The service life of integrated sewage treatment equipment is affected by various factors, generally around 10 to 20 years.

Hospital wastewater contains a large amount of pathogens (such as bacteria, viruses, etc.), organic matter, heavy metals, and other substances that may pose a threat to the environment or human health. Wastewater treatment equipment effectively removes these harmful substances through physical, chemical, or biological methods, ensuring that wastewater meets safety standards before discharge.

The integrated sewage treatment equipment adopts membrane bioreactor technology, which is a new process combining biological treatment technology and membrane separation technology, replacing the traditional secondary sedimentation tank for wastewater treatment. It can efficiently perform solid-liquid separation and obtain stable wastewater for direct use. It can also maintain a high concentration of microorganisms in the biological pool, with minimal residual sludge in the process, effectively removing ammonia nitrogen. The suspended solids and turbidity in the effluent are close to zero, and the bacteria and viruses in the effluent are greatly removed, resulting in low energy consumption and small footprint.

Wastewater quality. The quality of domestic sewage is usually relatively stable, and general treatment methods include acidification, aerobic biological treatment, disinfection, etc. The reasonable selection of process flow for industrial wastewater should be based on specific water quality conditions. It should be noted that when using aerobic biological treatment technology to treat wastewater, attention should be paid to the biodegradability of the wastewater. Anaerobic biological hydrolysis acidification can also be carried out to improve the biodegradability of wastewater, or non biological physical or chemical methods can be considered for treatment.

Based on different water quality treatment objectives and core reaction principles, the process route of integrated wastewater treatment equipment exhibits diversified characteristics. Among them, biological treatment processes have become mainstream due to their low cost and good environmental performance. Combined with different scenario requirements, various mature solutions have been derived:

Modern urban sewage treatment equipment has moved away from the traditional "extensive" treatment mode and is developing towards high efficiency, intelligence, and energy conservation. Its core technical features are reflected in the following aspects:
