Specific embodiment

For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing Unrestricted feature description is as follows:

As shown in Figure 1, a kind of buried under earth type sewage treatment equipment, is connect by conditioning tank 100, hydrolysis acidification pool 200, biology It touches oxidation pond 300 and secondary settling tank 400 is constituted, be that purification main body can be had using contact oxidation method biochemical processing with biomembrane The substances such as BOD5, COD, the NH3-N contained in effect removal sewage, are widely used in the life of the places such as house urban district, hospital, military camp The processing of sewage.

Water inlet pipe 110 is set in the one side wall of conditioning tank 100, and setting intercepts big between water inlet pipe 110 and conditioning tank 100 Submersible sewage pump 130 is arranged in the grid maker 120 of grain suspended matter, 100 bottom of conditioning tank, and setting is connected with submersible sewage pump 130 in conditioning tank 100 First pipe 140, first pipe 140 passes through and conditioning tank 100 and protrudes into hydrolysis acidification pool 200.

Comprehensive wastewater enters back into conditioning tank 100 after intercepting bulky grain suspended matter by grid maker 120, and conditioning tank 100 plays The effect of balanced water quality, regulating pondage.

Hydrolysis acidification pool 200 for sediment fraction pollutant and is detested the activated sludge periodically from secondary settling tank 400 Oxygen digestion, hydrolysis acidification pool 200 is interior to arrange the first biologic packing material 210, and 200 bottom of hydrolysis acidification pool is set as hydrolysis acidification pool First micropore aeration pipe 220 of 200 oxygen supplys, the second pipe 230 that the interior setting of hydrolysis acidification pool 200 is communicated with secondary settling tank 400, water Solution acidification pool 200 is communicated with biological contact oxidation pond 300.

Hydrolysis acidification pool 200 can intercept the fine suspension in water, decompose a part of organic matter, reduce in subsequent processing Organic loading, precipitated phase work as some of the contaminants；Hydrolysis acidification pool 200 stores the work that secondary settling tank 400 periodically promotes reflux simultaneously Property sludge and anaerobic digestion is carried out to it, to reduce amount of sludge, reduce outward transport expense.

Biological contact oxidation pond 300 is used to decompose the organic matter in water, bio-contact oxidation by biological contact oxidation process The second biologic packing material 310 is arranged in pond 300, the second micropore aeration pipe 320 is arranged in 300 bottom of biological contact oxidation pond, and biology connects Touching oxidation pond 300 is communicated with secondary settling tank 400.

Biological contact oxidation pond 300 decomposes the organic matter in water with microbe films osculation oxygenation method.Biological contact oxidation process is A kind of biological effluent treatment derived from from biofilm.Sewage is in contact with biomembrane in the process, in biomembrane Under the action of upper microorganism, it can make to purify the sewage, therefore also known as " submerged bacteria filter ".

This method provides the oxygen amount that Institute of Micro-biology needs using identical with aeration tank aeration method, and rise stirring with mix Effect, while adding filler in aeration tank, and for attached growth of microorganisms, therefore, also known as contact aeration process is a kind of Jie It is the biofilm of active sludge feature in activated sludge process and the biological treatment of biofilter between the two, it The advantages of having both the two.

Secondary settling tank 400 is for precipitating the activated sludge from biological contact oxidation pond 300 and giving off clear water, secondary settling tank Sludge reflux pump 410 is arranged in 400 bottoms, and second pipe 230 stretches to 400 bottom of secondary settling tank and is connected with sludge reflux pump 410, The effluent weir 420 of side setting discharge clear water of the secondary settling tank 400 far from biological contact oxidation pond 300.

Specifically, the activity that setting guide channel 430 is used to that biological contact oxidation pond 300 to be guided to come in secondary settling tank 400 Sludge.It is in order to which the activated sludge from biological contact oxidation pond 300 preferably enters secondary settling tank 400 that guide channel 430, which is arranged, Bottom precipitated, be not easy to generate in secondary settling tank 400 muddy, keep the clear water of discharge more clear.

Specifically, also setting up sterilization pool 440 in secondary settling tank 400, effluent weir 420 is communicated with sterilization pool 440.Secondary settling tank 400 The activated sludge come in by biological contact oxidation pond 300 is precipitated, activated sludge is periodically promoted by sludge reflux pump 410 and is back to water Acidification pool 200 is solved, the sterilized pond 440 of the clear water of the generation in secondary settling tank 400 is discharged after disinfecting from effluent weir 420.

Specifically, submersible sewage pump 130, sludge reflux pump 410 are electrically connected with external power supply, features simple structure easy to use.

A buried under earth type sewage treatment equipment full set in the utility model is embedded in underground, and effect on environment is small, can be effective The sundries and organic matter in water removal are removed, national standard is fully achieved in water outlet.It is usually not necessarily to personal management, technical performance is stablized, fortune Row is safe and reliable.

Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap Within scope of patent protection contained in the utility model.
