厌氧消化处理非木材纤维纸浆中杂细胞工艺研究

摘要

对慈竹纸浆中杂细胞进行厌氧消化处理，结果表明，TS去除率达68.64%，原料产气率299.9mL/gTS，日均产气率4.998mL/(gTS*d)，池容产气率0.3224m3/(m3*d)，CH4含量64%。对发酵上清液进一步处理结果为：COD去除率53.69%，CH4含量67%，N、P去除微弱。在此基础上，进行了物料平衡和COD利用率计算。%A batch anaerobic digestion was used to treat Parenchyma Cell of bamboo. The result shows: TS removal rate reaches 68.64%, the gas production rate of raw material 299.9mL/gTS, the rate of gas production 0.3224m3/m3 slurry a day. After 60 days operation, the content of CH4 in the biogas is 64%. Effluent water from the improved UASB digester was digested in the multi-grade anaerobic digester. The results are: average COD removal rate reaches 53.69%, CH4 content of biogas 67%, the rate of N and P removal low. Materials balance and COD utilization ratio is calculated based on the experimental results.
