Characteristics of Hydrazine Hydrate Wastewater

With the continuous development of China's industry, the manufacture of hydrazine hydrate has been rapidly developed, which has caused serious environmental pollution. Due to the lack of hydrazine hydrate wastewater treatment facilities, the wastewater from hydrazine hydrate processing is directly discharged into the water body without treatment, which not only affects the urban environment, but also ultimately affects the water quality of rivers. With the development of cities and towns, the increase of sewage will seriously affect the quality of life of the residents in the towns, and will also have a very adverse impact on the ecological environment on which we rely.

Hydrazine hydrate wastewater is characterized by high COD, high salt content, high alkalinity, high ammonia nitrogen and high biological toxicity. The water quality characteristics of the wastewater should be fully considered during treatment. If these pollutants are not properly treated, they will lead to serious environmental pollution once they enter natural water bodies and farmland, causing serious pollution of surface water, groundwater, soil and ambient air, and directly affecting people's health. The characteristics of hydrazine hydrate wastewater lead to great challenges in wastewater treatment. First, the high salt content directly eliminates biological methods. Traditional biochemical bacteria cannot tolerate such high salt content. Second, organic substances with high solubility. Because acetone propanol and water are highly miscible, adsorption with macroporous resin and activated carbon has no effect. Theoretically, the efficiency of membrane separation is also very low, and the current organic membrane cannot bear the dissolution characteristics of acetone, which will dissolve the membrane filament, packaging part, and even the membrane shell.
