Anoxic pond, anoxic pond can carry out denitrification using the organic matter carbon source in the nitrate and water inlet brought into the mixed liquor to flow back,
NO2-, NO3- are reduced into N2 and reach denitrification in making into water, degradation of ammonia nitrogen value while organics removal；To make A grades of lifes
Dissolved oxygen control uses submersible agitating, the filler of A grades of biochemistry pools vertical using novel elastic in 0.5mg/l or so, pond in object pond
Body filler is highly 3.0 meters；
（4）, O grades of biological tanks：For sewage after anoxic pond is handled, gravity flow enters contact-oxidation pool, hence into the catalytic oxidation stage,
Enter Aerobic Process for Treatment, contact-oxidation pool is to have the biological treatment device of active mud concurrently based on a kind of biofilm, pass through offer
Oxygen source, the organic matter in sewage make water quality be purified by Institute of Micro-biology's absorption, degradation；
（5）, MBR reactors：MBR reactors are that one that membrane technology is combined with the biochemical reaction in sewage disposal is emerging
Technology, also referred to as membrane separation activated sludge process are filtered the water containing dirt in biochemical reaction tank, realize mud-water separation；One
Aspect, film have retained the microorganism in reaction tank, and the activated sludge concentration in pond is made to greatly increase, and reach very high level, make
The biochemical reaction of degradation of contaminant carries out rapider more thorough, on the other hand, due to the high filtering precision of film, ensure that water outlet
It is as clear as crystal, obtain the production water of high quality；By the waste water of deep oxidation, to reach stable or higher discharge standard, carry out
Further advanced treating；
（6）, sludge-tank：Clarifier sludge is promoted to sludge-tank with air and carries out room temperature digestion, and the supernatant of sludge-tank is back to
It is reprocessed in contact-oxidation pool, excess sludge is seldom after digestion；Method for cleaning can use inspection hole of the fecal suction truck from sludge-tank
It stretches into sludge bottom and carries out suction outward transport；
（7）, sterilization pool：Sterilization pool time of contact is 30 minutes, and disinfection uses disinfection by chlorine dioxide；Dosage is 4-6mg/L,
Processing water after biochemistry carries out disinfection processing again.
Preferably, the step（1）It is 10mm that middle grid, which uses stainless steel steel, grizzly bar gap,.
Preferably, the step（4）In biological contact oxidation pond provide air sources, gas using 2 HC rotary blowers
Water is than 20：1, use elastic filler for the carrier of biomembrane, pack length 2000mm, diameter 150mm；Aerator uses rubber membrane
Chip aerator.
Compared with prior art, the beneficial effects of the invention are as follows：Present invention process flow is succinct, flexible, and equipment arrangement is closed
Reason, it is compact-sized, take up an area less, is beautiful, existing sewage disposal needs can not only be met, and economic and environment-friendly.
