So the effect of pollution improvement is affected, at the same time investment benefit is not fully made well. Aiming at the above problems occurred during the improvement of water environment pollution, based on the general analysis of current water environment pollution situation and cause of pollution by the instance of the water environmental pollution improvement in the centre town of Chengdu City, the article puts forward the reasons of water environment pollution of most cities: wastewater collection is insufficient because of delaying of pipe net construction; capability of sewage treatment is inadequate; manage measure is not regular because of management not according to laws and laws not strictly executed; investment channels of pollution implement is unitary.

通过对成都市中心城水环境治理实施方案的研究，对如何与城市建设相结合来进行水环境污染治理提出以下几点看法：①应合理划分流经城市水体的功能区域和正确确定水环境治理目标一些设想；②必须有科学、合理、全面、可操作性强的城市排水规划；③建设、完善污水收集系统，提高污水收集率，加快城市污水处理厂建设，提高污水处理能力；④对中心城河道按防洪、截污、环卫、绿化、景观的要求进行全面整治；⑤治污资金的筹措应从单一的政府投资模式向多元化的融资渠道发展；⑥制定、完善相应的法律、法规、制度以及工程建设管理措施。

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。

The municipal drainages referred in these measures mean the pipes and nets, canals, sewage pump houses, sewage factories, the final disposition facilities and relevant facilities of sewage and sullage which are used to accept and transfer city sewage, industrial waste water and rainwater.

It was emphasized that GB3838-2002 not only need to pay attention to the full treatment of wastewater and rainwater but also the proper disposal of treated wastewater which meet the national discharge standard GB18918-2002 but still contain significant amount of pollutants if compare with the national surface water quality standard GB3838-2002. To the brooky region of Jiang-Zhe Plain, the discharged pollutant loads still significantly exceed the environmental capacity of the receiving waters even if all treated wastewater meet the first grade B limits of GB18918-2002, and the water pollution problem still cannot be really eliminated.

通过比较分析，我国现行的城镇污水处理厂污染物排放标准GB18918-2002和地面水水质标准GB3838-2002，明确提出，相对于这一区域的地面水环境质量而言，不但雨污水必须得到充分有效的净化处理，达标排放的污水中也仍然含有总量不容忽视的污染物质；对于江浙平原河网地区，即使全部城市污水都达到GB18918-2002中一级B的要求，排放的污染物负荷仍然会明显超过受纳水体的环境容量，水污染问题仍然难以真正消除；达标处理水的处置与利用问题值得特别的关注与探讨。

Under this background, this article systematically demonstrates the summarized theory and method of sewage disposal and retrieval and utilization, the article take the waste water through film production as the research object, take the ceramicite as filling, adopt with the process of biological aerated ceramicite filter, discussing the feasibility of disposal of the waste water through film production as well as realizing the purpose of sewage First of all, this article briefly introduced the traditional process of sewage disposal and state of development; introduces the course of Lucky film company's sewage disposal and current situation; analyzes emphatically the history of material of filter, current situation and development as well as the domestic application achievement of biological aerated filter and existing problems.
