Study on the Biogas Slurry Purification of Microorganism and Chlorella and the Effect of Fish Culture
摘要
Abstract
Biogas slurry was purified and treated as a resource by microorganism (the complex bacteria of photosynthetic bacteria and bacillus subtilis)and Chlorella,and then changed to be aquaculture water.Three groups of tilapia, bighead, silver carp, catfish, grass carp with different proportion were put into the fishponds for researching the effects of purification and fish culture on biogas slurry by microorganism and Chlorella. The results showed that microorganism and Chlorella could purify the biogas slurry effectively and kept the fishpond water quality on healthy level for long time. The indicators of fishpond water quality in the culture time were that DO 6.1~10.6 mg·L-1, pH 7.8~8.9, NH4+0.28~0.72 mg·L-1,NO2-0~0.01 mg·L-1,PO42-24.5~70.0 mg·L-1. The group got the higher production value with the proportion of 16% tilapia, 2% bighead, 2% silver carp, 80% catfish. Biogas slurry can be purified by mi-croorganism and Chlorella effectively and has good effect on culture.关键词
