Electro-catalytic membrane wastewater treatment system and electro-catalytic membrane tube thereof

Abstract

The invention discloses an electro-catalytic membrane wastewater treatment system. The system comprises an organic wastewater pool, a mixed valve, a direct current regulated power supply, an electro-catalytic membrane tube, an auxiliary electrode and a penetrating fluid tank, wherein the electro-catalytic membrane tube comprises a ceramic membrane tube substrate which is capable of achieving carbonization conduction by thermal decomposition and chemical vapor deposition of propylene carbon source gas; a catalyst for realizing electro-catalytic oxidation of wastewater is supported on the ceramic membrane tube substrate; the electro-catalytic membrane tube is installed in the penetrating fluid tank; the auxiliary electrode surrounds outside the electro-catalytic membrane tube and an interval is maintained between the auxiliary electrode and the electro-catalytic membrane tube; the water outlet end of the organic wastewater pool is connected with the water inlet end of the mixed valve through a metering pump; the mixed valve is connected with the electro-catalytic membrane tube through a water inlet pipe; the positive electrode and negative electrode of the direct current regulated power supply are respectively connected to the electro-catalytic membrane tube and the auxiliary electrode through wires; and the water outlet end of the electro-catalytic membrane tube is connected with the mixed valve, and a control valve is arranged between the electro-catalytic membrane tube and the mixed valve. The treatment of difficultly-degradable organic wastewater can be realized through the system.

Description

technical field [0001] The invention relates to the technology in the field of wastewater treatment, in particular to an electrocatalytic membrane wastewater treatment system and an electrocatalytic membrane tube. Background technique [0002] Refractory organic pollutants are one of the three major environmental problems affecting human health in the 21st century (refractory organic pollutants, greenhouse effect, and ozone layer destruction), and refractory organic pollutants (or persistent organic pollutants) in the environment It is difficult to degrade, has strong lipophilicity, is easy to enrich in the food chain, can be transported over long distances, is extremely toxic, and brings great harm to the living environment and health of various organisms. With the rapid growth of my country's economy, the pollution of refractory organic wastewater is becoming more and more serious. Especially in the rapid development of pharmaceutical industry, textile printing industry, ...
