Sewage discharge total amount monitoring and sampling device

Abstract

The invention relates to the technical field of sewage monitoring, and discloses a sewage discharge total amount monitoring and sampling device which comprises a U-shaped pipe and a rotary table, water storage tanks are fixedly installed at the top end of the rotary table at equal angles, the top ends of the water storage tanks fixedly communicate with a bearing tank, and a fixing plate is fixedly installed in the middle of an inner cavity of each water storage tank; a limiting spring located in the water storage tank is fixedly installed at the top end of the fixing plate. According to the sewage discharge total amount monitoring and sampling device, the inner diameter of the receiving tank is smaller than that of the water storage tank, so that when sewage enters the receiving tank from the discharge head, a piston plate is compressed, and a limiting spring at the bottom end of the piston plate is compressed immediately; sewage can enter the water storage tank from a gap between the piston plate and the water storage tank to complete sampling, on the contrary, the piston plate can block the top end of the water storage tank, external dust and rainwater are prevented from entering the water storage tank to influence the sampling effect, and the advantage of preventing sampling from being polluted is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage monitoring, in particular to a sampling device for monitoring the total amount of sewage discharge. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. It is mainly the water after daily use, which contains more organic matter and is easier to handle. In order to ensure that the sewage is monitored to meet the discharge standard during the sewage discharge process, in the prior art, a monitoring sampling device is generally installed at the sewage discharge outlet to monitor and sample the sewage. [0003] In the discharge process of sewage, in the prior art, flow meters are generally used to monitor the flow of sewage, and sampling devices are used to sample them after monitoring, but the existing sampling devices are generally semi-open designs.

[0003] In the discharge process of sewage, in the prior art, flow meters are generally used to monitor the flow of sewage, and sampling devices are used to sample them after monitoring, but the existing sampling devices are generally semi-open designs. The monitored sewage will be directly discharged to the sampling device for sampling, but due to the semi-open design, it is easy to cause the mixing of external dust or rainwater and sewage, which will affect the accuracy of sampling and affect the detection effect
