Abstract
The embodiment of the invention discloses a biochemical reaction device. The biochemical reaction device comprises an oxygen-deficient reaction zone, an oxygen-eliminating zone and an aerobic reaction zone, wherein the oxygen-deficient reaction zone, the oxygen-eliminating zone and the aerobic reaction zone are respectively spaced by partition plates in sequence, the aerobic reaction zone is filled with cured oxygen-deficient bacterium particles, a waste water inlet is formed in the bottom, a backflow water outlet is formed in the upper portion, the waste water inlet and the backflow water outlet are corresponding connected with a waste water inlet pipe and a backflow pipe, a first water pump is arranged on the waste water inlet pipe, the backflow pipe is connected with the waste water inlet pipe, an MBR membrane module is arranged inside the oxygen-deficient reaction zone and is communicated with the bottom of the aerobic reaction zone through a pipe, and a second water pump is arranged on the pipe. The aerobic reaction zone is filled with a filler and aerobic bacteria, a waste water outlet pipe is arranged at the upper portion, and an aerator is arranged at the bottom and is connected with an air compressor outside the device through a pipe. In the scheme, the MBR membrane module is not easily polluted or blocked, the strain concentration is high, a reaction system is stable, and the treatment costs are low.
Description
technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a biochemical reaction device. Background technique [0002] Ammonia nitrogen wastewater mainly comes from petrochemical, coal gasification, metallurgy, paint, leather tanning, pigment, chemical fertilizer and coking industries. Direct discharge of ammonia nitrogen wastewater into rivers will cause eutrophication of the water body, resulting in the rapid reproduction of algae and other plankton, the decrease of dissolved oxygen in the water body, the deterioration of water quality, and the massive death of fish and other organisms due to lack of oxygen. When the ammonia nitrogen in the water exists in the form of oxide nitrite nitrogen, it can reduce the animal's resistance, destroy red blood cells, and cause the loss of blood oxygen supply capacity, and the nitrite nitrogen can also make the animal's liver, spleen and kidney function weakened. Therefore, ammonia ...
