| titleOfInvention | A waste water zero discharge treatment system |
| abstract | The utility model relates to a wastewater zero-discharge treatment system, comprising a pretreatment unit, a membrane concentration unit, an evaporation crystallization unit, a solid salt treatment unit for sequentially treating raw wastewater, and a membrane concentration unit for collecting the The product water tank of the water produced by the evaporation and crystallization unit; wherein, the raw material wastewater is wastewater after aerobic treatment; the pretreatment unit includes a collection tank and an ultrafiltration device, and the membrane concentration unit includes a first connected in sequence. Reverse osmosis membrane equipment, high-density softened water tank, multi-media filter, nanofiltration equipment and second reverse osmosis membrane equipment, the evaporation and crystallization unit includes multi-effect evaporation and crystallization equipment; the first reverse osmosis membrane equipment is a sub-osmosis membrane equipment The utility model is the first time that the sub-permeable membrane and the medium and high pressure reverse osmosis are combined in the treatment of multi-source, mixed and complex waste water in industrial parks, so as to realize zero discharge of waste water, waste gas and waste residue. |
