某麦芽生产厂废水管理与处理实践研究

Wastewater Management and Treatment Practice of A Malt Factory

麦芽生产过程包括清选、浸麦、发芽、烘干以及除根等工序,废水主要来自于浸麦、发芽等工序。某麦芽生产厂根据麦芽过程用水和废水产生的特点,采用设备改进、加强工艺管理、用水管理、废水回用、提高员工技能等措施,通过源头削减和生产全过程控制,合理调节生产用水,降低生产用水量和废水产生量,麦芽生产水耗指标为2.4 m3水/吨麦芽。麦芽废水采用SBR工艺进行处理,出水水质满足排放标准要求。该麦芽企业废水管理和处理经验为同行业提供了较好的案例。

The malt production process is consisted of cleaning, steeping, germinating, baking, and disrooting. According to the characteristics of water usage and wastewater production process, the malt factory take the measures of improving equipment, strengthening management on technology and water usage, recovering wastewater and upgrading technical skill, etc. to properly to reduce water consumption and the amount of wastewater. Water consumption is 2. 4 m3 water/ton after adopting source reduction and production process control. The process of SBR was taken to treat the wastewater from malt production, the water quality of effluent met discharge standard. The experience of wastewater management and treatment in the malt factory provided reference for other factories.
