人工快渗技术在我国农村地区水污染治理中的应用研究

概述了我国农村地区水污染现状、排放特征、主要处理工艺及其优缺点,在对人工快渗系统工艺原理和污染物去除机理深入分析的基础上,总结归纳了人工快渗工艺的技术经济优势,并结合技术的工艺改进和完善,探讨了人工快渗技术的适用性。然后结合深圳市白花洞村、四川省绵阳市北川县及北京昌平区农村工程实践,分析了人工快渗技术在村级分散型污水处理工程中的实际运行效果。理论研究和工程实践均表明:人工快渗技术及其改进工艺组合系统具有工艺简单、建设运行成本低、污染物去除效率高、出水效果好等特点,可有效地解决目前农村地区因受到资金、技术、人才等因素限制造成的污水处理能力低的问题,是一项十分适合我国农村地区的污水处理技术。

APPLIED RESEARCH ON WATER POLLUTION TREATMENT BY CONSTRUCTED RAPID INFILTRATION TECHNIQUE IN CHINA RURAL AREAS

It is summarized the current situation,emission characteristics,advantages and disadvantages of the main treatment process of water pollution in rural areas.Based on in-depth analysis of the principles constructed rapid infiltration and pollutant removal mechanism,the technical and economic advantages of constructed rapid infiltration techniques are summarized.It is also discussed the applicability of constructed rapid infiltration techniques,in combination with the process of improvement and perfection,then combined with engineering practice,it is analysed the actual effect of rapid infiltration in decentralized village sewage treatment works in villages.Theoretical study and engineering practice show that constructed rapid infiltration techniques and its improved technology systems,have the advantages of simple process,low cost in the process of construction and operation,high pollutant removal efficiency,good water quality of the effuents,can effectively solve the problem of low sewage treatment capacity in rural areas due to funding,technology,personnel and other limited factors,is a very suitable sewage treatment technology for China’s rural areas.
