Abstract
The utility model provides a buried domestic sewage treatment device and relates to an improvement on the structure of the buried domestic sewage treatment device. The buried domestic sewage treatment device is short in decomposition period of organic matters, small in odor and convenient to clean. The buried domestic sewage treatment device comprises a primary settling pond, an anaerobic pond, a contact oxidation pond, a secondary settling pond, a disinfecting pond and a clean water pond, wherein the contact oxidation pond is provided with a gas outlet; and a bamboo charcoal filtering layer is arranged in the gas outlet of the contact oxidation pond. The buried domestic sewage treatment device is buried underground. Two sludge ponds are arranged at the bottoms of the primary settling pond and the secondary settling pond, so that the sludge at the bottom of the device can be cleaned away conveniently; a sludge well is arranged on the side of the device and is connected with the two sludge ponds respectively, so that all the sludge enters the sludge well; and a cleaning worker can remove the sludge from the well by opening a well cover without opening a top cover of the device, so that the labor intensity is greatly reduced.
Description
Technical field
The utility model relates to the improvement to the buried under earth type sewage treatment equipment structure.
Background technology
China is populous, has produced the quite huge sewage of quantity thus.The processing of sewage at present mainly is transported to sewage work by the underground sewage network in cities and towns and adopts conventional activated sludge process to focus on.But in some antiquated cities, be the ancient building on protection ground, still using original water exhaust system all the time.Along with the variation of resident living condition in the antiquated city, these original water exhaust system can not satisfy people's request for utilization.But carry out the big area excavation, build new sewage network, can form serious destruction the ground ancient architecture.Therefore, in the place that is fit to, small-sized buried under earth type sewage treatment equipment is set just seems very for necessary.But there is two large problems in existing buried under earth type sewage treatment equipment: the one, and the peculiar smell of emission gases is big; The 2nd, throw out (mud) cleaning is inconvenient, need open the top cover of whole device, just can draw out the mud of bottom.
Summary of the invention
The utility model provides a kind of organism decomposition cycle short to above defective, and smell is little, clears up buried under earth type sewage treatment equipment easily.
The technical scheme of the utility model is: comprise preliminary sedimentation tank, anoxic pond, contact-oxidation pool, second pond, sterilization pool and clean water basin, said contact-oxidation pool has the air outlet, in the air outlet of said contact-oxidation pool, is provided with the bamboo charcoal filtering layer.
Be provided with sludge sump one in said preliminary sedimentation tank bottom; Also be provided with sewer catch basin in said waste disposal plant side, said sludge sump one is communicated with said sewer catch basin.
Be provided with sludge sump two in said second pond bottom; Said sludge sump two is communicated with said sewer catch basin.
The device of the utility model is embedded in below ground.Position at contact-oxidation pool is provided with venting port, in order to reduce the peculiar smell of discharging gas, goes out to be provided with the bamboo charcoal filtering layer at venting port, so just can not influence the daily life of surrounding resident.In order bottom of device mud to be cleared up more conveniently; The utility model is provided with two sludge sumps respectively in preliminary sedimentation tank, second pond bottom; Side at device is provided with sewer catch basin, and two sludge sumps are communicated with sewer catch basin respectively, make mud all enter in the well; The cleaning personnel only need open well lid can absorb the mud in the well, need not the top cover of opening unit, has alleviated labour intensity greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the vertical view of Fig. 1;
1 is preliminary sedimentation tank among the figure, the 2nd, and anoxic pond, the 3rd, contact-oxidation pool, the 4th, second pond, the 5th, sterilization pool; The 6th, clean water basin, the 7th, sewer catch basin, the 8th, ground, the 11st, sludge sump one, 111st, passage one; The 31st, air outlet, the 311st, bamboo charcoal filtering layer, the 41st, sludge sump two, 411st, passage two.
Embodiment
The utility model is like Fig. 1, shown in 2; Comprise preliminary sedimentation tank 1, anoxic pond 2, contact-oxidation pool 3, second pond 4, sterilization pool 5 and clean water basin 6; Said contact-oxidation pool 3 has air outlet 31, in the air outlet 31 of said contact-oxidation pool 3, is provided with bamboo charcoal filtering layer 311.
Be provided with sludge sump 1 in said preliminary sedimentation tank 1 bottom; Also be provided with sewer catch basin 7 in said waste disposal plant side, said sludge sump 1 is communicated with said sewer catch basin 7 through passage 1.
Be provided with sludge sump 2 41 in said second pond 4 bottoms; Said sludge sump 2 41 is communicated with said sewer catch basin 7 through passage 2 411.
The device of the utility model is embedded in ground below 8.The processing means are to adopt comparatively sophisticated at present biochemical processing contact-oxidation pool.The water quality design variable is 250mg/L by sewage water inlet BOD5, and water outlet BOD5 is that 20mg/L calculates.Having seven partly forms: the ⑴ preliminary sedimentation tank; ⑵ anoxic pond; ⑶ contact-oxidation pool; ⑷ second pond; ⑸ sterilization pool, sterilizing unit; ⑹ sewer catch basin; ⑺ Ventilator Room is formed.⑴ preliminary sedimentation tank: preliminary sedimentation tank is a vertical sedimentation basin, and sewage is 0.3～0.4 mm/second at the upflow velocity of settling tank, and the mud that precipitates is promoted to sludge sump.⑵ anoxic pond: anoxic pond is that denitrogenation processing is provided with; YDT type 3 D elastic filler is set in the pond,, returns nitre attitude ammonia and inferior sour attitude oxygen in the nitrification liquid under the effect of denitrifying bacterium as the carrier of denitrifying bacterium; Be reduced into nitrogen; Reach the purpose of denitrogenation, effective residence time of anoxic pond is 2.5～3.5h, and dissolved oxygen is controlled at≤0.5mg/L.⑶ contact-oxidation pool: sewage carries out biochemical treatment from flowing to contact tank, and contact tank is divided into three grades, and the residence time is 8h; (it is novel elastic filler that the reinforced equipment catalytic oxidation time can reach 8～12h) fillers; Be prone to conjunctiva, do not stop up, the contact-oxidation pool GWR is about 15:1.⑷ second pond: the sewage behind the biochemistry flows to second pond, and second pond is vertical-flow deposition, and surface load is＜1.0m3/m2.h that spoil disposal is promoted to sludge sump.⑸ sterilization pool, sterilizing unit: sterilization pool is by standard: " TJ14-74 " standard is for being not less than 30 minutes, if hospital sewage, sterilization pool can increase the residence time to 1～1.5h.The disinfection way of solid chlorine tablets contact lysis is adopted in sterilization, and sterilizing unit can not continue according to the size of aquifer yield to change and adds dose, reaches to have more water and add medicine, and the purpose of the few dosing of few water outlet needs other sterilizing unit to prepare separately.
