A case study on biological efficiency enhancement of wastewater produced by a certain fiber limited company

1、 Project Overview

(1) Company Overview: A Fiber Production Company

(2) Wastewater type: Workshop wood pulp wastewater treatment

(3) Wastewater treatment capacity: 1200m3/d

(4) Treatment process: grid+coagulation tank+hydrolysis acidification+secondary aerobic tank+secondary sedimentation tank

(5) Customer demand: Improve the COD removal capacity of aerobic tanks

2、 Governance measures

Add our efficient bacterial strain (COD removal bacteria (aerobic)).

3、 Governance effectiveness

Our company's efficient COD removal bacteria were added to cultivate and domesticate the aerobic bacterial community in the system. At the same time, various parameters were adjusted according to the actual situation on site. After the data showed a downward trend, a gradient inflow method was adopted to gradually increase the system's processing load. After 8 days of debugging, the daily processing capacity of the system has reached the design standard, and the COD effluent also meets the discharge standard.
