Technology goes overseas, nourishes Africa, Zhengzhong Technology completes wastewater treatment projects for beverage factories in two African countries

With the increasing global environmental awareness, the importance of sewage treatment has become increasingly prominent. As one of the leading environmental protection companies in the industry, Zhengzhong Technology has actively laid out its overseas territory relying on its strong product advantages and technological advantages. Many projects have been implemented in various continents around the world, contributing Chinese wisdom to creating a better environment for the world.

Recently, Zhengzhong Technology has built a comprehensive sewage treatment project for beverage factories for customers in African countries - Mali and Guinea. Zhengzhong Technology not only provides sewage treatment solutions according to local conditions, but also ensures the smooth progress of the project with its efficient and professional team configuration.

Project Overview

The main task of this project is to treat the carbonated beverage sewage generated daily. In view of the sewage characteristics of this project and combined with our company's many years of practical experience, Zhengzhong Technology adopts a "combination punch" treatment process. By integrating multiple processes and finely treating them in different processes, it ensures that the sewage is treated stably and efficiently. Process flow DAF (dissolved air flotation) + hydrolysis acidification + biological contact oxidation + precipitation + ozone oxidation

Process flow introduction

DAF (dissolved air flotation): through high-pressure dissolution and decompression to release microbubbles, adhere to suspended matter to form scum and remove it, achieve solid-liquid separation and purify water quality, and reduce harmful substances.

Hydrolysis acidification: convert difficult-to-degrade macromolecules into easily degradable small molecules, improve the biodegradability of wastewater, and facilitate subsequent treatment. A guide plate is installed in the pool to allow the organic matter in the wastewater to fully contact with microorganisms, react more fully, and save energy and be environmentally friendly.

Biological contact oxidation: Biological contact oxidation technology combines activated sludge with biofilm method, and uses fillers and aeration to promote microbial growth. As a carrier of microorganisms, the characteristics of fillers are crucial to the amount of biosolids, oxygen utilization, etc. Bottom aeration can accelerate the renewal of biofilms, maintain their high activity, solve blockage problems, and reduce energy consumption.

Precipitation: The effluent after biochemical treatment contains a large amount of dead and detached biofilms, etc., which require solid-liquid separation. The effluent from the biological contact oxidation tank enters the biochemical sedimentation tank for mud-water separation to clarify the mixed liquid.

Ozone oxidation: For the difficult-to-degrade caramel pigment contained in the sewage, ozone treatment can not only effectively oxidize and decolorize, but also disinfect and sterilize. In addition, ozone can remove odors and harmful substances in the water, and there are few by-products after disinfection. Through direct oxidation and decomposition to produce hydroxyl free radicals, the sewage is treated and discharged in compliance with the standards.

Equipment introduction

Zhengzhong Technology uses the enamel assembled tank developed independently as the sewage treatment equipment. The enamel assembled tank has excellent corrosion resistance and is suitable for treating carbonated beverage sewage. From production to installation, it is strictly implemented in accordance with the design plan to ensure that the quality meets the standards. And the on-site assembly method is adopted, which is simple and quick to install, thereby significantly improving the engineering efficiency and sewage treatment effect.

This project in Mali and Guinea not only reflects Zhengzhong Technology's profound accumulation in environmental protection technology, but also another important achievement of its overseas layout. As the global environmental protection industry continues to develop, Zhengzhong Technology will always adhere to its corporate philosophy and provide global customers with a full range of services from R&D, design, production to construction, and jointly promote the development of the global environmental protection industry.
