Wastewater integrated equipment is a comprehensive unit that integrates the collection, treatment, discharge, or reuse of wastewater. It employs advanced technology and processes to integrate multiple treatment units into a compact device, achieving effective wastewater management and resource recycling.

The working principle of the integrated wastewater treatment equipment primarily relies on the comprehensive application of physical, chemical, and biological treatment methods. The equipment typically includes multiple units such as pretreatment, biological treatment, and post-treatment, which work together to achieve wastewater treatment.

Pre-treatment Unit: Primarily removes large suspended particles, oils, and other settleable substances from wastewater to alleviate the burden on subsequent treatment units. Common pre-treatment units include grates, regulating basins, etc.

Biological Treatment Unit: Utilizes the metabolic action of microorganisms to convert organic matter in wastewater into harmless substances. This unit typically employs biological membrane reactors, activated sludge reactors, and other biological treatment devices, which, through the attachment and growth of microorganisms, effectively degrade wastewater.

Post-treatment unit: Further removes harmful substances and impurities from wastewater to meet discharge standards or recycling requirements. The post-treatment unit may include sedimentation ponds, disinfection ponds, filters, etc.
