Problems solved by technology

However, due to the simple equipment, backward technology and no relevant environmental protection measures in the production of these enterprises, their long-term production has caused serious pollution to the enterprise site.
[0003] Especially in the production sites of pesticides and pesticides, since pesticides and pesticides are not easy to evaporate, volatilize, or be decomposed by soil microorganisms, they are pollutants that remain in the soil for a long time; due to the lack of effective management and restoration, they have seriously harmed The natural environment; and it is also very easy to wash from the soil into the groundwater to pollute the groundwater, or migrate with the surface runoff to pollute the surface water

Embodiment 1

[0034] Embodiment 1: A method for diagnosing the ecotoxicity of solid waste soil at an insecticide and pesticide production site, comprising the following steps:

[0035] Step 1: Collection of site solid waste soil

[0036] Multi-point collection of solid waste soil in pesticide and pesticide production sites to be diagnosed is carried out in combination with the layout principles of pesticide and pesticide production sites;

[0037] Step 2: Pretreatment of Solid Waste Soil

[0038] After removing impurities, the collected soil is crushed and passed through a 5mm sieve to obtain pretreated solid waste soil;

[0039] Step 3: Ecotoxicity Diagnosis

[0040] The first toxicity test, the second toxicity test, and the third toxicity test are simultaneously carried out on the pretreated solid waste soil by using a diagnostic device; among them, the first toxicity test is an earthworm toxicity test and a plant germination toxicity test, and the second toxicity test is a fish toxicit...

Embodiment 2

[0052] Embodiment 2: The difference from Example 1 is: a method for diagnosing the ecotoxicity of solid waste soil in an insecticide pesticide production site, comprising the following steps:

[0053] Step 1: Collection of site solid waste soil

[0054] Combining with the layout principle of pesticide production site survey points, the solid waste soil of pesticide production site to be diagnosed is collected at multiple points; the soil at different collection sites is stored separately at 5°C, and the soil at different collection sites to mark;

[0055] Step 2: Pretreatment of Solid Waste Soil

[0056] Remove impurities in batches from the collected soil, then crush it, pass through a 5mm sieve, and obtain pretreated solid waste soil from different collection locations;

[0057] Step 3: Ecotoxicity Diagnosis

[0058] The pretreated solid waste soils from different collection sites were labeled with 5 groups as a batch of experiments to obtain groups A1, A2, A3, A4, and A5...

Embodiment 3

[0063] Embodiment 3: The difference from Example 1 is: a method for diagnosing the ecotoxicity of solid waste soil in an insecticide pesticide production site, comprising the following steps:

[0064] Step 1: Collection of site solid waste soil

[0065] Combining with the layout principle of pesticide production site survey points, the solid waste soil of pesticide production site to be diagnosed is collected at multiple points; the soil at different collection sites is stored separately at 5°C, and the soil at different collection sites to mark;

[0066] Step 2: Pretreatment of Solid Waste Soil

[0067] Remove impurities in batches from the collected soil, then crush it, pass through a 5mm sieve, and obtain pretreated solid waste soil from different collection locations;

[0068] Step 3: Ecotoxicity Diagnosis

[0069] The pretreated solid waste soils from different collection sites were labeled with 5 groups as a batch of experiments to obtain groups A1, A2, A3, A4, and A5...

Abstract

The invention discloses a method and device for diagnosing ecotoxicity of solid waste soil in a pesticide production site. The method specifically comprises the steps of collection, pretreatment and diagnosis. The device comprises first test equipment, second test equipment and third test equipment which are connected in sequence. According to the method provided by the invention, a pesticide production site containing solid waste soil to be diagnosed is collected in a multi-point collection mode; and a plurality of diagnosis modes are used for diagnosis, so that the method has better accuracy and high efficiency. The device provided by the invention is reasonable in overall structural design, the first test equipment, the second test equipment and the third test equipment are matched for use, so that various different diagnosis modes can be carried out on the soil to be diagnosed, and more and more detailed experiments can be carried out within effective experiment time to improve the soil ecotoxicity diagnosis efficiency.

Description

technical field [0001] The invention relates to the technical field of soil ecological environment, in particular to a method and device for diagnosing the ecotoxicity of solid waste soil in an insecticide and pesticide production site. Background technique [0002] Pesticides can prevent and control diseases, insects, and weeds. If used properly, they can increase crop yields, but they are a very harmful type of soil pollutants. With the development of our industrialization process, more and more small and medium-sized chemical companies have shut down or relocated after receiving environmental protection requirements. However, due to the simple equipment, backward technology and no relevant environmental protection measures in the production of these enterprises, their long-term production has caused serious pollution to the enterprise site. [0003] Especially in the production sites of pesticides and pesticides, since pesticides and pesticides are not easy to evaporate,...
