AI Technical Summary

Problems solved by technology

At present, most of the monitoring operations of water quality monitoring in my country are completed using various precision instruments, but most of the instruments have relatively high requirements on water quality. If raw water is directly used to enter the instrument, it is very likely to cause blockage or even damage the instrument. If it enters the instrument after treatment, it is very likely that the quality of the raw water has been changed, resulting in inaccurate monitoring results.

Embodiment Construction

[0020] Water quality monitoring is carried out at the environmental water quality monitoring point. When water is taken, the first drive valve 5 is closed, and the squeeze valve 8 intakes air to push the piston of the pneumatic syringe pump to move upward. The valve 9 is switched to communicate with the pneumatic injection pump 4, and the filtered sample water enters the water tank 26 in the pneumatic syringe pump 4, and then the second drive valve 6 drives the three-way switching valve 9 to switch the water tank 26 to communicate with the sample water cup 20, The extrusion valve 8 is closed, and the first drive valve 5 pushes the piston downward to inject the sample water into the sample water cup 20. The instrument in the monitoring unit automatically extracts the sample water from the sample water cup 20 through the sample water pipe 19 for analysis as required.

[0021] The inlet pipe 2 is also communicated with the front end of the water inlet pipe 1 provided with the filt...

Abstract

The invention discloses an automatic environment water quality monitoring pretreatment system which comprises a water inlet pipe 1, an air inlet pipe 2, a water outlet pipe 3, a pneumatic injection pump 4, a three-way switching valve 9, a pressure gage 14, an atomized lubricator 15, a liquid level meter 16, a filter element 17, a running water pipe 18, a sample water pipe 19, a sample water cup 20 and an overflow port 21. Raw water is pretreated before entering a monitoring instrument, and the instrument is protected and the service life of the monitoring system is prolonged on premise of not influencing the water quality monitoring result.

Description

technical field [0001] The invention relates to the technical field of environmental water quality monitoring, in particular to an automatic environmental water quality monitoring pretreatment system. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainages. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmi...
