Description
Technical field
The present invention relates to dirt, wastewater treatment.Refer in particular to a kind of biological sewage treatment device and method that can change microbial quality of various high densitys, supersalinity, high ammonia nitrogen, difficult degradation, poisonous and harmful Industrial Wastewater Treatment.
Background technology
Biological treatment is to utilize microbial metabolism effect, is that organism in dirty, waste water and inorganic micro-nutrients are converted into and stablize harmless material.Biological treatment is by whether oxygen supply is divided into aerobic treatment and the large class of anaerobic treatment two, and the former mainly contains two kinds of activated sludge process and biomembrance process, and the latter comprises various anaerobic digestions.
Activated sludge process is the dirt take active sludge as main body, the main method of biological wastewater treatment.In dirt, waste water, constantly inject air, maintain in water and have enough dissolved oxygens, through after a period of time, in dirt, waste water, generate a kind of flocs unit.This flocs unit is made up of prolific microorganism, is easy to precipitate and separate, and dirt, waste water are clarified, and Here it is " activated sludge process ".Microorganism and organism form the major portion of active sludge, account for the more than 70% of whole active sludge.The water ratio of active sludge, generally 98% ~ 99%, has very strong absorption and the ability of degradation of organic substances, can reach and process and purify object dirty, waste water.Active sludge ratio juris image saying: microorganism " has eaten up " organism in sewage, dirty like this, waste water has become clean water.Typical activated sludge process is made up of aeration tank, settling tank, sludge reflux system and excess sludge removal system.
Biomembrance process is the baroque microorganisms symbiosis body being fixed on specific support by adhering to.With respect to activated sludge process, microbe population contained in unit volume microbial film is more, specific surface area is larger.
Anaerobion processing is under the condition of anaerobic, utilizes a kind of biological treatment of amphimicrobe and anerobe decomposing organic matter.
On modern dirt, method of wastewater treatment, be mainly according to character and microbial growth rule dirty, waste water, suit measures to local conditions to select above-mentioned different technique, and the novel process of each unit is organically combined, form a complete treatment system.
General A/O, the A of adopting in the domestic high density in industries such as petrochemical complex, oil refining, coking, textile printing and dyeing, synthetic leather, pharmacy, agricultural chemicals, food, fine chemistry industry, Coal Chemical Industry, papermaking, supersalinity, high ammonia nitrogen, difficult degradation, poisonous and harmful wastewater treatment
