AI Technical Summary

Technical Problem

The prior art is difficult to effectively treat wastewater generated by the cabin washing station of various chemicals, especially due to the large differences in the characteristics of wastewater and the high treatment difficulty, resulting in unstable treatment effect. The accumulation of salts after wastewater reuse affects the system and equipment, limiting the wastewater. multiple recycling.

Method used

A comprehensive treatment and reuse system for washing wastewater in the cabin station of various chemicals was designed. The wastewater is realized through pretreatment devices of acid, alkali, benzene, oil, alcohol and domestic sewage, combined with biochemical and advanced oxidation processes. Classified pretreatment and deep treatment, high-pressure reverse osmosis and evaporation crystallization systems are used to remove salts to ensure that the treatment effect and reused water quality meet the standards.

Benefits of technology

The stable and standard treatment and multiple recycling of wastewater have been achieved, which reduces fresh water resource consumption, improves the reliability of treatment effect and the applicability of process, and reduces the impact of system salt accumulation on equipment.
