Problems solved by technology

[0010] Although the above-mentioned phytoremediation technology has many advantages, there are still many imperfections, and there are certain limitations in practical application. and external constraints
[0011] The above-mentioned remediation methods for soil polluted by organophosphorus pesticides may not completely eliminate the organophosphorus pesticide pollutants in the soil, or bring new pollutants, or their use is restricted by environmental conditions, so there are various defects Therefore, it is necessary to explore a kind of soil remediation agent that has a good effect of removing organophosphorus pesticides and is milder and does not produce new pollution in view of the above-mentioned status quo.

Embodiment 1

[0084] Take the soil sample polluted by organochlorine pesticides, and then take the soil remediation agent according to the ratio of 50 grams of soil remediation agent per 1000 grams of soil sample;

[0085] Add the following raw materials to the soil sample: chitosan, bentonite, green algae, citric acid, shell powder, enoki mushroom chaff, corn cob, rice bran, tea seed shell, walnut shell, betel nut wood chips, palm wood chips;

[0086] The parts by weight of each raw material are as follows:

[0087]

[0088] Mix with soil samples and keep for 48 hours;

[0089] The bacterium powder that the present invention adopts, enzyme are all derived from commercially available;

[0090] Chlorella is dried and pulverized algal powder with a water content of about 3%;

[0091] Corn cobs are dried and crushed granules with a water content of about 4%;

[0092] Walnut shells are also dried and pulverized powders with a water content of about 3%;

[0093] Betel nut wood chips and p...

Embodiment 2

[0126] Exactly the same as the soil sample in Example 1, adopt the same method as Example 1 to remove the organophosphorus pesticide in the soil sample, the difference is that the parts by weight of the soil remediation agent etc. are different;

Abstract

The invention belongs to the technical field of oil remediation, and particularly relates to an organophosphorus pesticide contaminated soil remediation agent. The organophosphorus pesticide contaminated soil remediation agent is prepared from chitosan, bentonite, green algae, citric acid, shell powder, needle mushroom residues, corn cobs, rice bran, tea seed shells, walnut shells, areca sawdust, palm sawdust, a composite enzyme preparation and a compound microbial agent. According to the soil remediation agent, under the condition that no other chemical solvent is introduced, the mild enzyme and the microbial agent are adopted to soil treatment, secondary pollution is not produced, and action conditions are mild.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to an organophosphorus pesticide-contaminated soil remediation agent. Background technique [0002] Because organophosphorus pesticides are not easy to oxidize, decompose, and be degraded by microorganisms, they can stay in the environment for a long time and may undergo chemical changes to become more toxic and harmful secondary pollutants. At the same time, the components remaining in plants can be enriched through the food chain, so that the amount of pesticide residues in food exceeds the hygienic standard. Organophosphorus pesticides can enter the human body through the digestive tract, respiratory tract and intact skin and mucous membranes. Occupational pesticide poisoning is mainly caused by skin pollution. Absorbed organophosphorus pesticides are distributed in various organs in the body, among which the liver has the largest content, and the content i...
