Abstract

The aim of this study was to expand the recycling direction of chicken farm resources and create a new waste recycling chain of chicken farm, the chicken farm sewage (mainly domestic sewage, including a small amount of fecal urine) for biological circulation pretreatment, and the treated water into the biological purification pool, and then used for fish breeding and chicken protein feed cultivation. The test results show those: 1. The water could meet the surface water and above water standards, ammonia nitrogen and phosphorus, the treated water, after the biological purification tank, does no harm and could promote the growth of fish; 3. Closed water circulation after 15 days, the biological circulation tank is ideal, the highest value of ammonia nitrogen content is only 0.023mg/L; 4. The purple duckweed cultivated by the circulating water replaces 8% of the soybean meal in the feed.
