Wastewater Treatment Technology

Water pollution is the focus of discussion in today's society. In order to make industrial wastewater reach the discharge standard, many factories have used sewage treatment equipment.

Reasons why the effluent of the integrated water treatment equipment does not meet the standards:

Inclined plate (tube) sedimentation tank is based on the principle of horizontal flow sedimentation tank.

In sludge filter press treatment, these agents can be divided into the following categories according to their different uses:

The role of aerobic tanks in wastewater treatment is to allow activated sludge to perform aerobic respiration, further decompose organic matter into inorganic matter, and remove pollutants. Good operation requires controlling the oxygen content and other conditions required by microorganisms to be optimal, so that microorganisms can perform aerobic respiration with the greatest efficiency.

How to treat industrial wastewater

A2/O process is the abbreviation of Anaerobic Anoxic Oxic, which is the abbreviation of biological nitrogen and phosphorus removal process. The treatment efficiency of this process can generally reach: BOD5 and SS are 90%~95%, total nitrogen is over 70%, and phosphorus is about 90%. It is generally suitable for large and medium-sized urban sewage plants that require nitrogen and phosphorus removal

In the field of sewage treatment, accurate addition of carbon source is one of the key factors to ensure stable and efficient treatment effect. However, excessive addition of carbon source is a common operational error, which may trigger a series of chain reactions and affect the stability and effluent quality of the entire sewage treatment system.

In the process of sewage treatment, we often encounter the phenomenon that the activated sludge in the aeration tank does not grow or even decreases. What is the reason? And how to solve it?

With the advent of winter, the temperature gradually drops, which has a significant impact on the sludge activity in the sewage treatment process. In low-temperature environments, microbial activity weakens and the biodegradability of sludge decreases accordingly, thus affecting the efficiency and stability of the entire sewage treatment system.
