Swine production has been one of the key agricultural industries in Taiwan for a long time. Over 6 million hogs were produced this year (2013), and they generated around ten million tons of solid sewage per year, an amount equivalent to the capacity of the Sun-Moon Lake. More importantly, the COD of effluent is often up to 2,000mg/L or more even after treatment. Large amounts of swine waste have been causing environmental concerns such as greenhouse gas, odor emission and potential nutrient contamination to surface and ground waters. The water pollution problem could be effectively improved by applying the new method —“Compound Microbial Flora” without requiring to change the sewage treatment facilities. Morever, the application cost is low and the operation procedure is easy for farmer. The following water quality could be obtained after continuous operation of the “Compound Microbial Flora” : SS(~75 mg/L)、OIL(~2.0 mg/L)、BOD(~160 mg/L)、COD(~320 mg/L) and P(~10 mg/L), and the roughly decontamination efficiency would be 90%, 80%, 90%, 90% and 70%, respectively. It can also reduce the odor of chicken coop or pigsty very significantly by proper use of “Compound Microbial Flora”. The concentration of NH¬3 and H2S is decreased from 36.9 ppm to ND and from 172.4 ppb to ND, respectively, after applied the method in outdoor of chicken coop. Through experiments on the the chicken coop and pigsties, it has been proven that “Compound Microbial Flora” is effective on swine wastewater treatment and deodorizing. And most importantly, it is low costed and easy to operate.
