1.
This paper analyzes the common characteristics of natural gas purification wastewater and researches anaerobic biodegradation of the wastewater through cultivating it.
对天然气净化废水的一般特性进行了分析,同时采用培养法对天然气净化废水厌氧生物降解性进行了研究,结果表明:该废水的碱度不在厌氧处理的范围内,在进行厌氧处理时须调节其碳酸盐碱度,使其在3000～8000mg/L的范围内,才能满足厌氧反应器的正常运行,废水的营养物质及磷元素缺乏,废水处理时应按照COD∶N∶P=(300～500)∶5∶1的比例添加营养物质及磷盐;废水可进行厌氧生物处理,其厌氧可生物降解性BD最高可达64%,但在厌氧处理时必须进行稀释预处理或采取适当的脱毒措施。
