Product Introduction

The equipment-type integrated sewage treatment equipment is a new sewage treatment technology independently developed by Huapu on the basis of multi-stage biological contact oxidation process, combined with AAO and biological membrane process.

The maximum effluent of the equipment can stably meet the requirements of Class IV water quality standard.COD ≤ 30mg/L; BOD ≤ 6mg/L; SS ≤ 10mg/L; ammonia nitrogen ≤ 1.5mg/L; Total nitrogen ≤ 15mg/L; Total phosphorus ≤ 0.3mg/L)

Improved AAO/Contact Oxidation/MBBR/MBR Process

Applicable: large municipal sewage treatment plant, expansion, upgrading and reconstruction of water plant and emergency treatment.

未标题-1.jpgStable compliance

Mature technology, fully automated operation, easy management, stable and compliant effluent.

Cost economy

Adopting multi-stage aerobic and efficient precipitation processes, it has strong resistance to impact loads, small footprint, and low cost.

Intensive and compact

Underground installation, with a small footprint, is particularly suitable for areas with scarce land resources.

Intelligent reflux

The intelligent system adapts to regulate sludge reflux, significantly enhancing the efficiency of nitrogen and phosphorus removal.

sludge reduction

The new type of biological filler significantly enhances microbial activity and has a significant effect on reducing sludge.

Concept of intelligent control technology:Intelligent fine control technology, intelligent return technology, intelligent filtration technology and intelligent operation&maintenance management technology.

Equipment Selection

Underground type:

db463584-cb13-465f-819d-32a5b3725d14.png

Especially suitable for projects with scarce land resources, the ground can be used for greening and aesthetic purposes.

Ground container type:

c07b8a13-be1b-4d66-8886-57aed4cb32ff.png

Suitable for situations where terrain constraints prevent excavation of soil, resulting in a small amount of civil engineering work and a short construction period.

Scope of application: mainly applicable to emergency treatment of small domestic sewage and municipal sewage treatment plants with daily treatment capacity less than 1000m³/d, expansion and upgrading of water plants.

Installation mode: Full-buried, semi-buried and aboveground installation modes can be selected to meet different site conditions and project requirements and provide flexible and diversified solutions.

Equipment structure: continuous optimization through long-term practical experience, reasonable design and thorough consideration to ensure stable, reliable and excellent performance of equipment.

Construction period: less infrastructure works and short construction period, accelerate the project progress and reduce the impact on the surrounding environment.

Operation and maintenance: PLC controls full-automatic operation, greatly saving labor cost, reducing daily maintenance difficulty and improving equipment operation efficiency.

Investment cost: the investment cost is lower than that of the conventional steel concrete structure pool body, the early investment is effectively controlled, and the project economy is improved.
