Processing method for stearate wastewater

一种硬脂酸盐废水的处理方法

Abstract

The invention discloses a processing method for stearate wastewater, and belongs to the technical field of wastewater processing. The stearate wastewater comprises zinc stearate wastewater and barium stearate wastewater. The concrete processing method for stearate wastewater comprises adjusting the pH value of zinc stearate wastewater to generate precipitate by employing ammonia water, and adding the adjusted zinc stearate wastewater with the amount being 1.5-2 times by volume of barium stearate wastewater into a barium stearte wastewater pool for combined processing. The uniformly-mixing time is 30 min, and finally the production wastewater, in other words, a transparent mixed solution only containing sodium chloride and sodium sulfate is obtained. By performing combination processing on zinc stearate and barium stearate wastewater, the barium stearate wastewater discharge problem is solved, the whole operation flow is simple, employed equipment is simple, and when environment is protected, the processing method possesses obvious economic benefit and environment benefit.
本发明公开了一种硬脂酸盐废水处理方法,属于废水处理的技术领域。本发明的硬脂酸盐废水包括硬脂酸锌废水和硬脂酸钡废水,其具体处理方法是采用氨水调节硬脂酸锌废水的pH值进而产生沉淀,将调节后的硬脂酸钡废水量1.5~2倍的硬脂酸锌废水加入到硬脂酸钡废水池中进行联合处理。其中混合均匀时间为30分钟,最后得到仅含氯化钠和硫酸钠,最后得到透明的混合溶液的生产废水。本发明通过联合处理硬脂酸锌和硬脂酸钡废水,解决硬脂酸钡废水排放问题,整个操作流程简便,所用设备简单,保护环境的同时,具有明显的经济效益和环境效益。
