| 工业固废的高含水量是导致处理成本高的主要原因 —— 湿污泥、湿煤泥不仅运输重量大,填埋时还需额外支付高额处置费。烘干环节的核心价值在于 “减量化”:通过间接加热或热风循环,将固废中的水分降至适宜范围,减少物料体积和重量,降低后续运输和处理成本。同时,烘干过程还能杀灭固废中的有害微生物,避免二次污染。比如某煤厂将湿煤泥烘干后,不仅运输量减少,还能与原煤混合燃烧,提高燃料利用率;某污水处理厂则将烘干后的污泥制成有机复合肥,其中的有害物质被有效去除,符合农业使用标准。此外,烘干设备的密封设计还能防止异味和粉尘扩散,满足环保要求,让企业避免因污染问题面临处罚。The high moisture content of industrial solid waste is the main reason for the high treatment cost - wet sludge and wet coal slurry not only have a large transportation weight, but also require additional high disposal fees during landfill. The core value of the drying process lies in "reduction": through indirect heating or hot air circulation, the moisture in solid waste is reduced to an appropriate range, reducing material volume and weight, and lowering subsequent transportation and processing costs. At the same time, the drying process can also kill harmful microorganisms in solid waste and avoid secondary pollution. For example, after drying wet coal slurry in a coal plant, not only does the transportation volume decrease, but it can also be mixed with raw coal for combustion, improving fuel utilization efficiency; A certain sewage treatment plant converts dried sludge into organic compound fertilizer, which effectively removes harmful substances and meets agricultural use standards. In addition, the sealing design of the drying equipment can prevent the spread of odors and dust, meet environmental protection requirements, and enable enterprises to avoid penalties for pollution problems. |
