The Main reasons of Groundwater Quality On-line Monitoring
Date:2024-11-12 Browse: 5

With the continuous improvement of people’s living standards, the society continues to progress. Wastewater discharge is constantly increasing! Through some online information, Xiaobian learned that the growth of wastewater discharge increased from 43.3 billion tons in 2001 to 68.5 billion tons in 2012, an increase of 25.2 billion tons in 12 years, an average annual discharge of 2.1 billion tons of wastewater, the average annual compound growth rate of about 4.3%.

 

From the perspective of wastewater pollution sources, China’s wastewater pollution sources are mainly divided into industrial sources, agricultural sources, urban living sources, and a small number of centralized pollution facilities discharge sources, of which the increase in urban living source sewage discharge is the main reason for the increase in wastewater discharge in China. Therefore, the small edition of Gansu water quality testing will give you a talk about the detection method of groundwater today. The construction unit shall establish and improve the water environment monitoring system, and monitor the groundwater in the factory area and the surrounding area. The layout of monitoring points should follow the following principles:

Focus on the construction of the factory area and take into account the periphery: monitoring points should be set up near possible polluting facilities in the factory area, such as toxic raw material storage tanks, sewage storage pools, and solid waste stacking sites.

 

Focus on Downstream Monitoring, Both Upstream and Lateral.

Stratified monitoring of groundwater, with emphasis on shallow, vulnerable diving and aquifers as sources of drinking water, taking into account other aquifers.

Groundwater monitoring should be carried out at least twice a year, divided into high and low water periods, and the frequency of monitoring should be increased in key areas and under abnormal circumstances.

Water quality monitoring projects can refer to the “drinking Water Quality standards” and “groundwater quality standards”, and monitoring projects can be appropriately increased and reduced in light of regional conditions. The monitoring project must include the characteristic pollution factors of the construction project, for example, the monitoring project of the refinery must include petroleum hydrocarbons, benzene, xylene and other characteristic pollutants.
