Abstract

The invention provides a micro-series-wound photoelectric catalysis oxidation wastewater treatment device which is characterized by consisting of a plurality of cathode chambers and anode chambers separated by anion selective permeable membranes, wherein the anion selective permeable membranes are located between the cathode plates and the anode plates. The device is internally divided into a plurality of cathode chambers and anode chambers sequentially arranged. A plurality of light sources are arranged inside each anode chamber which is filled with a photoelectric catalyst. The anode chambers are main chambers for wastewater treatment, and adjacent anode chambers are connected through the anode plate, so that all anode chambers in the device are in a micro-series-wound state. Each cathode chamber is filled with a cathode plate anti-scaling liquid, and bottoms of all cathode chambers are intercommunicated. The micro-series-wound photoelectric catalysis oxidation device provided by the invention not only can improve the photoelectric treatment efficiency, but also can effectively solve the problem that the light sources and the plates are hardened when high hardness wastewater is treated, so that frequent cleaning is avoided, and long-term stable operation of the device is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of high-salt wastewater treatment, in particular to a micro-series photoelectric catalytic oxidation wastewater treatment device. Background technique

[0002] In recent years, the country has become more and more demanding on environmental protection, and has clearly stipulated the discharge standards for the external drainage of petrochemical enterprises, requiring the external drainage to be further reduced, or even close to zero discharge, and improving the water reuse rate has become a current research topic. hotspot. More and more refineries use ultrafiltration-reverse osmosis double-membrane method to treat refinery oily wastewater for reuse, so as to reduce the amount of external discharge. However, the ultrafiltration-reverse osmosis double-membrane method can only produce about 75% of reused purified water, and the remaining 25% of double-membrane concentrated water has the characteristics of smal...
