Abstract

The invention discloses a composite ecological repairing agent as well as a preparation method and the application thereof. The repairing agent is prepared from the following raw materials in parts by weight: 23 to 31 parts of a shell powder, 1 to 5 parts of vinyl trimethoxysilane, 3 to 7 parts of acetylpropionic acid, 15 to 25 parts of a konjaku powder, 5 to 12 parts of sodium butyrate and 11 to 19 parts of wood vinegar. The preparation method comprises the following steps: smashing shells, adding an acetylpropionic acid solution, and heating to prepare a shell powder treatment substance; smashing konjaku, mixing the konjaku powder with a vinyl trimethoxysilane solution, and performing heating and stirring treatment, so as to prepare a mixture A; mixing the wood vinegar with a citric acid aqueous solution, and performing heating and stirring, so as to prepare a mixture B; mixing the shell powder treatment substance, the mixture A, the mixture B and sodium butyrate, and performing heating and stirring, so as to obtain the composite ecological repairing agent. The composite ecological repairing agent can transfer, convert and degrade pollutants in water, promote water stabilization and enhance the impact resistance to gradually recover the self-cleaning functions of an aquatic ecosystem and water, and can shorten the fish harvesting time. The composite ecological repairing agent can obviously degrade the content of cypermethrin in soil and effectively improve the quality of the soil.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a composite ecological restoration agent and its preparation method and application. Background technique [0002] With the development of society, environmental problems are becoming more and more serious. Water pollution and residues of highly toxic pesticides have received more and more attention. Among them, the pollution of my country's urban landscape water, ecological lakes, river water environment, rural domestic sewage, and aquaculture circulating water has been further intensified. At present, my country often uses water treatment devices for the treatment of these water environments. These devices not only consume electricity, but also can only be effective during treatment. Once they are stopped, the water environment will continue to deteriorate. Among the highly toxic pesticides, cypermethrin is a large class of pesticides that are artificially synt...
