Distillation concentration treatment method for ion exchange resin regenerated and activated wastewater

Abstract

The invention discloses a method for treating ion-exchange resin regenerated and activated wastewater by distillation and concentration, which includes treating the activated wastewater through a reverse osmosis device, and collecting respectively the wastewater clear liquid and the wastewater concentrated liquid; S2: the liquid level of the waste water concentrated liquid in the water collection well reaches the maximum value 70‑80% of the steam generator’s standby water inlet valve and power supply, and the water is heated; S3: When the steam pressure in the steam generator reaches the set value, open the steam generator’s outlet valve, and the heating steam enters the evaporator for replacement In the heat pipe; at the same time start the circulating pump, the preheated wastewater concentrate in the water collection well is sprayed from the upper part of the evaporator to the evaporation chamber for heat exchange, and the wastewater concentrate is sprayed and concentrated in a circular manner. The treatment method disclosed by the invention can realize resource utilization of waste water, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a distillation and concentration treatment method for ion exchange resin regeneration and activation wastewater. Background technique [0002] As the primary product of plant photosynthesis, biological sugar is widely distributed in organisms. The biological sugar in plants has a variety of biological activities and has little toxic and side effects. At present, the main extraction method of biological sugar is acid hydrolysis. And deacidification, decolorization, concentration, ion exchange, hydrogenation and other processes to obtain relatively pure biological sugar, this process consumes a large amount of chemical raw materials and produces a large amount of wastewater; the current treatment process of activated wastewater consumes a large amount of heat energy and water resources , causing huge economic pressure on the enterprise, and the treated wastewater can only meet t...
