聚乙烯醇+淀粉模拟退浆废水的小试处理研究
Study of simulated desizing wastewater(including PVA and starch)through laboratory trials
摘要
Abstract
Polyvinyl alcohol (PVA) and starch(the concentration ratio was 1 ∶ 2)were used to prepare the simulated wasterwater and hydrolysis acidification-aerobic process was used for the actual use.The results showed that the degradation of chemical oxygen demand (COD),polyvinyl alcohol (PVA),and starch was 89％～95％,89％～99％,and 85％～100％ respectivelly when the hydraulic retention time (HRT) was 24h,and the effect was better than HRT=12h (the degradation of COD,PVA,and starch was 70％～80％,52％～76％,and 81％～100％),especially the degradation of PVA.SVI was 50～200mL/g and there was no apparent affect of the Suspended Solid (SS) to the quality of water.The dissolved oxygen was about 0.2mg/(L · h) in the hydrolysis acidification pool and about 3mg/(L · h) in the aeration tank.关键词
