Ion exchange resin regenerated and activated wastewater distillation and concentration treatment method

Abstract

The invention discloses an ion exchange resin regenerated and activated wastewater distillation and concentration treatment method which comprises the steps: treating activated wastewater by a reverse osmosis device, and respectively collecting wastewater clear liquid and wastewater concentrated liquid; S2, when the liquid level of the wastewater concentrated liquid in a water collecting well reaches 70-80% of the maximum value, turning on a standby water inlet valve and a power supply of a steam generator, and heating inlet water; and S3, when the steam pressure in the steam generator reaches a set value, turning on a steam outlet valve of the steam generator, and enabling heating steam to enter a heat exchange pipe of the evaporator; and meanwhile, starting a circulating pump, spraying the preheated wastewater concentrated liquid in the water collecting well into an evaporation chamber from the upper part of the evaporator for heat exchange, and circularly spraying and concentrating the wastewater concentrated liquid. The treatment method disclosed by the invention can realize resource utilization of the wastewater, 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...
