Sewage filtering device for environmental engineering water quality detection

Abstract

The invention relates to the technical field of environmental engineering, and discloses a sewage filtering device for environmental engineering water quality detection. The device comprises a filtering pipe, a filtering plate is movably connected in the filtering pipe, a filtering plate shaft is fixedly connected in the middle of the filtering plate, and the filtering plate divides the filtering pipe into an upper part and a lower part. A non-dissolved pollutant area and an insoluble pollutant area are arranged on the upper side of the filtering pipe, a soluble pollutant area is arranged on the lower side of the non-dissolved pollutant area and the insoluble pollutant area, a debonding area side wall is fixedly connected to the position, at the same height as the filtering plate, of the bottom side of the filtering pipe, and limiting stop blocks are fixedly connected to the two ends of the debonding area side wall. According to the sewage treatment device disclosed by the invention, sewage is filtered through the filtering plate, soluble and insoluble pollutants in the sampled sewage are separated, and the separated sewage can be correspondingly treated and detected subsequently, so that more accurate detection data can be obtained.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a sewage filter device for environmental engineering water quality detection. Background technique [0002] Since the development of agriculture, in order to increase the output of agricultural products and the quality of agricultural products, human beings have applied a large amount of chemical fertilizers, fungicides, herbicides and other chemical agents. The pollution of agricultural sewage has become increasingly serious, and the ecological balance has been affected or even destroyed. Farmland runoff has been sprayed with pesticides. And the application of chemical fertilizers, generally only a small amount is attached or applied to crops, and most of the rest remain in the soil and float in the atmosphere, and then enter the surface water through rainfall and runoff, causing water pollution, while the drinking water of Chinese residents comes from surface w...
