The utility model content
The technical problem that the utility model will solve is: in order to solve the deficiency of above-mentioned technology, a kind of sewage integrated treatment unit is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of sewage integrated treatment unit; Comprise anoxic pond, anaerobic pond, Aerobic Pond, settling tank, airing system and mud return-flow system; Said anoxic pond is located at the anaerobic pond inner chamber, and the anoxic pond bottom is communicated with the anaerobic pond inner chamber, and the anoxic pond top has the water inlet pipe that is used to feed sewage; Said anaerobic pond top has the methane recovery device that is used to collect biogas; The top of anaerobic pond inner chamber is communicated with through overflow weir with Aerobic Pond inner chamber top, and Aerobic Pond inner chamber middle part is communicated with through overflow weir with settling tank inner chamber middle part, and settling tank top has and is used to discharge the water outlet of handling sewage later; Be provided for the airing system of oxygen supply in the Aerobic Pond; Said mud return-flow system has entrance end and exit end, and entrance end is positioned at the position near the settling tank bottom, and exit end is communicated with anoxic pond.Anoxic pond is located at the anaerobic pond inner chamber, compares traditional series connection setting, effectively reduces the floor space of waste disposal plant, reaches utilization of resources maximization; Also have biogas simultaneously in anoxic pond and the anaerobic pond and occur, this part biogas collects through special methane recovery device, is used for elswhere, plays the effect of energy-conserving and environment-protective again.
In order to make anoxic pond effectively be fixed on the anaerobic pond inner chamber, said anoxic pond bottom has leg, and the leg of anoxic pond is fixedly connected with anaerobic pond inner chamber bottom surface.
Collecting methane for ease, the top of anaerobic pond is to the arch of outer lug or ridge shape.The design of arch or ridge shape is convenient to make biogas to come together in the pond inner top.
Effect of settling is strengthened in cleaning for ease, and said settling tank bottom is progressively convergent structure wide at the top and narrow at the bottom.Traditional smooth bottom be unfavorable for mud from main flow, adopt after the progressively convergent structure wide at the top and narrow at the bottom, can effectively reduce edge corner deposition dirt, simultaneously also easy cleaning.
For the ease of the operation and maintenance of airing system and mud return-flow system, airing system has gas blower, and the mud return-flow system has sludge reflux pump, and said gas blower and sludge reflux pump all are located at the outside of Aerobic Pond and settling tank.
In order to prevent that biogas is leaked in the extraneous air, the exit end of said water inlet pipe and mud return-flow system all is located at below the sewage level.Even biogas flows out and also can not pass in the extraneous air like this, security is guaranteed.
The beneficial effect of the utility model is that the sewage integrated treatment unit of the utility model has reduced floor space; Can realize qualified discharge after the WWT; Apparatus structure own is simple, cheap, convenient installation and operation, has increased methane recovery simultaneously, save energy.
