摘 要:采用小试规模的膨胀颗粒污泥床反应器,研究营养元素对反应器内的颗粒污泥性能的影响及各种物质的适宜添加量,实验采用连续流,处理葡萄糖、啤酒配水,温度控制在中温(33±2)℃.实验结果表明,营养元素的添加量与污泥质量浓度相关,各种物质的适宜添加量分别为:NH4Cl为49.1mg/(gSS·d),KH2PO4为38.1mg/(gSS·d),FeCl2·4H2O为41.3mg/(gSS·d),CoCl2·6H2O为4.3mg/(gSS·d),NiCl2·6H2O为8.2mg/(gSS·d),CaCO3为7.5~13mg/(gSS·d),7Na2S·9H2O为22.7—56.7mg/(gSS·d).The bench-scale expanded granular sludge bed reactor is conducted in order to study the effect of nutrient element to granule sludge. Continuous flow is be used to treat dextrose and beer synthetically wastewater, and the temperature of reactor is controlled on medium temperature ( 33±2 ) ℃. The experimental results demonstrated that the additive quantity of nutrient element is correlative with the concentration of the granule sludge, and the fit additive quantity of nutrient element is following: NH4Cl is 49. 1 mg/(g SS · d), KH2PO4 is 38.1 mg/(g SS · d), FeCl2·4H2O is 41.3 mg/(g SS · d) ; CoCl2·6H2O is 4.3 mg/(g SS · d) ; NiCl2· 6H2O is 8.2mg/(g SS · d) ; CaCO3 is 7.5 -13 mg/(g SS · d) ; 7Na2S ·9H2O is 22.7 -56.7 mg/(g SS · d) , respectively.
