| 中文摘要 |
| 通过改进传统水解池,强化水解池中的初沉污泥水解,以改善优质碳源比例. 强化污泥利用水解反应器集悬浮物的沉淀分离和污泥的水解酸化为一体,经强化污泥利用水解反应器处理后,废水中SS去除率达到81.4%,SS/BOD5由进水的2.4下降至0.4; SCOD/COD、COD0.45~5/COD分别提高了35.4%和17.7%,而COD>100/COD下降了53.2%; BOD5/TN从3.7提高至4.7; BOD5/TP从23.8提高至36.4. 废水的碳源结构得到了改善. 同时,在强化污泥利用水解反应器中完成了对污泥的处理,污泥水解率达到51.9%,实现了污泥的资源化与减量化. |
| 英文摘要 |
| In order to strengthen the sludge hydrolysis and improve effluent carbon source, the structure of currently existing hydrolysis reactor was reformed. The new process combined separation of suspended solids in influent and hydrolysis of settled sludge. Experimental results show that the removal rate of SS was 81.4%, the average SS/BOD5 ratio of effluent was dropped to 0.4,far less than that of the influent ratios; SCOD/COD and COD0.45~5/COD ratio of the effluent increased by 35.4% and 17.7%, but the COD>100/COD ratio reduced by 53.2%; BOD5/TN ratio increased from 3.7 to 4.7 and the BOD5/TP ratio from 23.8 to 36.4. The improvement of effluent carbon source was helpful for nitrogen and phosphorus removal in follow-up process. Meanwhile, the hydrolytic rate of sludge was up to 51.9%, realizing the reduction and resource-regeneration. |
