preparation example Construction

[0048] The preparation method of the filter packing is as follows: according to the inoculum amount of 10-100 mg / L, inoculate nitrifying bacteria, yeast, lactic acid bacteria, bacillus and pseudomonas on the filter packing matrix, so that the dissolved oxygen concentration is lower than 2.0 mg / L L, the natural or artificial sewage with a pH value of 7-8 is used to cultivate the inoculated filter packing matrix, and gradually increase the dissolved oxygen concentration in the sewage until it reaches 3-5.0 mg / L. When the effluent ammonia nitrogen removal rate reaches 50% and turbidity When the degree is reduced by more than 70%, the filter packing is obtained.

[0049] In the present invention, the preparation method of the biological aerobic filler is: inoculate nitrifying bacteria, yeast, lactic acid bacteria, bacillus and pseudomonas on the biological aerobic filler matrix according to the inoculum amount of 10-20 mg / L, The inoculated biological aerobic filler matrix is ​​cul...

Abstract

The invention provides an aeration sewage treatment device. The aeration sewage treatment device comprises a submerged microporous aeration unit and a microbiological treatment unit. The submerged microporous aeration unit comprises a blower, a base and a plurality of microporous aeration pipes, wherein the blower is connected with the microporous aeration pipes through connecting pipes, and the microporous aeration pipes are fixed to the base in parallel. The microbiological treatment unit is arranged on the downstream of the microporous aeration unit, and comprises a frame and perforated partition plates in the frame, wherein the frame is composed of perforated baffles, the perforated partition plates divide the interior space of the frame into a filter unit and biological aerobic units,the filter unit and the biological aerobic units are filled with filter filler and biological aerobic filler respectively, and the filter unit is located on the upstream of the biological aerobic units. The dissolved oxygen concentration of outlet water after treatment by the device reaches 3 mg / L to 8 mg / L, the ammonia nitrogen removal rate reaches 80% or above, the turbidity is reduced by 70% or above, the outlet water can be directly discharged into a natural or artificial water body, and the sewage treatment efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an aeration sewage treatment device. Background technique [0002] Natural or artificial water body aeration methods generally include surface aeration and deep aeration. Aeration etc. Among them, fountain aeration and solar aeration belong to surface aeration, mainly to aerate and oxygenate the upper water body, and its surface is in contact with the atmosphere, which has a certain reoxygenation effect, while the middle and lower polluted water bodies that are anoxic cannot be reoxygenated. , the surface aeration efficiency is low; push flow, jet flow, submerged flow, nano or microporous aeration can achieve the effect of deep aeration, but it is only suitable for still water polluted water bodies, and the oxygenation efficiency is low in water bodies with a certain flow rate. Contents of the invention [0003] Aiming at the problems in the prior art that the surfac...
