Problems solved by technology

Because there are many water outlet points, the outlet flow rate is slow, easy to block, or form channel flow, which affects the effect
And the pipeline is complicated and the reliability is poor
[0004] On the other hand, the quality of wastewater entering the reactor often has large fluctuations, such as pH, concentration, content of toxic substances, etc. These factors are likely to cause adverse reactions of microorganisms in the reactor, resulting in unstable operation

Abstract

The invention discloses a reflux liquid inlet device for a high-load anaerobic reactor, which comprises an anaerobic reactor, wherein the upper end of the anaerobic reactor is connected with a water outlet pipeline which is connected with a pipe circulating pump, the circulating pump is connected to a mixing device through a pipeline, the mixing device enters the bottom of the anaerobic reactor through a liquid inlet pipe, and an anaerobic liquid inlet pump is connected to the mixing device through a pipeline. The mixing device comprises a mixing cavity, the center of the top of the mixing cavity is provided with an inlet for wastewater to be treated, the middle at the right side of the mixing cavity is provided with a circulating water inlet which is connected with a nozzle positioned in the mixing cavity, and an external nozzle is arranged outside the mixing cavity. The invention changes the traditional multi-point water inlet mode of the anaerobic bioreactor.

Description

technical field [0001] The invention relates to the fields of environmental protection engineering and chemical engineering, in particular to a backflow liquid inlet device for a high-load anaerobic reactor. Background technique [0002] The huge advantages of anaerobic technology in terms of energy saving, material and energy recovery, and ecological benefits make environmentalists see its key role in sustainable development and circular economic models, and believe that anaerobic biological treatment technology for wastewater has become a sustainable The core technology of development. [0003] Anaerobic bioreactor is a type of reactor for wastewater treatment, among which the upflow anaerobic sludge bed reactor (UASB) and pumped granular sludge bed (EGSB) are the representatives. The wastewater passes through the anaerobic sludge bed from bottom to top. There are dense microorganisms (sludge bed) in the lower part of the reactor, the suspended layer in the middle, and th...
