Example Embodiment

[0034] Example 1: An insecticide pesticide production site solid waste soil ecological toxicity diagnostic method, including the following steps:

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

[0036] Combined with insecticide pesticide production site research point setting principle to treat diagnosed pesticide pesticide production site solid waste soil conduct multipoint collection;

[0037] Step 2: Preparation of solid waste soil

[0038] After the collected soil is removed, the impurities are broken, and the 5mm sieve is obtained, and the preprocessing solid waste soil is obtained;

[0039] Step 3: Ecological toxicity diagnosis

[0040] The first toxicity test, the second toxicity test and the third toxicity test were performed using the diagnostic device; wherein the first toxicity test is a toxicity test and plant germination toxicity test. The second toxicity test is a fish. Tests of type feeding toxicity, third toxicity tests for plant roots extended toxicity test...

Example Embodiment

[0052] Example 2: Different from Example 1: a method of solid waste soil ecological toxicity in pesticide production site, including the following steps:

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

[0054] Combined with insecticide pesticide production site survey point setting principle Treatment of pesticide pesticide production site solid waste soil for multi-point acquisition; separate the soil of different collection locations separately stored separately, and the soil of different collection locations Mark;

[0055] Step 2: Preparation of solid waste soil

[0056] After the collected soil batch is removed and the impurities are broken, the 5mm sieve is obtained, and the pretreatment of solid waste soil after different collection locations;

[0057] Step 3: Ecological toxicity diagnosis

[0058] The lack of solid waste soil after different collection locations is labeled in 5 groups for a batch of experiments to get A1, A2, A3, A4, A5 group; then the labeling solid...

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,...
