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
