Rural domestic sewage treatment system

Abstract

The invention relates to the technical field of sewage treatment, and concretely relates to a rural domestic sewage treatment system. The system comprises a tank body, three observation pipes communicating with the interior of the tank body are fixed to the top surface of the tank body at equal intervals, the top surfaces of the three observation pipes are each covered with a top cover, and a water inlet pipe and a water outlet pipe communicating with the interior of the tank body are fixed to the outer walls of the two short side edges of the tank body correspondingly. A transmission gear frame is arranged to drive an upper movable blocking plate and a lower movable blocking plate which move relative to each other to control sediment in a corresponding bin body to be collected to a residue collecting plate, a spiral conveying paddle is driven by a first motor to conduct conveying, and residue discharge pipes which are independent of each other are centralized, so the residue removal efficiency of the treatment tank can be improved; and a movable aeration frame is arranged, a driven gear is meshed with a vertical rack rod to drive an air outlet pipe to rotate. Compared with an existing aeration mechanism, an aeration mechanism in the invention is small in size, wide in aeration action range, good in aeration effect and beneficial to improving the sewage purification efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a rural domestic sewage treatment system. Background technique [0002] Rural domestic sewage treatment is to remove and degrade harmful substances and environmental pollution components in domestic sewage for harmless treatment. Rural domestic sewage treatment should focus on the selection of mature and reliable technologies suitable for rural characteristics and actual sewage treatment. Rural sewage treatment can neutralize the water quality and agricultural products according to the actual situation, so as to achieve reuse and environmental protection degradation discharge. [0003] At present, the common method of rural domestic sewage treatment is to first settle the domestic sewage through the treatment tank, then carry out gas explosion, and then carry out precipitation, so as to treat the harmful substances in the sewage, so as to achieve the water body that mee...

Problems solved by technology

[0003] At present, the common method of rural domestic sewage treatment is to first settle the domestic sewage through the treatment tank, then carry out gas explosion, and then carry out precipitation, so as to treat the harmful substances in the sewage, so as to achieve the water body that meets the requirements of environmental protection. The existing rural In the domestic sewage treatment device, the primary sedimentation chamber, the secondary sedimentation chamber and the gas explosion chamber are isolated from each other, so each time a separate slag removal operation is required, which affects the slag removal efficiency. At the same time, the existing gas explosion structure has a limited range of activities. Poor gas explosion effect, affecting sewage purification efficiency
