Paper Title:
Comprehensive Sewage-Treating Technology Using Bio-Tank of Glass Fiber Reinforced Plastics on Intensive Scaled Swine Farm
  Abstract

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°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 m3·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-1and 31.7 mg·L-1, respectively.
