Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic reactors, in particular to an anaerobic reactor for treating pesticide intermediate wastewater. Background Art

[0002] The production process of pesticide intermediates produces a lot of wastewater containing organic matter, which needs to be purified by an upflow anaerobic sludge blanket reactor. The existing upflow anaerobic sludge blanket reactor consists of a sludge reaction zone, a gas-liquid-solid three-phase separator and a gas chamber. Sewage enters from the bottom of the reactor, and the organic matter in the sewage is decomposed by microorganisms in the sludge reaction zone to produce biogas, water and inorganic matter. Gas, liquid and solid are separated at the three-phase separator at the top of the reactor to achieve three-phase equilibrium, and the water after the reaction is forced to flow back to the bottom of the reactor.

[0003] According to patent CN 215403347 U, an anaerobic reactor for treating pesticide intermediate wastewater includes an anaerobic tower, an inlet pipe and a return pipe. The inlet pipe is located at the top of the anaerobic tower, and the return pipe is located at the top of the outside of the anaerobic tower: a water distribution trough is arranged at the top of the anaerobic tower, and one end of the inlet pipe is connected to the water distribution trough: a water distribution system is arranged at the bottom of the interior of the anaerobic tower, and a central pipe is connected between the water distribution trough and the water distribution system.

[0004] The patent allows sewage to enter the top of the anaerobic reactor, and the effluent after the reaction overflows from the top of the overflow weir, and then flows back to the water distribution tank at the top of the anaerobic reactor to be mixed with sewage. The distance from the overflow weir to the water distribution tank in the present application is shorter than the distance from the liquid surface of the traditional anaerobic reactor to the forced return pipe. The distance for the submersible sewage pump to overcome the gravity of water is short, which can reduce the power consumption of the submersible sewage pump. However, the patent directly mixes pesticides with water, but the pesticides contain other impurities, which will affect the work of the anaerobic reactor. Utility Model Content
