Integrated fumaric acid wastewater treatment device

Abstract

An integrated fumaric acid wastewater treatment device comprises a tank body, a water inlet pipe, a water outlet pipe and six partitions, wherein the water inlet pipe and the water outlet pipe are communicated with two ends of the tank body respectively; the partitions are vertically arranged in the tank body and divide the tank body into a pH adjusting tank, a three-dimensional electrochemical tank, a flocculation sedimentation tank, an anaerobic reaction tank, an aerobic reaction tank and an aeration biofilter which are communicated from left to right; the water inlet pipe is communicated with the upper part of the pH adjusting tank, and the water outlet pipe is communicated with the lower part of the aeration biofilter. The device has the advantages that 1, due to the design of the three-dimensional electrochemical tank and the internal three-dimensional electrochemical reaction structure of the three-dimensional electrochemical tank, different electrode materials can be selected according to different sewage, the electrode material is convenient to replace, the difficulty in packing flushing and packing replacement is reduced, and maintenance and installation are convenient; 2,by the design of the three-dimensional electrochemical reaction structure, organic matter in fumaric acid pharmaceutical wastewater can be carbonized, so that the content of organic matter in the wastewater is reduced, and biodegradable short-chain organic matter is generated by chain breaking.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated fumaric acid wastewater treatment device. Background technique [0002] Fumaric acid, also known as maric acid or lichenic acid, is fumaric acid, a colorless, flammable crystal, a carboxylic acid derived from butene. chemical formula is C 4 h 4 o 4 . Its main source is to oxidize benzene (or butene) to maleic acid (or maleic anhydride) in the presence of a catalyst, and then obtain it through isomerization. [0003] With the development of the pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution. The wastewater produced by chemical and pharmaceutical companies in industrial production is one of the most polluted and difficult to treat industrial wastewater in my country. The complexity of pharmaceutical wastewater and conventional The high consumption and inefficiency of the biochemical treatm...

AI Technical Summary

Problems solved by technology

[0006] 1. The use of the device is relatively energy-consuming, and the use conditions are harsh. Condensation, evaporation, etc. and treatment methods have high requirements for temperature, pressure, and device strength;

[0007] 2. The treatment effect for high-concentration fumaric acid wastewater is poor;

[0008] 3. The biochemical property of fumaric acid wastewater is weak, and there is no better improvement method
