Abstract

A novel advanced oxidation coupling deep biochemical treatment wastewater system comprises an ultraviolet (UV) device, a biochemical reaction pool and a membrane filter device. The UV device comprises a box body. A water inlet pipeline is arranged on one side of the box body. A water drainage pipeline is arranged at the bottom end of the box body. A water outlet pipeline is arranged on the other side of the box body and connected with the water inlet of the biochemical reaction pool. A catalyst reaction tank is arranged on one side of the water inlet of the biochemical reaction pool. A catalyst is arranged in the catalyst reaction tank. A liquid outlet is formed in the portion, close to the top end, of the other side of the biochemical reaction pool and is connected with the membrane filter device through a liquid outlet pipeline. A discharge pipeline is arranged on the membrane filter device. The membrane filter device is additionally provided with a backflow virus killing pipeline connected with the UV device. The system is simple, the occupied area is small, wastewater can be deeply treated, and the treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of sewage treatment. Background technique [0002] The photo-advanced oxidation reaction is an extension of the use of UV technology alone to split water molecules into hydroxyl radicals to remove and reduce total organic carbon (TOC). The generation of hydroxyl radicals (·OH) requires one or more primary oxidizing agents (usually ozone or hydrogen peroxide) and reacts with ultraviolet light. This active substance is the strongest oxidizing agent that can react in water and oxidize almost any kind of compound in the water. Hydroxyl radicals are non-selective reactions, and once formed, pollutants are rapidly split into small inorganic molecules. Generally speaking, the reaction conditions should be strictly controlled during the application process, and photo-advanced oxidation technology can reduce the concentration of pollutants from hundreds of PPM to 5 ppb. The whole process often results in the mineralization ...
