Efficient hydrolysis bioreactor

Abstract

The invention relates to the technical field of sewage treatment equipment, in particular to an efficient hydrolysis bioreactor which comprises a cylindrical reaction cylinder, an adjusting layer forfiltering sewage, a spacing layer and a biological filtering layer for purifying the sewage are sequentially arranged in the reaction cylinder from bottom to top, and an aeration device is arranged atthe upper part of the spacing layer; the adjusting layer is composed of anaerobic granular sludge, the biological filter layer comprises a plurality of carrier devices used for mounting aerobic microorganisms, each carrier device comprises an upper bearing plate and a lower bearing plate which are arranged in parallel, the upper bearing plates and the lower bearing plates are netty, and first suspension balls are filled between the upper bearing plates and the lower bearing plates; one side of the reaction cylinder is communicated with a water inlet pipe, and one end of the water inlet pipe penetrating into the reaction cylinder is connected with a water distribution device located above the adjusting layer; and the reaction cylinder is connected with a water outlet pipe. According to theinvention, the sewage can be rapidly purified by virtue of aerobic microorganisms, and meanwhile, the whole reactor is small in occupied area and easy to maintain and use in the later period.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a high-efficiency hydrolysis bioreactor. Background technique [0002] Domestic sewage is the wastewater discharged by residents in their daily life. Compared with industrial wastewater, the composition of domestic sewage is relatively stable, and the main pollutants are various organic substances and pathogenic microorganisms. In order to prevent domestic sewage from polluting groundwater, it is generally necessary to purify the sewage water body before discharging domestic sewage. There are two commonly used purification methods at this stage, one is the biological aerated filter method, and the other is the activated sludge method. [0003] As far as the biological aerated filter method is concerned, it generally sets fillers in the water body and uses artificial oxygen supply to quickly cultivate aerobic microorganisms that can purify the water body; its ad...

Problems solved by technology

[0003] As far as the biological aerated filter method is concerned, it generally sets fillers in the water body and uses artificial oxygen supply to quickly cultivate aerobic microorganisms that can purify the water body; its advantages are low energy consumption and large buffer capacity, which can It can withstand a wide range of water flow rate fluctuations, and at the same time, the amount of sludge produced in the whole process is small; however, the biological aerated filter method occupies a large area, so its construction cost is relatively high, and at the same time, it has a high impact on the solid suspension concentration of sewage The requirements are also relatively strict, so a certain pre-settlement treatment is required for the sewage, and because the surface layer of the biofilter is enriched in nutrients, it is easy to breed flies; another point is that when the microorganisms in the water body age and die , the aging biofilm left behind will gradually accumulate in the water body, which will reduce the flow rate of the sewage water body

[0004] For the activated sludge method, it uses artificial oxygen supply to continuously mix and cultivate sewage and various microbial groups to form activated sludge, and utilizes the biological coagulation, adsorption and oxidation of activated sludge to treat sewage. Decompose the organic pollutants in the water; its advantage is that its floor area is slightly lower than that of the biofilter method, and its treatment efficiency for water is slightly higher than that of the biofilter method; however, the overall maintenance cost of the activated sludge method is higher, And prone to sludge bulking
