titleOfInvention | A kind of adsorption purification method of livestock and poultry wastewater |
abstract | The invention provides a method for adsorption and purification of livestock and poultry wastewater. The method firstly pretreats the livestock and poultry wastewater, then adds mullite powder, and after mixing, anaerobic fermentation is carried out to generate biogas and treatment liquid, and the biogas is used for subsequent use and treatment. Add adsorbent to the liquid, stand, and separate solid and liquid to obtain effluent and sludge. The former is directly discharged, and the latter is mixed with medicine and dried for external use, which can effectively reduce the chemical oxygen demand (COD) in livestock and poultry wastewater. ) concentration, ammonia nitrogen (NH 3 ‑N) concentration and total phosphorus (TP) concentration, and have broad application prospects. |
