Benefits of technology

This patented technology helps remove organophosphorus compounds (OPC) that are harmful substances found on crops such as citrus fruits or vegetables while also reducing their impact on healthy plants like tomatoes. By doing this it saves money over time compared with traditional methods where only one type of chemical needs be removed separately.

Problems solved by technology

This patented describes methods for treating and repairing unsaturated halochemistry (unsaturation) pesticids from their carboxylate structures called cis-1, trans-2, 2'-trichioro-4', 4'-hexadecyl esters. However, these chemicals may remain active over longer periods of storage in sediment containing various other materials like calcium carbonates and silica gel. Existing techniques involve decompositing these ingredients before disposal, leading to potential negative effects upon humans and animals who consume those products.

Abstract

The invention provides a method for remediating soil co-contaminated by organochlorine pesticides and cadmium. The remediation method comprises the following steps: step 1, crushing the soil to be repaired, adding water, and turning the soil; step 2, adding additives, the Additives include distiller's grains, potassium palmitate, molecular sieves, humic acid, fly ash, silicon oxide, attapulgite, borax and sugarcane ash, turn over the soil, and let stand; Step 3, spray the seed liquid, the seed liquid includes Sporophages, Trichoderma, Lactococcus, covered with film; step 4, add compound fertilizer, turn over the soil, plant alfalfa and mountain lettuce seedlings, and harvest. The restoration method provided by the invention can simultaneously restore soil polluted by organochlorine pesticides and heavy metal cadmium, can shorten the restoration period, improve restoration and treatment efficiency, and has a significant and thorough restoration and treatment effect on soil polluted by organochlorine pesticides and heavy metal cadmium, and has broad application potential. Application prospects.
