污水回用系统改造与综合经济分析

本文根据地下水位不足，水质恶化，水费及排污费大幅度提高的实际情况，提出了对外排水进行回收深度处理工艺与改造方案，以用于工业冷却、循环系统补水及工艺用水，并对减少企业用水设备因堵塞结垢等造成的损失和节约新水水费、减少排污水费以及运行成本进行综合经济分析。

Comprehensive Economic Analysis and Improvement of Sewage Reuse System

Because that underground water level was lower, water quality was dete- riorated, and water expenditure and sewage discharge expenditure were increased significant- ly, this peper proposed a recovery technology and an improvement plan for commercial cool- ing, recycly system supplement water and process water. It also analyzes economically on loss caused by blockage and scaling of equipments, saving of fresh water, decreasing sewage discharge expenditure and operation cost.
