摘要
沿海城市多为软基地区,极易出现地基的变形和不均匀沉降。排水管网系统容易出现管道渗漏、断裂等一系列问题。考虑到软土地区的地基特点,沿海城市污水收集处理应转变思路,将分散型污水处理思路纳入沿海城市污水处理的系统中来,因地制宜地采取集中与分散相结合的模式,不仅可节省投资,而且大大提高污水处理效率。本文分析了沿海城市污水收集处理系统的特点并就分散型污水处理在国内外的应用及优缺点条件进行了阐述。
The coastal cities are usually soft base regions. These cities will easily exist series of problems. These problems include the deformation , non - uniform sedimentation of the base , the infiltration and breakage of the drainage pipelines. The characteristics of base in soft base region decided that there need new thoughts while design the wastewater collection system in these regions. Dispersed wastewater treatment thoughts should be introduced with centralized system. Then the investment will be reduced and the treatment effeciency should be increased largely. The characteristics of the wastewater collection system, the advantages and disadvantages of dispersed wastewater treatment system, the application of dispersed wastewater treatment system in China were illustrated in this paper.
