通过以上对农村村镇污水水质、水量特点的具体分析、处理工艺经济技术比较以及排放标准的要求，此项设计具有以下几个特点：

 

(1) 该村镇排放污水具有一定的间歇性，水质、水量的不稳定性，需进行一定调节稳定措施。

(2) 污水处理采用工艺必须稳定可靠，处理效果好，运行费用合理，管理维护方便，减少人为因素对处理效果的影响。

(3)在村的各户排污点污水宜尽量集中处理，提高效率，避免分散处理，增加成本与运行管理费用，如管网增加投入较大，可适当增加处理点。

 

排放污水含有机质多、浓度较高且悬浮物含量较大，污水B/C=0.30～0.50,可生化性较好，同时在本工程中出水水质要求较高。

 

因此，我们从投资规模适度、处理效果稳定可靠、管理维护方便、运行费用合理等角度出发，结合在该类污水处理工程方面的实践经验，具体太阳能微动力处理工艺流程，


Through the above analysis of the water quality and water quantity characteristics of rural villages and towns, the comparison of treatment technology and economy, and the requirements of discharge standards, the design has the following characteristics:
(1) The discharge of sewage from the village and town has a certain degree of intermittent, unstable water quality and water quantity, and certain adjustment and stabilization measures are required.
(2) The treatment process must be stable and reliable, the treatment effect is good, the operation cost is reasonable, the management and maintenance is convenient, and the influence of human factors on the treatment effect is reduced.
(3) The sewage treatment at each household sewage point in the village should be concentrated as much as possible, improve efficiency, avoid decentralized treatment, increase costs and operating management costs. If the pipe network increases its input, it can appropriately increase the treatment points.
Sewage discharge contains many organic matter, high concentration and large suspended material content, sewage B/C = 0.30 to 0.50, and has good biochemical properties. At the same time, the water quality requirement is higher in this project.
Therefore, from the perspective of moderate scale of investment, stable and reliable treatment, convenient management and maintenance, and reasonable operating costs, we have combined practical experience in this type of sewage treatment project with specific solar microdynamic treatment processes.
