Abstract

The invention discloses a dual-reflux efficient anaerobic reaction device and a wastewater treatment method. The dual-reflux efficient anaerobic reaction device comprises a wastewater allocation tank, an anaerobic reactor, a gas-liquid separator and a selective precipitator, wherein facilities for adjusting the temperature, the pH value and the like are arranged in the wastewater allocation tank, and an anaerobic water inlet pipe is connected with the anaerobic reactor; a water distributor, a first-stage three-phase separator and a second-state three-phase separator are arranged at the bottom in the anaerobic reactor; the upper part of the gas-liquid separator is connected with the first-stage three-phase separator and the second-state three-phase separator by virtue of a marsh gas riser pipe respectively, and the bottom of the gas-liquid separator is connected with the water distributor by virtue of an internal reflux pipe; and the upper part of the selective precipitator is connected with an anaerobic water outlet pipe of the anaerobic reactor, the bottom of the selective precipitator is connected with the wastewater allocation tank by virtue of an external reflux pipe, and the external reflux pipe is provided with an adaptive flow control device. The dual-reflux efficient anaerobic reaction device disclosed by the invention is strong in impact resistance, high in anaerobic biochemical removal rate, and beneficial for maintenance of efficient and stable running of the system.

Description

technical field [0001] The invention relates to the technical field of sewage anaerobic biochemical treatment, in particular to a double-backflow high-efficiency anaerobic reaction device and a method for treating wastewater by using the double-backflow high-efficiency anaerobic reaction device. Background technique [0002] With the continuous development of society and economy, production and living consume a larger amount of clean water resources and produce a large amount of highly polluted wastewater. If the waste water is discharged directly without treatment, it will cause serious pollution to the natural environment and make social and economic development unsustainable. Therefore, it is of great significance to treat wastewater to reduce or avoid environmental pollution. [0003] Anaerobic wastewater treatment is a kind of wastewater biological treatment method, which has a history of hundreds of years of application. Anaerobic wastewater treatment is a biological...
