ABSTRACT
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 COD(0.45-5)/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.
