Wall enters apart from upward 2 centimeters of import in stripping tube downwards, and tracheae outlet is arranged upward in stripping tube, through the 9th area 11
A filtered sewage part is back to the secondth area of septic tank 4 by stripping tube, and then enters third area 5 and the 5th area 7 and carry out
Anoxic denitrification processing, reduces total nitrogen content.
Shown U-tube 15 is symmetrical in corresponding partition board both sides, and the size and place height of two U-tubes need to keep one
Cause, U-tube bottom away from the upward 1/10 inner cylinder height in institute's fixed baffle bottom end at, U-tube height be inner cylinder height 1/5~2/5.
When sewage purification, initially enters the firstth area of septic tank 3 and the secondth area of septic tank 4 and carry out anaerobic fermentation and precipitation, Gu
Compound is decomposed in bottom of pond, and upper layer hyrate body enters third area 5 and the 5th area 7 and carries out denitrification, and third area 5 and the 5th area 7 have
Floating stuffing makes sewage be come into full contact with microorganism, converts nitrate nitrogen in water to nitrogen by the pneumatic immixture of U-tube 15
Gas, and further degrade to organic matter；6th 8, the 7th 9, Section Eight 10 be aerobic environment, microorganism adheres on soft-filler
Growth, aeration plate 17 provide oxygen, carry out nitration reaction, and further degrade to organic matter, the 9th area 11 and 12 heap of the tenth area
Filtrate is put, 11 sewage of the 9th area flows through from top to bottom, and a filtered sewage part flows back into septic tank by stripping tube 19
Two areas 4 are reprocessed, and a part carries out secondary filter through the tenth area 12, are finally discharged by outlet.Water outlet can be used for flushing the toilet, fill
Irrigating also can directly permeate the ground；Microorganism mostly exists with biological form membrane in the purification tank, therefore sludge output is small, sludge clearing week
Phase is longer, but septic tank domestic demand is periodically drawn clearly.
The above basic principles and main features that detailed description of the preferred embodimentsthe present invention has been described.The technical staff of the industry should
Understand, protection scope of the present invention is not restricted to the described embodiments, any variation expected without creative work or
It replaces, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with claims institute
Subject to the protection domain of restriction.
