【摘要】：將高絮凝率菌劑YBJ-4應(yīng)用于西寧城市污水和大通河水的處理,以期得到較好的凈化效果。本研究采用單因素試驗(yàn)和正交試驗(yàn)對(duì)絮凝條件進(jìn)行優(yōu)化。結(jié)果表明:該株高效絮凝菌劑對(duì)大通河水凈化處理的最佳體系為絮凝劑加量1.2 mL,pH 7.0,助凝劑1.4 mL,處理時(shí)間25 min,最高絮凝率為95.43;對(duì)西寧城市污水的最佳絮凝體系為pH 6.8,1%的CaCl_2 1.2 mL,絮凝劑用量0.8 mL,處理時(shí)間15 min最高絮凝率為92.18%。經(jīng)過YBJ-4的凈化處理,西寧城市污水和大通河水水質(zhì)各項(xiàng)指標(biāo)的去除率均較高,即絮凝菌劑YBJ-4對(duì)西寧城市污和大通河水的凈化處理效果好。
[Abstract]:The high flocculation bacteria agent YBJ-4 was applied to the treatment of Xining municipal sewage and Datong river water. The single factor experiment and orthogonal test were used to optimize the flocculation conditions. The best system for purifying Datong River with high efficiency flocculant was 1.2 mL flocculant. The highest flocculation rate was 95.43, pH 7.0, coagulant 1.4 mL, treatment time 25 min; The best flocculation system for Xining municipal wastewater is CaCl_2 1.2 mL with pH 6.8%, and the dosage of flocculant is 0.8 mL. The highest flocculation rate of 15 min was 92.18%. The removal rate of Xining municipal wastewater and Datong river water quality index was higher after YBJ-4 purification. The flocculating agent YBJ-4 is effective in purifying Xining city sewage and Datong river water.
