Method for controlling water quantity and water quality in operation period after sewage intercepting system is built
The invention discloses a method for controlling water quantity and water quality in an operation period after a sewage intercepting system is built. The method comprises intercepting wells, a flow limiting device, a sewage intercepting branch pipe, a sewage intercepting main pipe and a water quality measuring unit, wherein confluence sewage enters the sewage intercepting branch pipe through the intercepting well, the sewage intercepting branch pipe is connected with the sewage intercepting main pipe, the tail end of the sewage intercepting main pipe is connected with a sewage treatment plant,the sewage treatment plant is provided with a water quality detection unit for verifying the flow-limiting effect. According to the method, different plugging schemes are designed by investigating and observing the confluence pollution degree of each intercepting well, then the reasonable flow limiting combination is operated for a certain period of time, different operation conditions are obtained, finally the optimal condition is obtained, the highest working condition of continuous multi-day average values of sewage plant detection indexes (cod value, ammonia nitrogen value and total phosphorus value) is taken as the optimal working condition, and under the condition that the treatment capacity is not changed, the higher the concentration value of the treated intercepted sewage is, theless the overflow pollution of an intercepting system is, the higher the treatment efficiency of a sewage treatment plant is, the better the emission reduction effect is, and the higher the environmental benefit is.
本发明公开了一种污水截流系统建成后运行期间水量水质控制方法，包括截流井、限流装置、截污支管、截污干管和水质测单元，所述合流污水经截流井进入截污支管，截污支管与截污干管相连，截污干管末端与污水处理厂相连，污水处理厂设置水质检测单元验证限流效果，本发明通过调查观测各个截流井的合流污染程度，设计不同的封堵方案，然后对合理限流组合进行一定时间运行，得出不同运行工况，最终取得最优工况，以污水厂检测指标(cod值、氨氮值、总磷值)连续多日平均值最高工况为最优工况，处理量不变的情况下，处理的截流污水浓度值越高，截流系统溢流的污染就越少，污水处理厂处理效率提高，减排效果提高，环境效益提高。
