Embodiment Construction

[0023] The hydrazine hydrate by-product 5% salt water treatment and reuse method is to process the hydrazine hydrate by-product 5% salt water according to the following steps:

[0024] 1. Deamination

[0025] In a vacuum state, the solubility of ammonia in brine decreases as the temperature rises, and it is removed from the waste brine, and then condensed into dilute ammonia water. The temperature is controlled at 90-95°C, the pH value is 11-12, and the vacuum degree is -0.04. ~-0.06MPa. Send 5% brine to the spiral heat exchanger to heat up to 90-95°C, and then send it to the deammonization tower. If the temperature is less than 90°C, steam should be turned on, and the temperature of the brine will reach 90-95°C through the steam-water mixer, and then pass through the rotor The flow meter enters the deamination tower, and the removed ammonia gas is condensed into dilute ammonia water through the ammonia condenser, pumped into the dilute ammonia water pool by 2# ammonia water ...

Abstract

The invention discloses a recycling method of 5% by-product salt water of hydrazine hydrate in the waste water processing domain, which is characterized by the following: deaminating 5% salt water; oxidizing; draining salt water in the groove; supplying to electrolytic manufacturing system to reuse.

Description

technical field [0001] The invention relates to a method for treating and reusing hydrazine hydrate by-product 5% brine, which belongs to the field of wastewater treatment, in particular to a method for recycling and reusing hydrazine hydrate by-product 5% brine after treatment. Background technique [0002] At present, in the field of hydrazine hydrate production, the by-product 5% brine of hydrazine hydrate is generally discharged or sent to a special water treatment site. This method of treating 5% brine not only has the problem of wasting water resources, But also can cause certain influence to the environment, increased processing cost. Contents of the invention [0003] The object of the present invention is to provide a method for treating and recycling 5% brine by-product of hydrazine hydrate which can realize the reuse of 5% brine and save water resources, so as to turn waste into treasure and realize the repeated recycling of production water. [0004] The above...
