Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling technology, specifically a wastewater sampler for environmental monitoring. Background Technology

[0002] Environmental monitoring, also known as environmental surveillance, refers to the activities of environmental monitoring agencies in monitoring and measuring the environmental quality. This involves using modern technologies such as chemistry, physics, biology, medicine, telemetry, remote sensing, and computers to monitor and measure indicators reflecting environmental quality in order to determine the level of environmental pollution and environmental quality. Wastewater sampling in environmental monitoring is a crucial step in ensuring the accuracy and representativeness of water quality data. Drinking water sources should be sampled no less than 12 times a year, with the sampling time determined according to specific circumstances. For water bodies such as rivers, lakes, and reservoirs, different sampling frequencies are set according to the degree of pollution and monitoring needs, such as monthly, quarterly, or annually. For well points with abnormal conditions or heavily polluted areas, the sampling and monitoring frequency should be appropriately increased. By collecting water samples at specific times or under specific conditions, data on the highest, lowest, or changing values ​​of pollutants can be obtained. However, existing wastewater samplers have short suction tubes, making it difficult for them to sample wastewater in deeper water areas and meet the needs of wastewater sampling at greater depths. Utility Model Content

[0003] The purpose of this utility model is to provide a wastewater sampler for environmental monitoring, so as to solve the problems mentioned in the background art, such as the short suction pipe of existing wastewater samplers, the difficulty of samplers to perform wastewater sampling in deeper water areas, and the inability to meet the requirements of wastewater sampling at different depths.
