摘要
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。
This paper analyzes the common characteristics of natural gas purification wastewater and researches anaerobic biodegradation of the wastewater through cultivating it.It shows that the anaerobic treatment is not suitable for alkalinity.Carbonate alkalinity of the wastewater should be adjusted to 3000~8000mg/L to make anaerobic reactor run correctly.Due to lacks of nutriment and phosphor,the wastewater should be supplemented according to CODcr∶N∶P=(200~300)∶5∶1.It also shows the wastewater can be treated in anaerobic biodegradable way and the BD% can reach as high as 64%.But wastewater has to be diluted beforehand or be taken measure to deprive it poison.
