| Abstract: | Several composite carrier materials immobilization activated sludge ball are prepared,compared the performance of immobilized activated sludge and the wastewater COD removal rate.The results show that the wastewater COD removal rate of immobilization activated sludge is higher than the free state activated sludge,the COD removal rate of sodium alginate composite activated carbon and chitosan diatomite composite immobilized activated sludge is better.as well as the substitution degree of carboxymethyl chitosan composite diatomite immobilized activated sludge is 1.54,the wastewater COD removal rate reach maximum,48 h removal rate is 61.2%. |
