Sample treatment device for testing sewage pollutants

Abstract

The invention discloses a sample treatment device for testing sewage pollutants. The sample treatment device comprises a base, wherein supports are respectively and fixedly connected to two sides of the top of the base; a fixed plate is fixedly connected to the inner side upper ends of the outer walls of the supports; a first box body is fixedly connected to the bottom of the fixed plate; a firstmotor is fixedly connected to the bottom of the inner wall of the first box body through a motor base; a rotating shaft is rotationally connected to one side of the first motor through an output shaft; a first bevel gear is fixedly connected to one end, away from the first motor, of the rotating shaft; a mounting shaft is rotationally connected to the top of the inner wall of the first box body; asecond bevel gear is fixedly connected to the upper end of the outer wall of the mounting shaft and is meshed with the first bevel gear; one end, away from the first box body, of the mounting shaft,penetrates through the first box body and extends to the outer part of the first box body. The invention relates to the technical field of soil detection; the problems that manual grinding is needed before detection of a detected sample so as to waste labor force, and low grinding efficiency and poor grinding effect are produced are solved.

Description

technical field [0001] The invention relates to the technical field of sewage pollutants, in particular to a sample processing device for testing sewage pollutants. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Sewage will pollute a lot of polluted land. Soil safety testing is to detect harmful substances in soil, stones, etc. according to national indicators, mainly for the detection of some harmful and toxic indicators, such as heavy metals, aflatoxin, etc., among which microbial detection is commonly used It is a kind of soil detection method. Before the microbial detection of the soil, the sample needs to be processed in advance to make it into a form that is convenient for detection. The com...
