Device and method for strengthening impact resisting load of anaerobic treatment wastewater

Abstract

The invention discloses a device and a method for strengthening an impact resisting load of anaerobic treatment wastewater. The device comprises a first cylinder and a second cylinder which are connected through a water distribution device. A water inlet hole and a second exhaust hole are arranged at the top end of the first cylinder. The water inlet hole is connected with a sulfate liquor tank through a dosing metering pump. Two first exhaust holes are arranged at the top end of the second cylinder, and active carbon casting holes are respectively arranged on both sides of the body of the second cylinder. According to the invention, acid production stage and methane production stage by anaerobic degradation are effectively separated by controlling the water inlet flow; the biological effect of dominant bacterial community is strengthened by adding particle active carbon to the first cylinder; powder active carbon is cast to the second cylinder as a redox mediator to improve the reaction speed, and the sulfate medicament is selectively cast, so that a good biological environment is easier to form, the dominant bacterial community in each stage comes into play, muddy water is adequately contacted, and the impact resisting load of anaerobic treatment wastewater is enhanced.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and specifically relates to a device and a method for strengthening the shock load resistance of anaerobic treatment wastewater. Background technique [0002] Anaerobic biological treatment technology has been a hot spot in the research of water treatment technology due to its advantages of low investment, low energy consumption, recyclable biogas energy, less sludge production, and impact load resistance. [0003] At present, the UASB reactor is widely used in the field of high-concentration wastewater treatment due to its high sludge concentration, built-in three-phase separator, no mixing equipment, and no carrier in the sludge bed; however, if the design is not good, the sludge It will be lost in large quantities and is sensitive to sudden changes in water quality and load; EGSB and IC reactors are new high-efficiency anaerobic reactors developed on the basis of UASB reactors....
