The biological treatment unit is the core component, often employing mature processes such as the activated sludge method or biofilm method. In the activated sludge process, a large number of microorganisms are in close contact with wastewater in the aeration tank, breaking down organic pollutants within the wastewater through their metabolic actions, converting them into carbon dioxide, water, and microbial cell material; the biofilm method utilizes microorganisms attaching to the surface of media to form a biofilm, where organic pollutants are progressively degraded as wastewater flows through the biofilm.

Integrated wastewater treatment equipment boasts numerous significant advantages. Firstly, it occupies minimal space, allowing the entire treatment process to be completed within a limited area, making it particularly suitable for areas with restricted space. Secondly, it is easy to install and can be flexibly moved and set up according to needs, significantly reducing the construction timeline. Moreover, it is highly automated, equipped with advanced control systems and sensors that can automatically monitor water quality, adjust treatment parameters, and control equipment operation, thereby minimizing human intervention and operational costs. Additionally, it delivers excellent treatment results, effectively removing organic matter, suspended solids, nitrogen, phosphorus, and other pollutants from wastewater. The effluent water quality is stable and reliable, playing an indispensable role in environmental protection and water resource recycling. It provides an ideal solution for addressing the wastewater treatment challenges in various locations.
