Abstract

The invention discloses a sodium hypochlorite wastewater resource utilization treatment device and method. The device comprises a tubular ultrafiltration membrane system, a nanofiltration salt separation system, a reverse osmosis device, an evaporative crystallization device and the like, and resource utilization of sodium hypochlorite wastewater is realized through pretreatment and membrane system treatment. The treatment device and method disclosed by the invention are simple in process and low in water treatment and wastewater reuse cost, can effectively treat the sodium hypochlorite wastewater and realize recycling of water resources, and have relatively good economic and environmental benefits.

Description

technical field [0001] The invention belongs to the field of chemical production sewage treatment, and in particular relates to a treatment device and method for resource utilization of sub-sodium wastewater. Background technique [0002] In the current vinyl acetate production industry, the cleaning process of acetylene will produce a large amount of sodium hypochlorite wastewater (referred to as hyposodium wastewater), the main pollutants of which are phosphorus, suspended solids, colloids, and small molecule COD. Secondary sodium wastewater will be continuously discharged, with a daily discharge of about 100 tons. Due to the complex composition of pollutants in sub-sodium wastewater, the treatment is difficult, and the treatment process is highly dangerous, so it cannot be applied. Most enterprises recycle it, resulting in the production of high-concentration brine, which cannot be discharged. The content of phosphorus and chloride in the water quality increases, and lon...
