Embodiment 1

[0036] Embodiment 1: the influence of sodium alginate dosage on immobilization effect

[0037] Prepare the immobilization matrix of sodium alginate and biochar, the ratio of sodium alginate to immobilization matrix (m:V) is 0.5, 1.0, 2.0, 3.0 and 5.0 g:100.0 mL, the ratio of biochar to immobilization matrix (m:V) is 0.2 g:100.0 mL. Add the wet Aspergillus niger cultured for 30 h to the immobilization matrix, so that the ratio (m:V) of the wet Aspergillus niger to the immobilization matrix is ​​6.0 g:100.0 mL, mix the above solution evenly, and perform the immobilization operation , at a height of about 10 cm from the liquid surface, use a ball maker with a diameter of 4 mm to drop the mixed solution into 20.0 g / L calcium chloride solution drop by drop, immobilize for 2 hours, filter out the balls, and use Wash 2-3 times with sterile water, collect and set aside.

[0038] The immobilized Aspergillus niger was added to the deltamethrin wastewater with a concentration of 50.0 m...

Embodiment 2

[0039] Embodiment 2: the influence of calcium chloride concentration on immobilization effect

[0040]Using the determined optimal conditions and under the condition that other conditions remain unchanged, drop the mixed solution into calcium chloride solutions with mass concentrations of 5.0, 10.0, 20.0, 30.0 and 50.0 g / L respectively. After 2 hours, the pellets were filtered out, washed 2-3 times with sterile water, collected and set aside.

[0041] The experimental methods and evaluation indicators are the same as above.

Embodiment 3

[0042] Embodiment 3: The influence of biochar dosage on immobilization effect

[0043] Using the determined optimal conditions and keeping other conditions unchanged, the effect of the amount of biochar on the performance of immobilized Aspergillus niger was studied, and the ratio (m:V) of biochar to immobilized substrate was set to 0.01 and 0.05 respectively , 0.10, 0.20 and 0.50 g: 100.0 mL, the preparation method is the same as above.

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...
