Loading cycle anaerobic organism water treatment device and enhanced anaerobic water treatment method

Abstract

The invention discloses a loading cycle anaerobic organism sewage treatment device and an enhanced anaerobic water treatment method applying the loading cycle anaerobic organism sewage treatment device. The device comprises a treatment container, wherein a loading cycle main reaction area is arranged in the treatment container; liquid flow inner circulation is built in the loading cycle main reaction area, and iron powder and activated carbon are added; the iron powder, the activated carbon and granule sludge in sewage jointly participate in the liquid flow inner circulation. The liquid flow inner circulation realizes interphase high-efficient mass transfer of the suspended-state iron powder, the activated carbon and the granule sludge; the iron powder and the activated carbon build a micro electric field; refractory organic pollutants are acted by an oxidation-reduction effect of the micro electric field, a reduction effect of zero-valent iron, activated carbon adsorption and an anaerobic organism coupling effect, so that the biotoxicity and the biological inhibition of refractory organic waste water in the petrochemical industry field are effectively reduced, and the oxidation efficiency and the biological response rate of anaerobic organisms are improved.

Description

technical field [0001] The invention relates to a sewage treatment device and a treatment method, in particular to the treatment of refractory petrochemical sewage. Background technique [0002] The petrochemical industry involves many industries and plays an important role in the national economy. It is one of the pillar industries of our country. However, a large amount of industrial wastewater is produced in the process of petroleum processing and treatment, and its water quality is complex, mainly containing organic pollutants such as nitriles, esters, alkanes, alkynes, and benzenes, showing high concentrations of organic matter, high biological toxicity, and Characterized by low biochemical properties and high nitrogen content, it is a typical high-concentration refractory organic wastewater. Elimination of refractory persistent organic pollutants has become an important task in the field of environmental protection. [0003] Biological treatment technology has attract...
