Against the backdrop of rapid urban expansion and sustained population growth, domestic wastewater pollution has become an increasingly tough challenge worldwide. Adopting efficient and eco-friendly sewage disposal solutions not only guarantees residents’ quality of life, but also exerts a direct influence on the long-term sustainability of ecological environments. This paper explores mainstream cutting-edge domestic wastewater treatment technologies at present, and focuses on the innovative practices and exclusive technical strengths of Haipuou Environmental Protection Group within this industry.

一、The Vital Significance of Domestic Sewage Treatment

Domestic wastewater mainly originates from households, commercial premises and public facilities, containing massive organic pollutants, nitrogen and phosphorus nutrients, as well as pathogenic microorganisms. Discharging untreated or incompletely treated sewage into natural water bodies will trigger eutrophication, severe water quality degradation and even public health risks. For this reason, high-performance sewage treatment technologies are absolutely essential.

(一) Practical Suggestions

1. Government side: Increase investment in sewage treatment infrastructure and roll out stringent effluent discharge standards.

2. Enterprise side: Deploy state-of-the-art sewage treatment technologies and equipment to boost purification capacity and treatment performance.

3. Public side: Heighten environmental awareness, cut down pollutant discharge and take an active part in water resource conservation activities.

二、Mainstream Advanced Domestic Sewage Treatment Technologies

(一) Activated Sludge Process

As one of the most widely adopted domestic sewage treatment technologies globally, the activated sludge process purifies wastewater through the biodegradation of organic contaminants by microorganisms. Based on this classic process, Haipuou Environmental has carried out multiple technical renovations to lift overall treatment efficiency and system stability.

Technical Parameters & Performance Assessment

1. Treatment efficiency: Haipuou’s activated sludge system can remove more than 90% of BOD5 and COD pollutants.

2. Operating cost: Optimized process flow and intelligent energy management cut operational expenses by over 15%.

3. Practical project verification: After being put into service at a municipal sewage plant, this technology raised the daily treatment capacity by 30%, with outlet water fully complying with National Class A Discharge Standard of China.

(二) Membrane Bioreactor (MBR)

The MBR technology organically combines biological treatment and membrane separation, which can effectively intercept suspended solids and macromolecular organic matter in sewage. Haipuou Environmental has achieved remarkable technical achievements in the research and application of MBR equipment.

Technical Parameters & Performance Assessment

1. Treatment effect: The MBR system achieves a removal rate of up to 99% for suspended solids and over 80% for total nitrogen and total phosphorus.

2. Land occupation: The floor space required by the MBR system is reduced by 40% compared with the traditional activated sludge process.

3. Practical project verification: Deployed in the sewage treatment project of a large residential community, the MBR system not only improved purification performance, but also greatly lowered daily operation costs.

(三) Digital Twin Smart Water System

Independently developed by Haipuou Environmental, the digital twin smart water system realizes intelligent whole-process management and optimized scheduling of sewage treatment by virtue of big data and cloud computing technologies.

Technical Parameters & Performance Assessment

1. Multi-dimensional data collection: Collect real-time operational data throughout the sewage treatment workflow, including water flow, water quality indicators and energy consumption.

2. AI intelligent analysis: Adopt algorithm models to process massive operational data, predict potential equipment faults and adjust running parameters automatically.

3. Practical project verification: After the system was launched in a municipal wastewater plant, the facility’s energy consumption was reduced by 20% and equipment maintenance expenditure dropped by 10%.
