The product description
/instructions
VOC biological treatment is the use of microbes in the waste gas as its life including moving energy or other nutrient units, the metabolism of explanation, transformed into simple inorganic compounds (carbon dioxide, water etc.) and cell components. Almost all organic and inorganic pollutants can be transformed. At present, the gaseous pollutants suitable for biological treatment mainly include ethanol, mercaptan, phenol, cresol, indole, fatty acid, acetaldehyde, ketone, carbon disulfide, ammonia and amine.
Process description
Technical principle
Gas liquid absorption consists of microbes, nutrients and water microorganisms, exhaust gas have set as microbial life energy or other nutrients, metabolic explanation, transformed into simple carbon dioxide and water etc.. The mixed liquid of the waste gas is absorbed to carry out aerobic treatment to remove the pollutants absorbed in the liquid. Its typical forms include spray tower, bubble tower and perforated tower, etc..
Process flow chart:
Biological suspension self absorption chamber and a top spray, the exhaust gas in the organic matter and oxygen concentration in the liquid phase, the mass transfer, absorption of biological suspensions of organic matter in the exhaust gas flow regeneration reactor (activated sludge), by air oxygen regeneration. The absorbed organic matter is converted to carbon dioxide and water by microbial oxidation, which is finally removed from the liquid phase by the activated sludge suspension in the regeneration tank.
The device is mainly composed of five parts: the exhaust gas collection system, the exhaust gas pretreatment system, the biological absorption tower, the regeneration tank and the automatic control system.
Product features
High purification rate;
Temperature, PH, nutrient balance and metabolite removal can be adjusted by the water in the reactor, so the system is easier to control;
After the degradation of organic matter can be washed out;
No two pollution, low investment and operating costs;
Application scope
Can be used for the treatment of petrochemical, pharmaceutical, feed and fertilizer processing plants, livestock farms, chemical factory, leather factory, pulp factory, sewage pumping stations, sewage treatment plants, all kinds of food additives, paint factory, leather processing, optical materials and automobile manufacturing industry of waste gas, odor, odor and other pollution problems.
