Study on acephate wastewater treatment with immobilized microorganism

摘要

Alginate-diatomite immobilized microspheres were prepared through immobilized biosorption of diatomite and Aspergillus niger by sodium alginate. Three major factors such as alginate concentration, diatomite content and embedding capacity on physical properties and microbial activity of Alginate-diatomite immobilized microspheres were investigated, and the optimal preparation conditions of Alginate-diatomite immobilized microspheres were determined as 2% of alginate, 1% of diatomite, 10% of Embedding capacity.
