摘要
本研究将垃圾焚烧发电厂储坑渗滤液视做可再生资源,其与碱处理后的秸秆进行的中温混合厌氧消化表现出典型的水解酸化和甲烷化过程。高浓度储坑渗滤液能产生相对较高的VFA,可提高系统的产气率和产气量。其产气率比未加入渗滤液的厌氧消化系统高出60.15m L/g VS,总产气量高出1868m L。表明该储坑渗滤液可与碱处理后秸秆混合进行再生能源化利用。
The study regards leachate from waste incineration plant storage pit as renewable resources and conducts medium temperature anaerobic digestion mixed with straw treated by base. In the hydrolysis acidification stage, the text added high concentration of leachate increases higher content of VFA, but not influences the reaction system into methane - producing stage. And the high concentration of leachate can promote the gas - production rate and gas production of the mixed anaero- bic material, gas -production rate is 60.15mL/gVS higher, and total gas production is 1868 ml higher. The Study shows that the comprehensive utilization of the mixed high concentration of leachate regarded as a kind of high concentration, compli- cated composition organic wastewater with straw treated by base is feasible.
