Bottle bottom inflow type water sample collecting device and method

Abstract

The invention belongs to the technical field of water sample collection, and particularly discloses a bottle bottom inflow type water sample collecting device and a method. According to the bottle bottom inflow type water sample collecting device, a collecting device is directly inserted into a water body from the bottom to ensure that a water sample enters the collecting device from the bottom ofthe collecting device, so that the collection of the water sample is completed in a natural state without forming strong disturbance and mixing, and a layering effect of a water system in the naturalstate can be effectively maintained, thereby facilitating stereoscopic analysis of comprehensive characteristics of the water system. The collecting device provided by the invention can be used as auniversal water sample collecting device to collect water samples.

Description

technical field [0001] The invention belongs to the technical field of water sample collection, and more particularly relates to a bottle bottom inflow type water sample collection device and method. Background technique [0002] Water quality is an important evaluation index to measure the quality of the ecological environment, a key factor to ensure the integrity of the ecological system, and is directly related to people's drinking water safety and physical health. Water quality monitoring and analysis is to monitor and determine the types of pollutants in the water body, the concentration of pollutants and the trend of change, as well as to analyze the types of microorganisms and mineral elements in the water system, including unpolluted and polluted natural water, such as rivers, rivers, lakes , sea and groundwater and various industrial drainage, etc., evaluate and analyze the temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, ch...

Problems solved by technology

Selecting a suitable water sample collector is very important to ensure the stability of the water sample. The traditional water sample collection device generally enters the water from the mouth of the bottle. When collecting water samples, it can only collect water samples from a certain area near the mouth of the bottle. When it is necessary to analyze the stratification characteristics of the water system, it is necessary to collect water samples at different depths, and it is easy to form strong disturbances and mix when entering the collection bottle, which cannot effectively maintain the stratification effect in the natural state of the water system, and it is difficult to analyze the water system three-dimensionally comprehensive characteristics
