Abstract
The utility model discloses a sludge discharge and sludge return system of an efficient precipitation tank. The efficient precipitation tank comprises a concentration sludge discharge area arranged at the bottom of a main tank body, and is characterized in that the system comprises a sludge discharge hopper arranged at the tail end of the concentration sludge discharge area at the bottom of the main tank body and a sludge discharge groove positioned at the upper part of the sludge discharge hopper, wherein a sludge air lifting device is arranged between the sludge discharge groove and the sludge discharge hopper, the sludge discharge groove is connected with an intermediate sludge storage tank, and the intermediate sludge storage tank is respectively provided with a sludge return pump group and a sludge discharge pump group. The technology disclosed by the utility model can better monitor the solid content in sludge, flexibly regulate the return and the discharge of the sludge, be easier to control the concentration and the return ratio of the returned sludge, further ensure the water quality of the outlet water of the efficient precipitation tank and simultaneously further improve the sludge concentration discharged to a sludge treatment system.
Description
Technical field
The utility model relates to a kind of spoil disposal and sludge reflux of efficient sedimentation tank, specifically the spoil disposal of efficient sedimentation tank and sludge reflux system in a kind of water supply factory's conventional treatment and Sewage Plant coagulation.
Background technology
At present, the traditional tank types such as the conventional treatment of waterworks, Sewage Plant processing and the more employing horizontal sedimentation tank of extraordinary water treatment, accelerator, tube settler, but because these three kinds of pond types exist respectively floor space larger, the spoil disposal water yield is more, and is relatively poor to the low temperature and low turbidity water treatment effect; The more difficult control of mixed flocculation part body refuse concentration, the effluent quality susceptible to; Inhomogeneous so that the effluent quality of water distribution improves the shortcomings such as difficulty.The applicant has researched and developed middle efficient sedimentation tank and full Chinese style efficient sedimentation tank for above-mentioned shortcoming.These two kinds of pond types are guaranteed the Inlet and outlet water even water distribution efficiently utilizing pond body plane area, improve the capacity of resisting impact load aspect and obtain than much progress, but aspect more accurately controlling the spoil disposal time, controlling reflux ratio, also need further to be improved.
The utility model content
The purpose of the utility model technology is to provide a kind of efficient sedimentation tank spoil disposal and sludge reflux system, it can be so that thickened sludge enters a sludge circulation system that is easier to control, by monitoring its solid content, solve these two kinds of pond type spoil disposal times, reflux ratios and control the problem that many dependence experience is determined, whole technique unit adaptation time when effectively shortening the operating mode change, better guarantee effluent quality, can further improve the sludge concentration that drains into sludge treating system simultaneously.
To achieve these goals, the technical solution of the utility model is: a kind of efficient sedimentation tank spoil disposal and sludge reflux system, described efficient sedimentation tank comprises the concentrated soil discharging area that is arranged on the main tank body bottom, it is characterized in that this system mainly comprises the mud-removing bucket of being located at main tank body bottom concentrated soil discharging area end, be positioned at the mud drainage slot on mud-removing bucket top, be provided with sludge lifting device between mud drainage slot and mud-removing bucket, this mud drainage slot is connected with middle storage basin, and middle storage basin is respectively equipped with sludge reflux pump group and mud discharging pump group.In the middle of described, storage basin is arranged at outside main tank body.Described sludge lifting device is the mud air-lift device.In the middle of described, storage basin is connected with the water inlet pipe of main tank body by the sludge reflux pump group, and described middle storage basin is connected to sludge treating system by mud discharging pump group.Described efficient sedimentation tank is inter-phase sedimentation basin or full Chinese style sedimentation basin.
The utility model has the advantage of and better to monitor the mud solid content, the backflow of flexible modulation mud and discharging, make concentration and the reflux ratio of returned sludge more easy to control, the effluent quality of efficient sedimentation tank can be further guaranteed, the sludge concentration that drains into sludge treating system can be further improved simultaneously.

The specific embodiment
Be further described below in conjunction with accompanying drawing.
As shown in Figure 1, this efficient sedimentation tank mainly comprises the mud-removing bucket 1 of being located at main tank body bottom concentrated soil discharging area end, be positioned at the mud drainage slot 2 on mud-removing bucket top, mud air-lift device 3 with mud drainage slot 2 combination settings, be independent of the middle storage basin 4 outside main tank body, the sludge reflux pump group 5 and the mud discharging pump group 6 that arrange respectively.It is different from the prior art part and is: (1) concentrated soil discharging area end bottom main tank body is not established the spoil disposal canal of the single gradient, changes some mud-removing buckets 1 into and collects mud; (2) being different from prior art directly refluxes thickened sludge in the spoil disposal canal or discharging by the pump group, but being promoted by air-lift device 3, the interior mud of mud-removing bucket 1 is expelled to the mud drainage slot 2 of being located at mud-removing bucket 1 top, mud drainage slot 2 confluxes mud to the middle storage basin 4 that is independent of outside main tank body, sludge reflux pump group 5 and mud discharging pump group 6 be VFC respectively, mud after further concentrating from middle storage basin 4 absorptions, the former mud extraction is to the water inlet pipe of main tank body, and latter's mud extraction is to sludge treating system.the corresponding cover air-lift device 3 of every grillages bucket 1 and every cover air-lift device 3 can be controlled separately, make concentrated soil discharging area end spoil disposal more all even effective, in addition, the design of the design of mud drainage slot 2 and middle storage basin 4, make the mud solid content more easily monitor, also more directly perceived, coordinate the sludge reflux pump group 5 and the mud discharging pump group 6 that arrange respectively, make the 1 spoil disposal time of mud-removing bucket, middle storage basin 4 backflows and drain time are also corresponding more flexible, more can guarantee effluent quality, moreover, further concentrate by 4 of middle storage basin, can improve preferably the sludge concentration that drains into sludge treating system.Air-lift device 3 belongs to prior art, is not described in detail at this.
