Product Overview

The LINZHEN MBBR Corrugated Package Sewage Treatment Unit developed by Qingdao Linzhen Environment Project Co., Ltd. is a fully integrated, modular wastewater treatment solution based on advanced Moving Bed Biofilm Reactor (MBBR) technology.

Designed for municipal sewage treatment, industrial wastewater treatment, decentralized wastewater projects, and water reuse applications, this containerized treatment system integrates multiple processes including equalization, biological degradation, solid-liquid separation, filtration, and disinfection into one compact and transportable structure.

Unlike traditional concrete wastewater treatment plants that require long construction periods, complex civil engineering, and high installation costs, the LINZHEN corrugated containerized wastewater treatment system is:

• Factory manufactured
• Fully assembled
• Pre-piped and pre-wired
• Factory tested before shipment

After delivery, customers only need to complete foundation preparation, utility connection, and commissioning, reducing installation time from months to weeks.

With customized designs based on wastewater characteristics, treatment capacity, discharge standards, installation space, and local environmental regulations, LINZHEN provides reliable turnkey wastewater treatment solutions for customers worldwide.

What Is an MBBR Integrated Treatment Unit?

An MBBR Integrated Wastewater Treatment Unit is a compact packaged sewage treatment system that combines Moving Bed Biofilm Reactor technology with sedimentation, filtration, and disinfection processes inside a single containerized structure.

The system utilizes specially designed biofilm carriers as a growth medium for microorganisms. These carriers move freely within the aerated reactor, allowing microorganisms to efficiently degrade organic pollutants and remove nitrogen compounds.

By combining suspended growth and attached growth biological treatment, MBBR technology provides:

• Higher biomass concentration
• Excellent resistance to shock loads
• Stable effluent quality
• Reduced sludge bulking problems
• Smaller installation footprint
• Lower maintenance requirements

The integrated design makes it an ideal solution for locations where construction time, land availability, and operating costs are critical factors.

Core Process: MBBR Moving Bed Biofilm Reactor Technology

At the heart of the LINZHEN package sewage treatment unit is the advanced MBBR biological treatment process.

The system uses specially engineered plastic bio-media carriers with complex internal structures and large protected surface areas. These carriers provide an ideal environment for microorganisms to attach, grow, and form stable biofilms.

During operation:

1. Wastewater enters the biological reactor.
2. Bio-media carriers remain suspended through continuous aeration.
3. Microorganisms attached to the carriers degrade organic pollutants.
4. Nitrogen compounds are removed through biological nitrification and denitrification.
5. Treated wastewater proceeds to clarification, filtration, and disinfection.

Process Flow

The system follows a multi-stage treatment path to produce discharge-quality or reusable effluent:

Equalization Tank — Balances flow and pollutant concentration.

MBBR Tank 1 — Primary biological degradation via suspended biofilm carriers.

MBBR Tank 2 — Secondary polishing of BOD, COD, and ammonia nitrogen.

Lamella Settler — Inclined plate settling for solid-liquid separation.

Treated Water Collection Tank — Stores clarified water before polishing.

Pressure Sand Filter (PSF) — Removes residual suspended solids.

Activated Carbon Filter (ACF) — Adsorbs organics, color, and odor.

UV Disinfection Unit — Chemical-free pathogen inactivation.

Clean Water Storage — Holds final treated water for discharge or reuse.

Key Technical Characteristics

The LINZHEN MBBR Integrated Treatment Unit is engineered around four core design principles:

• Process Integration — Seamlessly combines pretreatment, biological treatment, solid-liquid separation, filtration, and advanced disinfection in one continuous process.

• Synergistic Effects — Maximizes treatment efficiency through optimal collaboration between process units, ensuring stable performance under varying loads.

• Compact Design — Saves 30–50% of space compared to traditional processes, making it ideal for confined sites and mobile applications.

• Automated Operation — Enables intelligent control through integrated PLC automation, minimizing manual intervention and labor costs.

Construction Quality & Internal Components

The unit is housed in a corrugated steel container that provides enhanced structural rigidity and durability for transportation and long-term outdoor operation. The container shell is sandblasted to create a uniform rough surface, then coated with a triple-layer anti-corrosion system — zinc-rich primer, intermediate epoxy coat, and protective top coat — ensuring strong adhesion, excellent rust resistance, and long-term surface protection.

The movable structural design of the control room makes it easier to maintain or relocate during equipment replacement or system expansion.

Internal Components

Basic Configuration

The system is composed of seven integrated treatment units:

1. Primary Sedimentation Tank — Removes settleable solids and reduces organic loading.

1. Anoxic Tank — Provides denitrification conditions for nitrogen removal.

1. Contact Oxidation Tank — Houses MBBR bio-media for aerobic biological treatment.

1. Secondary Sedimentation Tank — Separates biomass and suspended solids from treated water.

1. Disinfection Tank / Unit — Houses UV or chemical disinfection equipment.

1. Sludge Tank — Collects and temporarily stores excess sludge.

1. Blower Room — Contains air blowers, pumps, and electrical control panels.
