Abstract

The invention discloses a treatment process for tuber mustard waste water, which comprises the steps that the waste water passes through a grid, a regulation tank, a dephosphorization settling tank, a hydrolysis acidation tank, an anaerobic contact tank, an intermediate settling tank and a CASS (Cyclic Activated Sludge System) tank in sequence, and reaches standards to be discharged. The treatment process removes organic matter and has stronger denitrification and dephosphorization functions; and the discharged water can meet a first-grade discharge standard of GB 8978-1996.

Description

technical field

[0001] The invention relates to a wastewater treatment process, which directly relates to the mustard mustard production wastewater treatment technique, in particular to the mustard mustard wastewater with high salt, high COD, high ammonia nitrogen and high phosphorus. technical background

[0002] Mustard mustard production wastewater has the characteristics of high salt, high ammonia nitrogen and high phosphorus, and direct discharge will have an impact on the water body and the surrounding ecological environment.

[0003] Most of the existing mustard wastewater treatment processes, such as:

[0004] (1) pH adjustment โ†’ grid โ†’ flocculation sedimentation โ†’ adjustment โ†’ anaerobic โ†’ primary contact oxidation โ†’ secondary contact oxidation โ†’ inclined tube sedimentation โ†’ discharge;

[0005] (2) Fine grid โ†’ regulation โ†’ compound anaerobic reaction โ†’ aerobic biofilm reaction โ†’ flocculation and sedimentation โ†’ discharge;

[0006] After the above process, the effl...
