Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the middle-size and small-size waste disposal plant of the utility model embodiment comprises grille well, equalizing tank, anaerobism dephosphorization pond, anoxic pond, Aerobic Pond, emergency reaction pond, contacted filter tank, blower fan pond, sludge digestion tank, also comprises the mud air-lift device and the recoiling device that are arranged on anaerobism dephosphorization pond, anoxic pond, Aerobic Pond, emergency reaction pond, each bottom, pond, contacted filter tank; Described mud air-lift device and recoiling device are communicated with blower fan in the blower fan pond by pipeline; The mud mouth of described mud air-lift device is opened in described sludge digestion tank.
As shown in Figure 2, described mud air-lift device comprises and carries mud pipe 1, air intake branch 2 and valve 5 thereof, storage mud pit 3, shore pipe 7, air inlet supervisor 6; The lower end of carrying mud pipe 1 places in the storage mud pit 3, air intake branch 2 the lower end of carrying mud pipe 1 with carry mud pipe 1 and be connected, the upper end of carrying mud pipe 1 arranges piston 4, carries mud pipe 1 close piston 4 one ends and is provided with shore pipe 7, air inlet is responsible for 6 and is connected with air intake branch 2, blower fan respectively.Shore pipe 7 with carry mud pipe 1 and stretch into storage mud pit one end and become≤an angle of 90 degrees.
In the working process, at first, valve 5 is opened, this moment, large quantity of air was carried mud pipe 1 by entering with air inlet supervisor 6 air intake branches that are connected 2, and gas is to storage mud pit 3 and the motion of shore pipe 7 both directions afterwards; The air of air intake branch 2 of flowing through can be discharged to the mud that is trapped in air intake branch 2 carries mud pipe 1, and the air that flows to shore pipe 7 can be trapped in the mud of shore pipe and discharge; After valve 5 is closed, air intake branch 2 continued motion and made air pressure reduction in the pipe with the air of carrying in the mud pipe 1 under inertia effect this moment, at this moment, mud in the storage mud pit is through carrying mud pipe 1 and referred shore pipe 7, further be discharged to outside the pipe, in this process, the piston 4 of carrying mud pipe 1 one ends is used for preventing that mud from overflowing.
Described recoiling device comprises perforation recoil tube, air intake branch and valve thereof; The perforation recoil tube in above-mentioned anaerobism dephosphorization pond, each pond bottom even of anoxic pond, Aerobic Pond, emergency reaction pond, contacted filter tank arranges, evenly bore a hole according to certain spacing on the perforation recoil tube, the perforation recoil tube is connected to the air inlet supervisor, by the unlatching of valve control back-purge system.Back-purge system is regularly opened in each pond, prevents that filler from stopping up.
It is as follows that the utility model embodiment respectively installs major function:
Grille well: remove larger floating matter, particularly thread, banded floating matter in the sewage, with the normal operation of protection subsequent disposal structures.
Equalizing tank: large for the water fluctuations in discharge, and therein water quality is regulated, precipitation is removed the suspended particle in the sewage simultaneously.Sewage evenly is promoted to the subsequent disposal structures through lift pump and processes.
Anaerobism dephosphorization pond: the built-in distinctive anaerobism dephosphorization filler in this pond, utilize its acidication ability and the Decomposition of anaerobion to strengthen the decomposing macromolecular organism, make effectively that a large amount of difficult decomposing organic matters are degraded to lower-molecular substance in the sewage, reduce COD, BOD
5, and can effectively remove part phosphorus.Wherein unique deflector type structure has guaranteed fully contacting between sewage and filler in the anaerobism dephosphorization pond, has brought into play to greatest extent the effect of filler, has also improved the adaptability to changes to sudden change of water quality simultaneously, especially to the adaptability to changes of factory effluent.
Anoxic pond: this pond built-in elastic filler, the Aerobic Pond mixed-liquor return so far.Under anoxic condition, utilize in the pond denitrifying bacterium that total nitrogen is carried out denitrification and remove, alleviate the load of rear end nitrogen.
Aerobic Pond: Aerobic Pond has removes ammonia nitrogen and organic effect preferably, and anti impulsion load, and the sludge creation rate is low, flexible operation.Under aerobic condition, the increase of the aerobic microbiological film thickness that adheres on the filler, the difference of oxygen concn in the environment, microbial film changes the double oxygen in outer field aerobic film, middle level and the anaerobism film of internal layer gradually into.At this moment, the gaseous state meta-bolites can constantly be overflowed, and has weakened the sticking power of microbial film on filler, and the biofilm detachment of weather aging is substituted by newborn microbial film.
Emergency reaction pond: when the influent quality fluctuation ratio is larger, in order to guarantee water outlet, in the emergency reaction pond, add medicine, carry out chemical reaction, can more effectively remove TP and BOD
5Also can add PAC; When normal operation, the reflux pump in this pond is extracted into mixed solution in the anoxic pond.
Contacted filter tank: in contacted filter tank, be filled with filtering material and calcium system material.Suspended substance in the SS(water quality that in the aeration tank, flows out) in last pond, is removed, after the decoloration and deodorization of material is processed after filtration simultaneously, obtains highly limpid clean water matter.
The removal of pollutants such as organism, suspended substance and nitrogen phosphorus are finished in above-mentioned anaerobism dephosphorization pond, anoxic pond, Aerobic Pond, emergency reaction pond, the 5 sections combinations in contacted filter tank.
Sludge digestion tank: collect the mud that comprises anaerobism dephosphorization pond, anoxic pond, Aerobic Pond, emergency reaction pond, each pond, contacted filter tank, mud is carried out gravity concentration, supernatant liquor drains into urban sewage pipe, and thickened sludge extraction every half a year in bottom once is transported to the park irrigation band as the fertilizers for potted flowers utilization; The river organic loading of processing low, the sludge quantity that produces every day is few.
The utility model embodiment water outlet reaches " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level B standard.
Leading indicator and the degree for the treatment of of the utility model embodiment Inlet and outlet water water quality see the following form:
Table 1 Inlet and outlet water design objective
(the outer numerical value of bracket is water temperature〉control index 12 ℃ times, the control index when numerical value is water temperature≤12 ℃ in the bracket.）。
