Because of the development of chemical fabric, rising of artificial technology and making progress of technology, which are the reasons of making a amount of the difficult biochemistry degrade of PVA serosity, artificial silk alkali solve matter and new-type auxiliary thing to enter into dyeing wastewater in recent years, and COD rises 2000-3000mg/L.

近年来由于化学纤维织物的发展，仿真丝的兴起和印染后整理技术的进步，使PVA浆料、人造丝碱解物、新型助剂等难生化降解有机物大量进入印染废水，使COD浓度从原来的数百毫克每升上升到2000-3000mg/L，从而使原有生物处理系统COD去除率从70%下降到50%左右，甚至更低，传统的生物处理工艺受到严重挑战，作为纺织品的生产，其生产过程关系到人们生活的大环境。

By experimenting with solid-liquid separator in the treatment of sewage before it is discharged on three large scale pig farms, we come to the conclusion that solid-liquid separator is effective in gathering dung sullage, with about 2.9 t/h and the water content less than 55%. The average rates of removal of TS, COD, and BOD are 82.5%, 77.5% and 73.5%, respectively. ByKey words: FZ-12 solid-liquid separator; large scale pig farm; sewage treatment

为了了解FZ-12固液分离机前处理效果，对3个规模化猪场进行污水前处理试验，结果表明，FZ-12固液分离机能有效地收集粪渣，平均收集量为2.9t／h左右，粪渣含水率〈55％，对猪场污水的TS、COD和BOD平均去除率分别达到82.4％、77.5％和73.5％，应用该机处理猪场污水，增加相关投资约人民币5.3万元，收集的粪渣出售后，扣除运行成本，年可增收税利约人民币4.5万元，投资回报率达84.9%，约1.18年可收回投资，因此，应用FZ-12固液分离机处理猪场污水，具有广阔的应用前景。

"In terms of fishing and farming, global warming has meant there are better conditions for the livestock. There are increased cod fisheries which will also have a significant effect on our economy.
