Product Description
Unveiling the Revolutionary QDPP Integrated Sewage Treatment Solution
I. Defining Excellence in Sewage Treatment
The QDPP Integrated Sewage Treatment Equipment is a testament to Shandong Zhongqiao Enlightenment's unparalleled creativity and technological prowess. Constructed from state-of-the-art high-molecular materials, this equipment is meticulously engineered using advanced molding techniques to form a seamless, single-piece tank that exemplifies both durability and operational efficiency. Our ingenious R&D team has triumphantly overcome design challenges, refining Western technological principles to cater precisely to the unique sewage treatment needs of rural China. This innovation has birthed a versatile suite of integrated solutions, including the Zhong Qiao Tank Horizontal Tank A/B, Vertical Tank A/B, and the groundbreaking Hollow Tank, each tailored to ensure optimal performance.
II. Premium Raw Materials for Unmatched Performance
We select high-modulus polypropylene for its exceptional suitability in underground drainage and wastewater solutions. Its elastic modulus of ≥1500 MPa far exceeds HDPE's 800 MPa, offering unparalleled ring stiffness and structural integrity, essential for demanding high-performance applications.
Polypropylene is distinguished by its non-toxic, odorless, and highly crystalline characteristics, coupled with an ultra-light density (0.90-0.91 g/cm³) for superior water stability, indicated by a minimal absorption rate of 0.01%. With a molecular weight spectrum of 80,000 to 150,000, it ensures superior molding capabilities and a lustrous finish.
Showcasing outstanding chemical stability, polypropylene withstands a range of chemical agents, though it is sensitive to concentrated sulfuric and nitric acids and certain hydrocarbons. Its heightened crystallinity amplifies its chemical resistance, making it ideal for constructing robust, corrosion-resistant components.
Non-toxic and free of odor, polypropylene surpasses low-density polyethylene in strength, stiffness, and heat resistance, performing exceptionally at temperatures approaching 100°C. It also delivers excellent dielectric properties and high-frequency insulation that is unaffected by moisture.
Renowned for its broad resistance to common acids, bases, and organic solvents, polypropylene is perfect for use in food-grade utensils and applications.
PPH, a high molecular weight, low melt flow homopolypropylene, benefits immensely from β-modification, resulting in a fine crystalline structure that enhances its chemical and temperature resilience, creep resistance, and impact resistance at low temperatures.
III. Key Features that Define Distinction

4. Corrosion Resistance
It exhibits excellent resistance to various acids and bases and can store most organic and inorganic acids, bases, salts, and some organic solvents (see the corrosion data sheet for details).
5. Flexible and Convenient Installation Lightweight, easy to install and maintain, non-toxic, non-scaling, and non-contaminating. It is user-friendly, customizable according to customer needs, and allows for flexible overall installation. 6. Wide Application Range |
Our advanced equipment is engineered to cater to a vast array of industries, including wastewater management,
air pollution control, cutting-edge lithium battery technologies, chemical processing, metallurgy, electroplating,
textile production, dyeing industries, environmental conservation, oil refining, electronics, pharmaceuticals, food processing, oil extraction, light industry, acid production, acid cleaning, and
battery material manufacturing.
IV. Harmonizing Aesthetic Appeal with Functional Design
Equipment Color Palette: Primarily light gray, with customizable color options to cater to diverse aesthetic preferences.
Structural Configurations: Available in robust solid wall and innovative hollow designs to fulfill specific application needs.
V. Cutting-Edge Production Techniques
The QDPP Integrated Sewage Treatment Equipment is produced with an avant-garde one-time molding and multi-winding approach. Thicknesses vary from 10-80 mm, with the multi-winding process involving a strategic layering sequence of the base, cooling, and crystallization, followed by stress-relief and reheating before final winding. This procedure is meticulously tailored based on tank joint specifications and structural demands.
VI. Masterful Welding Processes for Seamless Integration
Our exceptional external welding process exemplifies the pinnacle of precision and strength. Leveraging state-of-the-art imported automatic extrusion welding machines, we achieve expansive welds precisely where the tank experiences the most stress-accomplished effortlessly in a singular operation. By using pristine PPH pellets, which perfectly match the tank's material, these are thermally fused at the seams, creating a robust, inseparable bond with the tank's bottom and body, ensuring unmatched durability and reliability.
