A case study on biological efficiency enhancement of aquaculture wastewater in a certain agricultural development limited company

1、 Project Overview

(1) Enterprise Overview: A certain agricultural development enterprise

(2) Wastewater type: aquaculture wastewater treatment

(3) Wastewater treatment capacity: 2000m3/d

(4) Treatment process: air flotation+two-stage AAO tank+secondary sedimentation tank+deep treatment

(5) Customer demand: Improve the COD removal capacity of the biochemical system

2、 Governance measures

Add our efficient bacterial strains (COD removal bacteria (aerobic), COD removal bacteria (anaerobic), and bacterial activation nutrient elements).

3、 Governance effectiveness

Adding our efficient COD bacteria and activating nutrients can greatly shorten the domestication cycle of COD bacteria. After a week of cultivation, the COD bacteria have adapted to the growth environment in the system and started to grow and reproduce normally. On the 7th day, the biochemical system has been established, and the effluent COD also meets the discharge standards.
