Abstract:

Wastewater from small-scale preserved Szechuan pickle processing plant is organic wastewater containing high salinity and ammonia/nitrogen. Regulating tank-primary settling tank-contact anaerobic pool-pool process has been used. After debugged for 75 days, the effluent water quality can reach the standard. The system has been running steadily for a year. The process is characterized by simple technique, easy operation and suitable for the treatment of wastewater from small-scale enterprise production whose drainage is irregular.

Key words: wastewater from preserved Szechuan pickle processing, high salinity, high ammonia/nitrogen

摘要：

小型榨菜加工厂废水为高盐分、高氨氮的有机废水，采用调节池—初沉池—接触厌氧池—CASS池工艺处理，调试75 d后出水达标，系统已稳定运行一年。该工艺简单、操作简便、可适应小型企业生产排水不规律的废水治理。
