biological sludge meaning in Chinese
生物污泥
Examples
- Is suitable dehydration to each kind of sludge , like the biological sludge , chemistry sludge , contain oil the sludge and the coherent sludge and so on
适用于各种污泥之脱水，如生物污泥、化学污泥、含油污泥与粘性污泥等。 - Biosorption is a process that utilizes inexpensive active / dead biomass to sequester heavy metals and is particularly useful for the removal of contaminants from industrial effluents . compared with conventional methods such as ion exchange and precipitation with lime , the biosorption process offers the advantages of low operating cost , minimization of the volume of chemical and biological sludge to be disposed of , high efficiency in detoxifying very dilute effluents
生物吸附技术是环境领域近年来迅速发展起来的处理工业污染废水的新技术，它以各种生物(菌类或藻类)吸附废水中的重金属离子，具有吸附容量大，选择性强，效率高，消耗少，并能有效的处理含低浓度重金属离子废水等优点。 - 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。
