摘要
生活垃圾渗滤液是垃圾在收储和填埋过程中产生的具有较大污染物的污水,有机物含量较高,且含有较高重金属,属于危险废物。此类污水受城市区域分布及当地生活习惯影响较大,另外因目前垃圾分类尚未全面推广,导致终端焚烧或卫生填埋处理中垃圾种类和成分较复杂,此外垃圾渗滤液也受到当地垃圾性质、水文地质条件等环境因素影响较大,雨季产量较大,且水质水量均波动较大,给设计和处理带来很多不确定性。随着污水资源处理技术得到大力推广后,污水膜处理技术受到大力发展,其中DTRO因其回收率高;不容易发生二次污染;有充足的压力等优点,广泛应用于垃圾渗滤液处理厂、垃圾填埋场以及焚烧场、餐厨废水;渗滤液应急处理撬装一体设备;高浓度工业废水;浓缩液MVR蒸发前浓缩预处理等废水零排放治理工艺治理领域。
Landfill leachate is a kind of sewage with large pollutants produced in the process of garbage collection, storage and landfill. It contains high content of organic matter and heavy metals, so it belongs to hazardous waste. This kind of sewage is greatly affected by the urban regional distribution and local living habits. In addition, due to the lack of comprehensive promotion of waste classification at present, the types and components of waste in terminal incineration or sanitary landfill treatment are more complex. In addition, the landfill leachate is also greatly affected by environmental factors such as the nature of local waste and hydrogeological conditions. The output in rainy season is larger, and the water quality and quantity fluctuate greatly, which makes it difficult to supply Design and processing bring a lot of uncertainty. With the vigorous promotion of wastewater treatment technology, wastewater membrane treatment technology has been greatly developed, among which DTRO is widely used in landfill leachate treatment plant, landfill, incinerator and kitchen wastewater, skid mounted integrated equipment for leachate emergency treatment, high concentration industrial wastewater, and concentrated wastewater treatment due to its high recovery rate, less secondary pollution and sufficient pressure In the field of wastewater zero discharge treatment process, such as concentration pretreatment before liquid MVR evaporation.
