Description

Technical Field

[0001] The present invention belongs to the technical field of water quality monitoring and relates to an intelligent online pretreatment system and method for high-turbidity water. Background Art

[0002] Online monitoring of high-turbidity water (turbidity >100 NTU, or even above 1000 NTU) presents significant challenges in power plant desulfurization systems, environmental monitoring, industrial wastewater treatment, and municipal water services. Sediment, algae, and organic particulates can easily clog sampling lines or cover optical sensor windows, distorting data and severely impacting instrument accuracy and service life. Currently, filtration is often used to pre-treat water samples, but this method is highly susceptible to membrane contamination, requiring frequent backwashing or replacement, resulting in high labor and replacement costs. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an intelligent online pretreatment system and method for high turbidity water, which can improve the measurement accuracy and service life of the instrument while being low in cost.

[0004] To achieve the above object, the present invention discloses an intelligent online pretreatment system for high turbidity water, comprising a sample input pipeline, a sample circulation pool, a sample sedimentation pool, a sample clear water pool and a water sample analysis instrument;

[0005] The sample input pipe is connected to the bottom inlet of the sample circulation pool. A sample injection valve is provided on the sample input pipe. The outlet on the upper side of the sample circulation pool is connected to the inlet of the sample sedimentation pool via the sample sedimentation pool inlet valve. The top outlet of the sample sedimentation pool is connected to the inlet of the sample clear water pool via the sample clear water pool inlet valve. The outlet at the top of the sample clear water pool is connected to the water sample analysis instrument via the water sample analysis instrument sampling pump.

[0006] Furthermore, a bottom sewage valve of the sample sedimentation tank is provided at the bottom sewage outlet of the sample sedimentation tank.

[0014] The present invention discloses an intelligent online pretreatment method for high turbidity water, comprising the following steps:

[0015] The sample injection valve is controlled to be opened, and the sample sedimentation tank inlet valve is controlled to be closed. The sample enters the sample circulation tank through the sample injection valve. When water sample analysis is required, the sample sedimentation tank inlet valve is controlled to be opened, and part of the sample enters the sample sedimentation tank through the sample sedimentation tank inlet valve. Then the sample sedimentation tank inlet valve is controlled to be closed, and the sample is subjected to sedimentation treatment in the sample sedimentation tank.
