The nutrient in water is reduced, for mucus shape film layer to bacterium, primary sound animal and metazoa, no oxygen animalcule, bacterium, primary sound are dynamic
Object and metazoa largely consume the nutrition inside adsorption layer, and bacterium, primary sound animal and metazoa voluntarily inactivate.
Preferably, the microorganism of the biological film inner layer cannot get sufficient nutrition and enter endogenous metabolism, form it into
Waste material layer；Microorganism loses the adhesive capacity between adsorption layer not in secreting mucus matter, gas of the waste material layer in sewage
Under the action of bubble disturbance and hydraulic shear so that blocked up waste material layer is detached from carrier, and absorption surface can rapidly have been grown newly
Waste material layer continues to purify sewage.
Preferably, it is discharged one end water sampling through biomembrane for described pair, is detected in water using COD ammonia nitrogen total phosphorus tachymeters
The content of COD, the content to judge the organic matter in water outlet judge whether sewage disposal reaches whether within critical field
Mark.
Compared with prior art, beneficial effects of the present invention are as follows：
1. adaptable：The cell in biomembrane is embedded in due to population effect, has stronger antitoxin sexuality, specific ionization thin
The antitoxin sexuality of born of the same parents is eager to excel 50~500 times, therefore biomembrane changes with stronger adaptability water quality.
2. the aerobic decomposable process for supporting bacterium well of absorption layer surface can be divided into two stages：First stage mainly will
Organic matter is converted into CO2、H2O、NH3Deng；Second stage, mainly NH3It is converted into NO2And NO3, with aerobic method treated sewage,
Peculiar smell in water removal can drop, and it is shorter to handle required time.
3. microorganism treatment dirt-removing power is up to 90% or more, water quality that treated is good, and the COD in water is total by COD ammonia nitrogens
Phosphorus tachymeter detects, and the COD in water is significantly reduced, and can be exhausted directly in the Nature.
