Overview

Domestic sewage refers to the wastewater generated in daily life by residents, mainly including water from washing, bathing, kitchen waste, and sanitary ware drainage, containing pollutants such as organic matter (BODs, CODc), suspended solids (SS), nitrogen, phosphorus nutrient salts, and pathogenic microorganisms. Its water quality is complex and prone to decay. If it is directly discharged without treatment, it will lead to eutrophication of water bodies, black and odorous water, and the risk of disease transmission. It is necessary to achieve up-to-standard discharge or resource recovery through efficient treatment to ensure ecological environment and public health safety.10694b6d-32ea-4ae5-9c8d-f2095d2f765b.png

System Advantages

1. Smart control

Intelligent hub: Real-time monitoring via the Internet of Things, optimized operation with big data in the cloud, precise regulation of aeration and chemicals, achieving energy savings of over 30%. Multi-parameter sensing: Real-time feedback of water quality data such as COD, BOD, NH3-N, TN, TP, automatically matching the optimal treatment plan.

2. Efficient process

MBR+Multi-stage A²/O Process: Membrane Bioreactor Technology + Enhanced Nitrogen and Phosphorus Removal, with Hydraulic Retention Time Reduced to 6-10 Hours. Ultra-low Energy Consumption: Energy-saving Fan + New Aeration, with Oxygen Utilization Rate Above 35%, and Energy Consumption Reduced by 30%.

3. Modular design

Q235/304 stainless steel/FRP multi-material options, corrosion-resistant and low-temperature resistant, occupying only 1/3 of the space required by traditional processes, and supporting rapid assembly and expansion.


Scope of Application

1. Domestic sewage: Collection and treatment of domestic drainage from enterprises, institutions, public facilities, villages, and towns.

2. Industrial wastewater: Secondary biochemical treatment of industrial wastewater from food processing, aquaculture, slaughtering, brewing, etc.

3. Ecologically sensitive areas: scenic spots, islands, and service areas, supporting reclaimed water reuse.

4. Emergency response: rapid deployment in containerized form.
