The invention discloses a sampling device for worms in drinking water and a use method of the sampling device. An electromagnetic signal control system and an ultrasonic vibration principle are taken as the core, an integrated intelligent electromagnetic flowmeter induction device is used for inducting the change of the drain water flow, the blockage system of a worm intercepting system is grasped timely and accurately, an electrical signal is sent to an electromagnetic signal control system accordingly, the electromagnetic signal control system sends an instruction to close an electric regulating valve, water feeding is cut off, and an ultrasonic vibrator is started to be used for switching on and switching off the sampling device automatically. The sampling device can achieve the objective of worm collection by the aid of a 45-degree T-pipe and a worm collecting tank at the bottom on the basis of a free settling principle, fills in the blank in the field of automatic sampling of worms in drinking water, and has the advantages of being high in efficiency, intelligent, automatic, convenient to use, quick to detect, wide in application range and the like.
Description
technical field [0001] The invention relates to a worm sampling device, in particular to a worm sampling device in drinking water. The invention also relates to a method for using the drinking water worm sampling device. Background technique [0002] Common worm-like aquatic organisms ("worms" for short) in water sources include copepods, oligochaetes, nematodes and chironomus larvae. In recent years, as the problem of eutrophication has intensified, the algae in the source water have proliferated and the content of organic matter has increased, resulting in a continuous increase in the density of worms, which often easily enter the water plant with the raw water. Once the worms enter the water plant, due to their strong penetrating ability, they can easily penetrate the water purification units and finally enter the urban water supply network. The worm itself is not harmful, but on the one hand, it is easy to cause water quality panic because of its bright color and is vi...
