Integrated A/O equipment

Basic Principles

The integrated A/O equipment mainly includes a regulating tank, an anoxic tank, an aerobic tank, and a secondary sedimentation tank. Rural domestic sewage is first regulated for water quality and quantity through regulating tanks, and then undergoes nitrification and denitrification reactions through anoxic and aerobic tanks. The anoxic tank achieves denitrification and denitrification, while the aerobic tank removes carbon and ammonia nitrogen. Add chemical agents before the secondary sedimentation tank and use chemical methods to remove phosphorus. The remaining sludge is sent to the sludge concentration tank for sludge digestion, stabilization, concentration, and dewatering treatment. It is regularly transported outside to avoid secondary pollution.

technical advantage

Integrated A/O equipment is particularly suitable for small-scale sewage collection and treatment;

Automated operation, remote intelligent monitoring;

Convenient operation and management.

Applicable fields

Small scale, decentralized village and town sewage treatment;

Low to medium concentration wastewater with strong biodegradability.

Integrated MBR equipment

Basic Principles

The integrated MBR equipment mainly includes a regulating tank, an anoxic tank, and an MBR membrane tank. Rural domestic sewage flows through the regulating tank for uniform water quality and quantity, and then sequentially flows through the anoxic tank and the aerobic tank (MBR membrane tank) for biochemical treatment. The sludge load of MBR membrane tank is relatively high, which can achieve good treatment effect in a short residence time.

technical advantage

The solid-liquid separation effect is far superior to traditional sedimentation tanks;

Resistant to impact loads and stable effluent quality;

Small footprint, almost with site restrictions;

Automated operation, remote intelligent monitoring, and convenient operation management.

The PVDF membrane used has a long service life.

Applicable fields

Small scale, decentralized village and town sewage treatment points, recommended for use on a scale of 20-200 tons/day;

Artificial wetland treatment technology

Basic Principles

Select appropriate fillers based on the type of pollutants, and choose aquatic plants that use pollutants as their own nutrients and adapt to the local climate environment. Using fillers to adsorb ammonia nitrogen in water, activate insoluble phosphorus and adsorb it; Aquatic plants can enrich, transform, and decompose heavy metals in water bodies, breaking them down into harmless substances and degrading organic pollutants in water bodies. By regularly replacing fillers and harvesting plants, pollutants are ultimately removed from the system.

technical advantage

Low construction and operation costs; Not limited by the size of the venue, the scale can be large or small; Provide practical benefits such as greening and animal habitat.

Applicable fields

Suitable for sewage treatment in villages and towns with low population density and low pollution emissions.

Basic principles of biofilter technology

Select appropriate fillers to form a biological treatment structure, and use the microorganisms attached to the fillers to remove pollutants. According to the water quality and quantity, multi-stage filters are equipped to efficiently remove pollutants such as organic matter and nitrogen and phosphorus. Ventilation/sludge discharge system and supporting seepage structure are installed at the bottom of the biological filter tank; A water distribution system is installed inside the structure.

technical advantage

Good treatment effect, no secondary pollution; Fast start-up and strong resistance to impact loads; Automated operation, simple maintenance and management.

Applicable fields

Suitable for sewage treatment projects in villages and towns with severe terrain changes such as mountains and hills.
