Water sampling and sample mixing system for outdoor water quality automatic monitoring station and method thereof

Abstract

The invention provides a water sampling and sample mixing system for an outdoor water quality automatic monitoring station. The system comprises: a sample mixing cup, a water acquisition pipeline anda timer, wherein the sample mixing cup is provided with a water inlet, an overflow port and a water outlet; the water acquisition pipeline comprises a front pipeline, a sampling pipe, an overflow pipe, a breather pipe and an exhaust pipe; and the timer is connected to a water inlet valve, a recoil valve, a sampling valve and a blowoff valve, and is used for controlling the opening cycle and opening times of the water inlet valve, the recoil valve, the sampling valve and the blowoff valve. Through the technical scheme of the invention, each monitoring object is a mixed water sample in two watersampling monitoring interval times, which can reflect the comprehensive situation of water quality in the monitoring blank time period to some extent.

Description

technical field [0001] The invention relates to the technical field of environmental protection water quality monitoring, in particular to a water sampling and mixing system for an outdoor water quality automatic testing station and a water sampling and mixing method for an outdoor water quality automatic testing station. Background technique [0002] With the development of science and technology, more and more attention has been paid to environmental protection. As a subdivision of environmental protection, the water quality monitoring industry has also attracted more and more attention from the public. There is no sample mixing process in the sampling system of conventional automatic water quality monitoring stations. General The standard sampling monitoring cycle is once every 4 hours, and the monitoring interval is long. During the two monitoring intervals of water collection, if there is sneak discharge or leakage of the measured water body, it cannot be captured, makin...

[0002] With the development of science and technology, more and more attention has been paid to environmental protection. As a subdivision of environmental protection, the water quality monitoring industry has also attracted more and more attention from the public. There is no sample mixing process in the sampling system of conventional automatic water quality monitoring stations. General The standard sampling monitoring cycle is once every 4 hours, and the monitoring interval is long. During the two monitoring intervals of water collection, if there is sneak discharge or leakage of the measured water body, it cannot be captured, making the monitored data unrepresentative and unable to monitor the actual water quality. nature
