Abstract

The invention discloses a reaction device for simulating migration and transformation of a soil organic pollutant, relates to a reaction device, and solves the problem that existing leaching experiment equipment for simulating the migration and transformation of the soil organic pollutant is large in experimental error, low in equipment use ratio and poor in adaptability The reaction device comprises a first water box, a second water box, a water pump, a water inlet pipe, a steady flow pipe, a support, a supporting frame, a base, a fixed plate, a first regulating valve, a second regulating valve, multiple flowmeters, multiple sieve hole plates, multiple earth pillars and multiple fifth regulating valves, wherein the first water box, the support and the supporting frame are all arranged on the base; the fixed plate is connected with the supporting frame, and the second water box is supported through the supporting frame; the supporting frame is provided with the multiple earth pillars which are vertically arranged, each flowmeter is arranged right above each earth pillar, the multiple flowmeters are fixedly arranged on the fixed plate, and the sieve hole plates are fixedly arranged on the support. The reaction device disclosed by the invention is used for simulating the migration and transformation of the soil organic pollutant.

Description

technical field [0001] The invention relates to a reaction device, in particular to a reaction device for simulating the migration and transformation of organic pollutants in the soil environment. Background technique [0002] In the research of ecology and environmental science, in order to accurately grasp the chemical behavior of organic pollutants in the soil environment, it is usually necessary to carry out soil column leaching simulation experiments. The existing equipment used for leaching experiments is mostly simple plexiglass. Or PVC soil columns, etc., but these simple soil columns have the following disadvantages: non-integrated processing devices, too much human assistance, resulting in test errors; unable to conduct multiple tests at the same time, poor parallelism, resulting in test errors; unable to accurately control leaching The speed and amount of leaching lead to experimental errors; due to the limitation of materials, some organic pollutants cannot be st...
