Abstract

The invention discloses an online chemical oxidation dynamic membrane system available for processing the hardly-biodegradable wastewater. The online chemical oxidation dynamic membrane system is characterized by comprising a hydrogen peroxide header tank (1), a ferrous ore powder mixing tank (2), a pH adjusting header tank (3), a circulating tank (4), a circulating pump (5), a membrane and membrane module (6), a recycling tank (7), and a detection control device (8) of flow (L) / temperature (T) / pressure (P) / pH parameter. The outlets of the hydrogen peroxide header tank, the ferrous ore powder mixing tank and the pH adjusting header tank are connected with the circulating tank; the outlet of the circulating tank is connected with the circulating pump; the outlet of the circulating pump is connected with the circulating side of the membrane and membrane module; the detection control device (8) of the flow (L) / temperature (T) / pressure (P) / pH parameter is installed on the outlet pipe of the circulating pump, the outlet of the circulating side of the membrane and membrane module is connected with the circulating tank; a drain outlet is arranged at bottom part of the circulating side of the membrane and membrane module, the drain outlet is connected with the recycling tank; and the production water on the production water side of the membrane and membrane module is sent out of the system. By adopting the system, the product water quality of the base membrane can be greatly increased, the treatment process can be simplified, the removal rate of the chroma, TSS, CODCr, BOD5 and the benzene series can be increased, the contaminant residual amount on the circulating side can be obviously reduced and the wastewater treatment cost can be reduced.

Description

technical field

[0001] The invention belongs to the technical field of refractory biodegradable wastewater treatment, and relates to the dynamic membrane technology in the membrane water treatment technology, in particular to a dynamic membrane filtration system with online formation, continuous transformation, catalytic reaction and adsorption, which is a dynamic membrane and A deeply coupled system of two technologies for Fenton oxidation. Background technique

[0002] my country's per capita fresh water possession is low and the pollution of fresh water resources is becoming more and more prominent. Some of them are polluted by N and P and become eutrophic, or heavy metals are severely exceeded by industrial pollution, and even the pollutants are carcinogenic, teratogenic, and mutagenic substances. Dozens of pollutants are involved, posing a serious threat to water safety. The conventional water treatment process involves multiple units such as coagulation, sedimentation,...
