Abstract

The invention discloses an air circulation high-salinity wastewater desalination treatment system which comprises a solar integrated heat collection-evaporator, an air regenerator, a water cooler, a waste liquid supplementing tank, a condensate water recovery tank, an air pump, a bubbler and a butterfly air valve, and an air circulation flow path, a wastewater flow path, a condensate water flow path and a cooling water flow path are formed by the system. Through the integrated solar heat collection-evaporator, the heat collection process and the evaporation process of wastewater are integrated and unified, solar radiation heat is directly used for evaporation mass transfer, the cost is saved, meanwhile, heat loss is reduced, the system treatment efficiency is improved, and efficient and clean desalination and recovery of high-salinity wastewater are achieved.

Description

Technical field [0001] The present invention relates to a high-salt wastewater desalination treatment system. Background [0002] With the gradual advancement of the industrialization process, the problem of water pollution, especially the pollution of industrial wastewater, has become increasingly prominent. As an important part of industrial wastewater, high-salt wastewater is widely present in various chemical production processes, including coal chemical industry, dye production, pesticide production, etc. Since the salt content of high-salt wastewater is higher than 1%, high salt content will become a microbial inhibitor and toxic agent, greatly increasing the difficulty of biological treatment, therefore, the current conventional sewage treatment widely used biological treatment technology can not effectively treat such wastewater. [0003] Evaporation treatment technology is widely used in the field of water treatment because of its wide range of use and is not limited by ...
