Description
Technical field
The present invention relates to water quality monitoring field, concrete, the present invention relates to a kind of water quality monitoring system, more specifically, the present invention relates to a kind of continuous on-line monitoring system of water quality。
Background technology
The water quality monitoring of natural environment field is in great demand, from river, reservoir, pond, bay be required for water environment is carried out periodic monitoring to water factory, sewage treatment plant etc., particularly the ground such as the offshore sea waters of occurrence of large-area red tide, the lake that wawter bloom occurs and reservoir needs water quality quick and precisely to be monitored and controls。Take back test in laboratory analysis not only length consuming time with manual sampling, and lack the continuous monitoring to change of water quality, it is impossible to meet the demand that waters is emergent and manages。Develop a kind of movably continuous, on-line measurement device to be highly desirable to。
Water quality measurement commonly use some chemistry quick, biological quick, ion is quick, photoelectric technology class sensor obtains the relevant parameter values of water sample in sampling pond, bubble and turbulent flow in water sample can affect measurement effect。Especially, when water quality measurement is real-time online or when continuously carrying out, the water sample in sampling pond is it is essential to ensure that change in real time, and the water sample of replacing must assure that the turbulent flow do not brought and the accuracy of aeration measurement effect and measurement because of fluid system。Excessive sampling pond can affect water sample renewal speed, will not be inconsistent with geographical coordinate, the water sample in sampling pond, if the water particularly on probe measurement face can not be changed in time simultaneously, can affect positional information and the precision of measurement。
Dewatering outside the mating of case and flow velocity, the turbulent flow entering the water sample of analysis system can affect the uniformity of sample, and bubble can affect the accuracy of sensor measurement。Therefore, also needing in water quality online analyzer include degassing bulb apparatus and current equalizer, the probe water sample meeting geo-stationary otherwise installed in some remote corners, the data only obtained by diffusion are inaccurate。Or probe is directly goed deep in water body, does not ensure that probe detection surface never exposes in atmosphere once mobile, or being not fee from searching surface sticks steam bubble。The hydrospace detection moved around also is easily damaged sensor probe。
Summary of the invention
Present invention seek to address that at least one in prior art Problems existing or provide at a kind of useful business selection, for this, the present invention provides a kind of water quality monitoring system。
According to an aspect of of the present present invention, the present invention provides a kind of water quality monitoring system, this system includes: bubble removal device, sensor and sampling pond, described bubble removal device is in order to remove the bubble in water sample to be measured, there is the water entering section being sequentially connected with, body and outlet part, described water entering section is in order to input water sample, described body is in order to remove the bubble in described water sample, described outlet part is in order to export described water sample to described sampling pond, described sensor is placed in described sampling pond, in order to monitor described water sample, described sampling pond is provided with discharge outlet, in order to discharge described water sample。
This water quality monitoring system on the one hand of the present invention, its sampling pond is current-sharing sampling pond, water entirety in sampling pond can form the state of a Uniform Flow, ensure that probe (sensor) measuring surface has the detected water sample of new exchange, it also is able to ensure when Multi probe is measured, the water body of the measuring surface of multiple probes obtains equal replacing in time, it is possible to water body is accurately measured。This system of the present invention is capable of the demand of mobile continuous print accurate measurements water sample。
