浓缩果汁生产中的节水减污分析

浓缩果汁生产过程中消耗大量新鲜水,排放废水COD含量高,水质、水量波动大,传统的好氧处理方法难以取得理想效果。通过对几个典型浓缩果汁企业用水的调查和在线监测,从水量控制、废水减排、废水处理工艺等方面提出节水减污建议,实行清洁生产措施后,该企业耗水量减少了31.68%,排入污水站COD总量减少约20%。

ANALYSIS ON WATER SAVING AND POLLUTANT REDUCING IN PRODUCTION OF CONCENTRATED FRUIT JUICE

Water,acts as a basic source,was heavily dissipated in the process of concentrated fruit juice production,and then,poured as wastewater with high COD loadings.The wastewater from a fruit juice features large fluctuation in its quality and quantity,using traditional aerobic treatment technology is hardly fit for the great change.The water use of several local typical enterprises was investigated and online monitoring,was carried out,it was proposed some suggestins on water-saving and pollution-reducing from the control of water quantity,wastewater emissions,wastewater treatment technology.If these water saving and abatement proposals were put into practice,the water consumption of this company would be lowered by 31.68%,the total COD into the sewage station would be reduced by about 20%.
