Gas guide type anaerobic reactor

Abstract

The invention relates to a gas guide type anaerobic reactor. The gas guide type anaerobic reactor comprises one or a plurality of anaerobic reaction tanks connected in series; a water inlet, a water outlet, an exhaust port and a slag outlet are formed in the outer part of each of the anaerobic reaction tanks; a feed plate, a guide plate and a sludge plate are arranged at the inner part of each of the anaerobic reaction tanks, wherein the feed plate is arranged at one side close to the water inlet; the sludge plate is arranged at one side close to the water outlet; the guide plate is arranged between the feed plate and the sludge plate; the guide plate and the sludge plate are movably connected to the inner part of each of the anaerobic reaction tanks; the feed plate and the guide plate define a sludge suspension area; the guide plate and the sludge plate define a precipitating area; a reaction area is formed in the bottom part of each of the reaction tanks. Compared with the prior art, the gas guide type anaerobic reactor has the advantages that the muddy water reaction time and the sludge precipitation time can be adjusted by controlling the volumes of the sludge suspension area and the sludge precipitating area; in addition, the gas guide type anaerobic reactor has good load to impact, and is high in fermenting efficiency, wide in applicable range, high in sludge utilization rate, low in energy consumption, simple in design, and convenient in equalization.

Description

Technical field [0001] The invention relates to the field of wastewater treatment, in particular to an anaerobic reactor with gas diversion. Background technique [0002] The anaerobic reactor is mainly used to treat livestock and poultry breeding wastewater, agricultural straw waste, and kitchen waste. The anaerobic reactor has gone through about three generations of reactors since its origin. The first generation of reactors has no separation of hydraulic retention time and sludge retention time, and the second generation of reactors achieves hydraulic retention time and sludge retention. In addition, anaerobic microorganisms can attach to the surface of the carrier to form granular sludge. The third-generation reactor further improves the good contact between the influent and the sludge. In short, each generation of the reactor is designed to form a large amount of sludge. Activated sludge and improve the direction of reactor mud-water contact are developed. Conventional ana...

Problems solved by technology

However, the disadvantages of this patent are: forced internal circulation requires large energy consumption, the system design requirements are relatively high, and the multi-stage anaerobic reactor is designed in the longitudinal direction, the reaction level should not be too many, the construction is complicated, and it is not convenient for engineering change

However, the disadvantages of this patent are: the circulation of sludge depends on the forced circulation of external power, which requires a lot of energy consumption, the reactor needs more baffles, more construction consumables, and the operating costs and investment costs are correspondingly high.

However, the disadvantage of this patent is that the sludge is deposited in the last stage of the reaction tank, the sludge retention of each stage is relatively low, and the amount of sludge produced is relatively large. If the sludge circulation is required, it needs to be forced by external power. cycle
