摘要
为考察沼液浸泡用于油泥砂和玉米秸秆共消化的可行性,并作为新的处理技术参与实际应用以解决当前石油开采、冶炼过程中的危险废物油泥砂的污染问题以及提高共消化产气性能,开展了沼液浸泡底物对共消化产气性能的影响试验。结果表明:单一油泥砂由于缺乏有机物质,预处理对其有机组分改变不大,不适合作为消化底物进行产气;经沼液浸泡的玉米秸秆物理-化学性质得到改善,更易被微生物降解利用。综合各项产气结果,当浸泡率为70%,处理24h后的玉米秸秆与油泥砂的消化产气结果最佳,累积产气量1077mL,单位有机质产气量为7.96mL/gVS,容积产气率为0.68(L//L·d)。该项研究结果可为油泥砂的合理处置提供参考依据。
For biogas digested soaking for oil sludge sand and the feasibility of corn stover were digested,and partici pated in the practical application as a new processing technology in order to solve the current hazardous waste sludge in the process of oil exploitation,smelting the pollution problem of sand and improve the performance of a total of di gestive gas test with the method of biogas slurry soaking substrates,focuses on biogas digested soaking effect on the performance of a total biogas.The results showed that the single oil sludge sand was not suitable for gas production because of the lack of organic substances,and the pretreatment has little effect on its organic composition.The phys ic-chemical properties of the corn stover soaked in biogas slurry were improved,which can be easily degraded and utilized by microorganisms.According to the comprehensive biogas production results,when the soaking rate was 70%,the digestion gas production results of corn straw and oil sludge sand after 24 h treatment were the best,with the cumulative gas production volume of 1077 mL,the gas production per unit of organic matter of 7.96 mL/g VS,and the volume gas production rate of 0.68(L//L·d).The results of this study can provide reference for the reason able disposal of oil sands in enterprises.
