摘要： The scaled swine farms have been developed rapidly in China since 21st century, which bring serious problem in environmental pollution, especially in winter. In order to s reduce the pollution from intensive scaled swine farms, as well as produce biogas in winter, a technological route was put forward to control the sewage pollution in swine farm by using bio-tank of glass fiber reinforced plastics(GFRP). The experiments in swine farm of FuJian Hua Feng Co. Ltd in Nanping city showed that the developed technology had achieved zero-draining, which was able to solve the pollution problem and produce biogas in winter. The sewage temperature of bio-tank of GFRP increased average 1.18 degrees C more than that of bio-tank of reinforced concrete. And the average biogas-generating rate of bio-tank of GFRP of year 2009 was 0.45 m(3).m(-3).d(-1), which increased 28% more than that of reinforced concrete. The indexes of COD, BOD, SS, NH3-N, and TP for the out-let wastewater of the treatment were 579.1 mg.L-1, 237.7 mg.L-1, 289.8 mg.L-1, 319.4 mg.L-1 and 31.7 mg.L-1, respectively.
