摘要
提出治理水污染需要在现代农业背景下重建城乡之间物质循环系统,可通过"沼气推广工程"对农村污染源进行无害化处理,通过"沼气试点工程"对城市生活污水进行资源化利用,通过"沼气净化工程"对小城镇污水进行达标处理,通过"沼气回收工程"使企业有机污染物变废为宝,最后引进自然生态系统进化工程,使水体达到充分净化。
A material cycle that links urban and rural areas in order to control water pollution is proposed for modem agriculture. It can be achieved through bio-gas promotion projects in the countryside that make the source of pollution harmless, bio-gas pilot projects in cities that utilize sewage as a resource, bio-gas purification projects in towns that force discharged sewage to conform to national standards, bio-gas recycling projects that recycle the organic contaminants, and utilization of the natural eco-system to purify water.
