对土地处理法中适合于小城镇的耕作层下土地自然净化系统的成本进行了分析研究。通过对已经运行的几个实际工程的建设投资与运行费用的数据监测与收集,利用SPSS17.0数据处理软件进行拟合,得到处理规模(Q,m3/天)与建设投资(C,万元)之间的关系C=258.130 6Q0.433 7。预测了不同处理规模该系统建设投资与运行成本,并与相同规模其他处理工艺比较。结果表明,耕作层下土地处理系统投资少,运行费用低,在资金短缺的小城镇的污水处理中具有广阔的应用前景。
The cost of land natural purification system under the tillage layer suitable for small towns in the land treatment method was analyzed and studied. Through the monitoring and collection of the data of construction investment and operation costs of several actual projects that have been run, the data are processed with SPSS17.0 data processing software to obtain the data of processing scale (Q, m3 / day) and construction investment (C, ) Relationship between C = 258.130 6Q0.433 7. The system construction investment and operating costs for different treatment scales are predicted and compared with other treatment processes of the same size. The results show that under the tillage layer, the land treatment system has low investment and low operation cost, and has broad application prospect in the sewage treatment of the small town with the shortage of funds.
