This paper comprehensively comments the stack gas desulfurizer of the p resent mid and mini - type boiler at home , comments the lectotype attention items of stack gas desulfurizer when boilers are being designed and renovated , introduc e s a kind of new type desulfurized products - desulfurized stack , provides perfect products for the existing boiler ' s desulferized renovation 该文对国内现有的中小型工业锅炉的烟气脱硫器进行了综合述评,论述了在锅炉房设计和改造时烟气脱硫器的选型注意事项,同时介绍了一种新型烟气脱硫产品- -脱硫烟筒,为现有锅炉房的脱硫改造提供了适用产品。
An integrated process of wastewater treatment and utilization is presented . the process is made up of heating the soft water of room temperature by high temperature printing and dyeing wastewater via heat exchangers , reusing the low level base decrement wastewater of water washing for dust control and desulphurizing of stack gas and anaeration - aeration biological treatment of printing and dyeing wastewater . this process has fair economical benefit on the principle of so called waste control by waste itself . this might be an ideal process for printing and dyeing wastewater treatment and disposal , the effluent of this process is quite enough to meet the requirement of urban sewer collector . additionally also many advantages are attractive such as the complete return of biological sludge to digestion , no chemicals dosage and free of secondary pollution 介绍了高温印染废水通过热交换加热常温软水、低浓度碱减量水洗废水用于烟道气除尘脱硫、厌氧-好氧处理一般印染废水等印染废水综合处理技术,该技术具有较好的经济效益,达到了以废治废的目的,生物污泥全部回流硝化,不加任何药剂,无二次污染,处理后水质达到城市截污管网标准要求,是一种较为理想的印染废水处理工艺。
