Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 As shown, the anaerobic membrane bioreactor consists of a tank body 7, a swirl water distributor, a sampling device 8, an anaerobic membrane module 2, an anaerobic membrane module 3, a biogas booster pump 1, a circulation pump 5, an outlet pump 6 and Composition of 4 water packs. The upper opening of the tank body 7 communicates with the anaerobic membrane module 2, and the tank body 7 is connected to the sampling device 8 through several sampling pipes, and the sampling pipes are set at different heights of the tank body 7 to regularly monitor the amount of sludge in the tank body and the amount of sludge Traits provide guidance for the operation of the tank.

[0033] The anaerobic membrane module is composed of high-strength anti-pollution anaerobic hollow fiber membranes. The anaerobic hollow fiber membranes do not need to b...

Abstract

The invention discloses an anaerobic membrane bioreactor. The anaerobic membrane bioreactor comprises a tank, the bottom in the tank is provided with a cyclone water distributor, the cyclone water distributor is connected with a water diversion bag arranged outside the tank, the upper portion of the outside of the tank is provided with an anaerobic membrane module connected with the inside of the tank, one end of the anaerobic membrane module is connected with an outlet water pump, and the other end is connected to the water diversion bag through a circulating pump; and the upper portion of the tank is connected with a biogas pressurizing pump, the biogas pressurizing pump is connected to a biogas outlet at the top of the tank, and biogas pressurized by the biogas pressurizing pump is conveyed to the anaerobic membrane module as an anaerobic membrane module stirring gas source. The anaerobic membrane reactor has the advantages of high treatment load, small occupied area, stable quality of outlet water, basically no SS, stable running, engineering investment reduction due to no need of particulate sludge, permanent effectiveness of once added sludge bacterium strain, energy consumption and running cost reduction due to no aerobic treatment of wastewater with low requirements, and basically no manual operation due to high automation degree.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to an efficient anaerobic membrane bioreactor. Background technique [0002] The anaerobic reactor has high treatment efficiency and low energy consumption, and plays an irreplaceable role in the field of high-concentration wastewater treatment. For any type of anaerobic treatment system, having high removal efficiency and stable operation is the key to measuring the quality of a reactor , and anaerobic sludge is the main factor to ensure that the anaerobic reactor can run well. Therefore, a large number of different anaerobic process technologies have been developed from different effective gas-liquid-solid three-phase separation technologies, such as UASB (upflow anaerobic sludge bed), EGSB (expanded granular sludge bed), IC (internal circulation anaerobic sludge bed), etc. Oxygen reactor), ABR (upflow packed anaerobic reactor), etc., each anaerobic reactor s...
