Sampling device for sampling and detecting of sewage treatment

Abstract

The invention, which relates to the field of sewage treatment, discloses a sampling device for sampling and detecting of sewage treatment. The device comprises a lower casing and an upper casing thatare in threaded connection to form a sealed cavity sphere. A balancing weight is installed at the bottom of the inner side of the lower casing; a water pump is mounted on the middle portion of the topsurface of the balancing weight; a first sealing sleeve is embedded in the bottom of the balancing weight; and bottom of the first sealing sleeve penetrates the bottom of the lower casing and is flush with the bottom surface of the lower casing. Besides, a sampling tube is installed at the bottom of the lower casing. The water pump draws waste water; and with guidance by a pile-up valve, samplingand the movement of the device can be realized, so that the flexibility is greatly enhanced and the automation operation is performed. The sampling point and the sampling depth can be adjusted; and the collected sample data become comprehensive. The connecting sleeve inside the upper casing is in threaded connection with a sampling bottle firmly and reliably; and the bottle body is arranged inside the casing, so that the safety is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sampling device for sampling and detection of sewage treatment. Background technique [0002] At present, in environmental monitoring and water quality treatment, pumps are generally used as the sampling power to sample water quality at different depths. The sampling equipment is complex and heavy, and it is even more inconvenient far away from the power supply. In the sewage treatment plant, the sludge return pump should be controlled by measuring the mud-water interface height and sludge concentration in the sedimentation tank, so as to obtain a suitable amount of return sludge. Since there is a mud scraper in the sedimentation tank that regularly rotates in a circular motion, it is not suitable to install a fixed mechanical mud-water interface measuring device in the sedimentation tank. [0003] According to the product provided by the patent document CN201821043279.1, it is...

Problems solved by technology

However, the water body collection cup and the sewage sampling device are not integrated, and there are many restrictions in the process of collecting sewage samples. For example, the sampling device can only be located near the water body collection cup. Once the sewage liquid level is lower than the sampling point, then A long water delivery hose is required; in places where the bottom surface is uneven, in order to ensure the safety of the water body collection cup, one hand must hold the cup and the other hand holds the sampling device, which is inconvenient to operate and has no effect on the safety of the water body collection cup. Guarantee; Most of the sewage samples obtained are located near the sampling point, and the sampling data is single
