Method for filtering pig farm wastewater through straw and aerobic composting of filter material and pig manure

The invention provides a method for filtering pig farm wastewater by using straws and aerobic composting of a filter material and pig manure, and the method for filtering pig farm wastewater by using straws comprises the following steps: respectively crushing straws into straw powder with the particle size of 3-2cm, and constructing the straw powder into a filter layer with the volume weight of 0.13-0.17 g/cm < 3 > to treat pig farm wastewater. According to the method for filtering pig farm wastewater through straw and aerobic composting of the filter material and pig manure, the problems that after crops are harvested in the northern area, the total amount of straw is large, and treatment is difficult can be solved; meanwhile, a high-quality auxiliary material is provided for aerobic composting of the breeding manure, secondary environmental pollution caused by random stacking of the filter material and the manure is reduced, and the resource utilization efficiency is improved. 本发明提供了一种秸秆过滤猪场废水及滤料与猪粪好氧堆肥的方法，
