Abstract

The invention relates to a sampling device, in particular to a sampling device for wastewater quality detection. The sampling device for wastewater quality detection is provided, wherein the samplingdevice is uniform in sampling and can indirectly sample. The sampling device for wastewater quality detection comprises a box, a handle, a square box, a hydraulic water suction mechanism, and a movingmechanism, wherein a fixing block is arranged on one side of the box; the handle is arranged on the other side of the fixing block; the square box is arranged at the other end of the handle; the hydraulic water suction mechanism is arranged on the fixing block; and the moving mechanism is arranged inside the box. Firstly, a worker needs to enable a first test tube opening to be located below a water nozzle, and the worker starts a servo motor to rotate forwards, so that wastewater on the upper layer flows into a cylinder body, and then the worker enables the servo motor to rotate reversely, so that the wastewater on the upper layer flows into a first test tube; and then flow guide cylinders are inserted into the wastewater at the middle layer and the lower layer correspondingly, and the wastewater at the middle layer and the lower layer can be sampled by repeating the first action.

Description

technical field [0001] The invention relates to a sampling device, in particular to a sampling device for testing sewage water quality. Background technique [0002] Water quality testing is the quality testing of water bodies. However, water bodies include not only water, but also suspended solids, substrates and aquatic organisms coexisting in water. Therefore, water quality testing and evaluation should include water phase, solid phase and biological phase, in order to get a comprehensive , correct conclusion. [0003] Sewage water quality testing is an important basis for evaluating the sewage treatment effect of sewage treatment plants. Before sewage testing, it is necessary to take samples of sewage, but the current sampling is manual direct sampling. This method often results in uneven sampling samples. There is also the problem of polluting people's hands during the process. [0004] Therefore, it is especially necessary to invent a sampling device for sewage water...
