Example Embodiment

[0023] The 5% brine by-product of hydrazine hydrate is treated and reused according to the following steps:

[0024] 1. Deamination

[0025] In the vacuum state, the ammonia in the brine is removed from the waste brine as the temperature rises, and the solubility decreases, and then condensed into dilute ammonia. The temperature is controlled at 90~95℃, the PH value is 11~12, and the vacuum degree is -0.04. ~-0.06MPa. The 5% brine is sent to the spiral heat exchanger to be heated to 90~95℃, and then sent to the ammonia removal tower. If the temperature is less than 90℃, steam needs to be turned on, and the salt water temperature reaches 90~95℃ through the steam-water mixer, and passes through the rotor The flow meter enters the ammonia removal tower, and the removed ammonia gas is condensed into dilute ammonia through the ammonia condenser, and is pumped into the dilute ammonia pool with the 2# ammonia pump, and then sent back to the HH section by the 3# ammonia pump for reuse. Th...

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...
