Abstract

The invention relates to a preparation method of an environment-friendly organic waste water biological purifier, which relates to a preparation method of the waste water purifier. The immobilized Aspergillus niger of the present invention is prepared by immobilizing Aspergillus niger with sodium alginate combined with biochar. The preparation method includes (1) preparing biochar; (2) adding sodium alginate and prepared biochar into water and mixing uniformly to prepare an immobilization matrix; (3) mixing domesticated Aspergillus niger and the immobilization matrix evenly, Add dropwise into the calcium chloride solution for reaction to obtain the immobilized Aspergillus niger purifying agent. The immobilized Aspergillus niger purification agent of the present invention not only has rapid adsorption capacity for deltamethrin, but also has the advantages of high efficient degradation capacity and high reutilization rate. The purification agent has simple process method, good product quality stability, low cost, good application effect, and good economic and environmental benefits.

Description

technical field

[0001] The invention relates to a preparation method of a waste water purifying agent, in particular to a preparation method of an environment-friendly organic waste water biological purifying agent. Background technique

[0002] my country is a large agricultural country, and pesticides have always been the pillar industry of my country's agricultural economy, making outstanding contributions to the development of the national economy. Pyrethroid pesticides have become the main varieties produced in large quantities and widely used at home and abroad because of their economical, efficient, and convenient features in the control of agricultural pests. As a synthetic third-generation pyrethroid insecticide, deltamethrin has the characteristics of high activity, low dosage and light stability, and has become the main species for preventing and controlling insect pests in agriculture, animal husbandry, fishery and forestry. However, with the rapid development o...
