Description

Pretreatment equipment for water quality detection Technical Field The utility model relates to the technical field of water quality detection, in particular to pretreatment equipment for water quality detection. Background The water quality detection is to monitor and evaluate various pollutants in the water body, understand the water quality condition and protect the health of water resources. The water needs to be pretreated before the water quality detection of part of the water with more impurities, and larger impurities in the water are removed, so that the water needs to be filtered. The utility model of 202323184165.2 discloses a water quality detection pretreatment device, which is similar to the water quality detection pretreatment device of the above application, and has the following defects that in the pretreatment process, a simple filter screen is generally adopted for filtering, the filtering efficiency is low, and the impurity removal is troublesome. Accordingly, in view of the above, research and improvement have been made on the conventional structure and the conventional defects, and a pretreatment apparatus for water quality detection has been proposed. Disclosure of utility model The utility model aims to provide pretreatment equipment for water quality detection, so as to solve the problems in the background technology.
