Abstract

The invention provides a water sample pretreatment device, comprising a water inlet, a filtration component and a water outlet. And the device further includes a heating component installed between the water inlet and the filtration component for heating a water sample to a predetermined temperature, and an ultraviolet digestion component disposed between the water inlet and the filtration component for conducting ultraviolet digestion to the water sample. The device performs heating and ultraviolet digestion treatment to the water sample before filtration, so that solid phosphorous organic substances and nitrogenous organic substances can dissolve in water after decomposition and avoid being filtered out. Thus, the reliability and objectivity of monitoring and measurement of the water sample pretreatment device are improved. In addition, as part of the solid organic substances is fully dissolved, occurrence of blockage and inconvenience in cleaning are reduced. Therefore, the filtration speed is improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water sample pretreatment device. Background technique [0002] With the continuous deterioration of the global environment, environmental pollution is becoming more and more serious, especially the pollution of water bodies is very serious. Water is the source of life. At present, the quality of drinking water and the pollution of rivers, lakes, and sea water have attracted the attention of various countries. In order to implement the scientific outlook on development to achieve sustainable development, and to deal with environmental emergencies, a strict water sample monitoring system is required. Water sample pretreatment is an important part of the water sample monitoring system. [0003] At present, the water sample pretreatment device uses a filter component to filter solid substances in the water sample, and the filter component can use double-pump filtration, single-pum...
