微波预处理复杂废水的研究

Study on complex wastewater by microwave pretreatment

本文用微波预处理复杂废水,研究了微波预处理对复杂废水的处理效果。结果表明,微波预处理对复杂废水中污染物有一定的去除效果,微波作用复杂废水时CODcr、氮氮及BOD_5的去除率变化曲线呈先逐渐增大后趋于平缓,微波处理超过10min COD_(cr)、氮氮及BOD5的去除率分别达到46.68%、40.11%和28%。经微波预处理后复杂废水的B/C比增加,由0.032增大到15min的0.23,明显改善复杂废水的可生物降解性。

Complex wastewater had been pretreated by microwave. The results showed that CODcr ,BODs and nitrogen of complex wastewater had been removed by microwave pretreatment. The removal rates increased with microwave time, which removal rates of CODor ,BOD5 and nitrogen reached 46.68%, 40.11% and 28% respectively at more than 10 min. B/C ratio of complex wastewater increased from 0.032 to 15 min 0.23h is obvious that microwave pretreatment has made complex wastewater to be biodegradable
