Description
Technical field
The utility model relates to the equipment for separating liquid from solid of suspension in sewage disposal system, refers in particular to the device of a kind of scavenger precipitation pond mud scum.
Background technology
Sedimentation basin is to utilize precipitation to remove a kind of structures of suspension in waste water, is used for separation from Aerobic Pond mud mixture out, and sedimentation basin water outlet enters anoxic pond and processes after flowing into recirculation water absorbing well, absorption well.Activated sludge is sent Aerobic Pond back to and is recycled, and part excess sludge is sent into sludge concentration tank.
The effect of anoxic pond is that organic matter in intaking is as denitrifying carbon source and the energy, the nitrate nitrogen of usining in recirculation water is as denitrifying oxygen source, under biomembrane in pond on combined stuffing (facultative cenobium) effect, carry out anti-nitration reaction, make the polluters such as COD in waste water, nitrate nitrogen, nitrous acid nitrogen be removed and degrade.Therefore, if to contain mud more for recirculation water in reflux sedimentation tank, mud can gather or be attached on biologic packing material in biologic packing material intermembrane space, and then stop up filler passage or cause the damage of biologic packing material, affect the carrying out of anti-nitration reaction on biomembrane, reduce removal and the degradation of Pollutants in Wastewater matter.Meanwhile, also can increase the obstruction of anoxic pond water-locator pipeline and the risk that water-locator is revealed.
Scum silica frost in sedimentation basin wastewater treatment is mainly to contain organic mud, cause the main cause of mud floating to comprise that surface loading is too high, activated sludge is aging, mud is poisoning and denitrification occurs mud in infall process, especially at biochemical system, occur that when abnormal, sedimentation basin mud scum phenomenon is particularly frequent.At present in water treatment field, for the processing of scum silica frost, never have very effective method.Conventionally adopt to add defoamer or flocculant, bio anaerobic digestion method or add skim, filter plant precipitation mud scum or suppress mud scum and flow out with supernatant.But this several method has drawback.
At present the domestic sedimentation basin for wastewater treatment adopts swinging mud scraper to collect mud mostly, and mud scraper scraper plate will be sink to the sludge bucket at the sludge scraping Zhi Chi center at the bottom of pond, relends gravity or sludge pump is drained.Supernatant is entered in water outlet and is imported in outlet pipe by V-type or U-shaped downflow weir simultaneously, but generally do not establish fender configuration or its mud guard, it is the circular steel plate of a monoblock, be fixed in sedimentation basin main body, once and there is the loosening or distortion of mud guard, easily cause water outlet skewness, top mud scum is easily by entering in recirculation water, and installation and maintenance inconvenience.
Utility model content
The purpose of this utility model is in order to solve the problem of the mud scum poor removal effect of sedimentation basin overflow device in existing wastewater treatment, the device of a kind of scavenger precipitation pond mud scum is provided, and it is a kind of simple installation and the equipment that can efficiently realize the liquid-solid separation of sedimentation basin waste water surface mud scum.
The purpose of this utility model is achieved through the following technical solutions:
A device for scavenger precipitation pond mud scum, it comprises:
Sedimentation basin, it is the pond of cylindrical shape, its center is provided with stabilizing feed well, the pool wall middle part of sedimentation basin is provided with the water intake that enters waste water, on the sedimentation basin pool wall top on water intake opposite, be provided with the recirculation water delivery port of discharging recirculation water, the pool wall bottom of sedimentation basin is provided with the mud discharge pipe of discharging mud;
Sedimentation basin body, be located at sedimentation basin internal upper part, it is the cylindrical shape concrete component that an external diameter is less than sedimentation basin pool wall internal diameter, its top is also opened wide in sedimentation basin, its bottom stretches out and is fixedly connected with sedimentation basin pool wall, make to form between sedimentation basin body and sedimentation basin the water outlet of an annular, described recirculation water delivery port is located on the sedimentation basin pool wall in water outlet outside;
Downflow weir, it is circular plate, bottom is fixed on the sedimentation basin body of water outlet inner side, top indentation;
Mud scum baffle plate, it is circular plate, is fixed on the inner side of downflow weir by several fixed supports; Described fixed support is a Z-shaped supporting frame, its one end is provided with rectangle screw, in rectangle screw, by screw, this end is fixed on mud scum baffle plate, its upper shelf is at the top of downflow weir, and its other end is screwed in the concrete of sedimentation basin bodies top.
The width of described water outlet is 30cm.
The height of described downflow weir is 15cm.
Described mud scum baffle plate is arranged on 15cm place inside described downflow weir.
Described mud scum baffle plate height is 40cm, and thick is 3mm, adopts stainless-steel sheet to make, and its top is higher than downflow weir top 5cm, and bottom is lower than the bottom 20cm of downflow weir.
The beneficial effects of the utility model:
The design that the utility model has the advantage of mud scum baffle plate has improved the separating effect of sedimentation basin surface mud scum with recirculation water greatly, avoids in anoxic pond to the obstruction of biologic packing material clearance channel and the obstruction to water-locator the Biochemical Treatment of raising waste water.Meanwhile, because floating sludge activity and sedimentation function in reflux sedimentation tank are better, can reduce the consumption of activated sludge, improve the mud utilization rate of biochemical system.In addition,, because mud scum baffle plate described in the utility model is fixed by screw but not Type of Welding in the past, therefore can come secondary to regulate the levelness of mud scum baffle plate by changing the fixed position of screw.
