Desulfurization wastewater and slag water coupling system process
The invention relates to the technical field of electric power environment-friendly water treatment, in particular to a desulfurization wastewater and slag water coupling system process. According to the method, on the basis of the project background of zero discharge of wastewater in a whole plant and reduction of power generation water consumption, a synergistic action mechanism of desulfurization wastewater and ash water and a crystal action mechanism of ash and gypsum are researched and analyzed, and the desulfurization wastewater and an ash water system are designed to be coupled, desulfurization wastewater passes through a slag-water system and then is respectively used as process replenishment water for a slag conveyor and desulfurization, gypsum is hydrated and modified by bottom-discharged slag, and the problems of water replenishment and sludge treatment are solved. On-site design is carried out according to the research on different materials and key operation parameters, corrosion inhibition transformation is carried out on key parts related to a slag conveyor and a boiler, online visual operation control is carried out on the water treatment unit, and production accidents caused by equipment damage or pollution blockage and substandard water quality of the water treatment process are avoided. The process method has operability in wastewater gradient utilization and pollutant synergistic removal methods, is short in transformation period and low in cost, and has a wide application prospect.
本发明涉及电力环保水处理技术领域，具体涉及一种脱硫废水与渣水耦合系统工艺。本发明方法基于全厂废水零排放，降低发电耗水量的项目背景，通过对脱硫废水与灰渣水协同作用机理，以及灰渣与石膏的晶体作用机制进行研究分析，设计将脱硫废水与渣水系统进行耦合，提出脱硫废水通过渣水系统后分别作为捞渣机和脱硫的工艺补水，底排渣对石膏进行水化改性，解决补水与污泥处理的问题。根据对不同材质与运行关键参数的研究，对现场进行设计，在捞渣机及锅炉相关的关键部件上进行缓蚀改造，在水处理单元上进行在线可视化运行控制，避免因设备损坏或污堵，及水处理工艺水质不达标而造成的生产事故。该工艺方法，在废水梯级利用和污染物协同去除方法上具有可操作性，改造周期短费用低，具有广泛的应用前景。
