鉴于目前排污口流量测验手段的不足,尝试采用电化学的方法进行排污口流量测量。电导率法测流是在测验河段的上游施放已知浓度的氯化钠溶液,由于施放溶液的稀释扩散作用和水流的紊动混合,经过一定的时间后,在下游断面达到充分混合,该断面作为取样断面。在取样断面施测水的电导率,即可以推算出排污口废污水的流量。将电导率法与常规流量测验方法容量法进行比对,试验证实本方法简便易行,适应性强,可以在实际工作中推广应用。
In view of the current lack of sewage outlet flow test means, try to use the electrochemical method of sewage outfall flow measurement. Conductivity method is to measure the river upstream of the test release of sodium chloride solution of known concentration, due to the dilute diffusion of the solution and the turbulent mixing of water flow, after a certain period of time, in the downstream section to achieve full mixing, the Section as a sampling section. Measured in the sampling cross-section of the water conductivity, which can be estimated sewage outfall sewage flow. The conductivity method is compared with the capacity method of the conventional flow test method. The test shows that the method is simple and easy to use, adaptable and can be popularized and applied in practical work.
