琥珀山庄居住小区污水处理工艺试验研究

The experimental studies of the process of the sewage treatment for the residential plot

进水 COD、油脂浓度过高 ,使小区污水处理厂难以正常运行 ,造成出水浑浊 ,不能达标排放。混凝沉淀试验证实 ,聚铝对 COD、油脂的去除率比聚铁高 ,在加药量达到 5 0 mg/ L时差异最为明显 ;水解酸化试验表明 ,水解酸化达到 2 h时 ,COD、油脂降解效果显著。采用物化法 ,可选用涡凹气浮工艺 ;采用生物法 ,可选用优点突出的水解酸化工艺。

The concentration of influent COD and grease were so high that the sewage-treatment plant of the residential plot could not get along normally and its effluent was easy to cause turbidity and could not reach the discharge standard. Through the coagulation sediment experiment, it was demonstrated that the removal effeciencies of COD and grease added ployaluminium chloride is higher than the removal effeciencies of COD and grease added ployferric sulphate, and between ployaluminium chloride and ployferric sulphate in the removal rate for COD and grease were significant difference when the amount of coagulant added was 50 mg/L. The hydrolysis-acidognosis experiment showed that the effect of COD and grease degraded was obvious when the time of hydrolysis-acidognos approached 2 h. If the phsicochemical method is adopted, the process of Cavitation Air Flotation may be chosen as a process. If the biological treatment way is used, the process of hydrolysis-acidognosis with outstanding advantage may be chosen as a process.
