the reaction treatment area, the aeration device is installed on the inner side of the reaction treatment area, and the reaction treatment area comprises a micro-electrolysis area, a Fenton oxidation area and a coagulative precipitation area. The system is stable inoperation, low in use cost and convenient to manage, 3,4-dichloroaniline in the wastewater can be recycled through the resin adsorption device, the raw material loss is reduced, organic matter in thewastewater is treated through microelectrolysis and a Fenton oxidation reaction, the treatment effect is good, the effluent quality reaches the standard, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of wastewater treatment systems, in particular to a 3,4-dichloroaniline wastewater treatment system. Background technique [0002] 3,4-Dichloroaniline is a colorless transparent liquid with certain toxicity. It is often used in the production of aniline, pesticides, phenol and chloronitrobenzene, and can also be used in the manufacture of dyes, organic synthesis and intermediates of many pesticides. Enterprises engaged in the production or use of 3,4-dichloroaniline will produce wastewater containing 3,4-dichloroaniline in the process of production and use. Improper disposal will endanger the natural environment and damage the ecology balance. At present, the common 3,4-dichloroaniline wastewater treatment system has the following problems in actual use: 1. The common 3,4-dichloroaniline wastewater treatment system is unstable in operation, high in use cost, and increases the production cost of the enterprise; 2. ,...
