Study on Treatment Effect of Three Types of Industrial Wastewater by Ammonium Molybdate-Modified Bentonite

Abstract:

Ammonium molybdate modified bentonite was prepared from bentonite using ammonium molybdate as modified agent, which was used to remove several industrial effluents. It is used in the pretreatment of monosodium glutamate wastewater, slaughtering wastewater and beer wastewater which have high concentration of COD. The suitable reaction condition is ensured and the treatment effects for the treated effluents are compared by ammonium Molybdate-modified Bentonite. The result shows that the ammonium molybdate-modified bentonite is better than other flocculants. The COD removal rate of monosodium glutamate wastewater, slaughtering wastewater and beer wastewater could reach 55.40%, 96.32%, 93.23% respectively. The treatment of slaughtering wastewater is the best and all treated effects meet the pretreatment requirement. Ammonium molybdate-modified bentonite is applied to several industrial effluents in different business. It is a new type flocculant with good flocculation effect and wide application.
