1. Chicken excreta, containing carbon, nitrogen, phosphorus and other pollutants, as reflected in the laboratory indicators of COD, BOD, SS, ammonia nitrogen, total nitrogen and total phosphorus and other items;
2. Chickens drop feathers, feed residues and other items containing carbon, nitrogen and phosphorus and other pollutants, as reflected in the laboratory indicators of COD, BOD, SS, ammonia nitrogen and total phosphorus and other items;
3. The above two types of pollutants fermentation will produce gas and acid production. Indicators for COD, BOD, SS, ammonia nitrogen and total phosphorus and other items;
3, the above two types of pollutants after fermentation, will produce gas and acid production, the gas produced methane, ammonia, hydrogen sulfide, etc., will pollute the atmosphere; acid produced amino acids, fatty acids, etc., will reduce the acidity of the drainage water, embodied in the laboratory indicators for pH is too low, and some of the acid produced will be volatilized to produce a bad smell.
In summary, the chicken farm pollution of the environment is reflected in the atmosphere, water and solid waste in three aspects. Definitely pollute the water.
