Abstract
The invention relates to a domestic sewage treatment technology, and in particular relates to a rural domestic wastewater treatment process. After large impurities are removed by virtue of fine screen of a screen well, sewage enters into a regulating tank, and a perforated aerator pipe is arranged inside the regulating tank for aerating and stirring, so that the sewage is homogenous in quality and quantity; then the sewage automatically flows into an anaerobic-aerobic tank (A/O); due to the functions of aerobic and aerobic microorganisms, organic matters are decomposed into CO2 and H2O so as to remove most organic matters, and nitrification liquid from the tank O returns into the tank A to remove ammonia nitrogen; water discharged from the tank O automatically flows into a secondary sedimentation tank to remove suspended solids; and water from the secondary sedimentation tank is discharged on standard. The wastewater treatment process disclosed by the invention is high in removal efficiency, stable in operating performance and low in treatment cost.
Description
Technical field
The present invention relates to sanitary sewage disposal technology, specifically relate to rural domestic waste treatment process.
Background technology
Domestic sewage in rural areas comprises the drainings such as washing, shower, kitchen cooking, ight soil and flushing thereof.Due to the imbalance of rural economic development, the amount of various places domestic sewage in rural areas and matter also differ comparatively large, generally speaking, domestic sewage in rural areas have wide dispersion, source many, increase soon, sewage complicated component, water quality and the water yield change large feature.The discharge approach of existing domestic sewage in rural areas mainly directly spills earthward, enter river course nearby or enter river etc. by water drain.In draining, Problems existing is mainly manifested in: one is during many newly constructed houses and old room sanitary facility are transformed, although have three compartment septic tanks, there is no drain facility, but rely on soil permeability, though this method is easy, severe contamination underground water around; Even if but have water exhaust system, the overwhelming majority is also drainage system, and generally adopts open drainage, and owing to not having science, reasonably planning, a large amount of uses of agricultural chemicals in addition, feces of livestock and poultry flow into irrigation canals and ditches with rainwater, and severe contamination life in the countryside environment; Three is that rural area often has feed ditch to run through wherein, and along with every family generally uses water-closet, various sewage is unprocessed enters feed ditch in a large number, pollutes quite large to agricultural irrigation water.In order to the fine rural area of promoting a conservation culture, need process country sewage.
Current country sewage principal pollutant are COD, BOD, SS, ammonia nitrogen, total phosphorus etc., and effluent quality is given an written reply by environmental protection competent authorities and performed " integrated wastewater discharge standard " (GB8978-1996) standard.
Summary of the invention
Technical problem to be solved by this invention is to provide the rural domestic waste treatment process that a kind of clearance is high, operating performance is stablized, processing cost is low.
For solving the problems of the technologies described above, the invention provides following technical scheme: rural domestic waste treatment process, comprises the following steps:
A. rural domestic waste is introduced into grille well, filters through mechanical fine fack, and in the lower waste water of filter, large granular impurity forms grid slag, and grid slag concentrates regularly outward transport;
B. equalizing tank being introduced in the water outlet of steps A, through the boring aeration pipe that equalizing tank is built-in, aeration agitation, is that sewage homogeneous is all measured;
C. A/O pond is introduced in the water outlet of step B, gas blower provides sufficient air for O pond, under double oxygen, aerobic microbiological effect, is CO by organic substance decomposing
2and H
2o, removes most of organism; A pond is gone back in the nitrification liquid drainage of O pond, removes ammonia nitrogen;
D. second pond is introduced in the water outlet of step C, remove suspended substance, meanwhile, in second pond, a mud part is back to A pond reprocessing, and another part drains into sludge sump process, regularly aspirates outer row to excess sludge in sludge sump;
E. discharged wastewater met the national standard.
The beneficial effect that the present invention compared with prior art has is: for rural domestic waste, adopt the combination process of A/O, this combination process can also remove ammonia nitrogen while organics removal, tool has the following advantages: 1. biological contact oxidation process can adapt to the organic sewage of different concns, to variation water quality, there is stronger shock resistance, the required residence time (HRT) is shorter, and the clearance such as SS, BOD, COD and ammonia nitrogen is high.2. operating performance is stablized, and produces surplus sludge volume few, reduces working cost.
Accompanying drawing explanation
Fig. 1 is present invention process schema.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Known with reference to Fig. 1, rural domestic waste treatment process, comprises the following steps:
A. rural domestic waste is introduced into grille well, filters through mechanical fine fack, and in the lower waste water of filter, large granular impurity forms grid slag, and grid slag concentrates regularly outward transport;
B. equalizing tank being introduced in the water outlet of steps A, through the boring aeration pipe that equalizing tank is built-in, aeration agitation, is that sewage homogeneous is all measured;
C. A/O pond is introduced in the water outlet of step B, gas blower provides sufficient air for O pond, under double oxygen, aerobic microbiological effect, is CO by organic substance decomposing
2and H
2o, removes most of organism; A pond is gone back in the nitrification liquid drainage of O pond, removes ammonia nitrogen;
D. second pond is introduced in the water outlet of step C, remove suspended substance, meanwhile, in second pond, a mud part is back to A pond reprocessing, and another part drains into sludge sump process, regularly aspirates outer row to excess sludge in sludge sump;
E. discharged wastewater met the national standard.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
