Wastewater From Chemical Industry

Technical Background

Industrial wastewater refers to the wastewater and waste liquids discharged during industrial production processes, containing industrial raw materials, intermediate products, by-products, and pollutants generated during production, which are important causes of environmental pollution, especially water pollution. To advance chemical wastewater treatment, China has issued a series of policy documents, including the "Guiding Opinions on Promoting the Utilization of Sewage Resources", "Implementation Plan for the Recycling of Industrial Wastewater", and the "Action Plan for High-Quality Development of the Environmental Protection Equipment Manufacturing Industry (2022-2025)". These documents outline the overall requirements, key tasks, and support measures for the resource utilization of sewage and the recycling of industrial wastewater, emphasizing the need to enhance the supply of efficient, low-carbon environmental protection equipment and products.

Technical Introduction

Leveraging its strengths in container manufacturing, CIMC Environmental introduces the concept of modular construction by integrating water treatment units such as pretreatment, biochemical treatment, and advanced treatment into independent modules. These modules, built with steel structures, are prefabricated in factories to create efficient and low-carbon industrial wastewater treatment equipment.

Technical Advantages

Stable effluent

The system effectively adapts to fluctuations in influent water quality, efficiently removing pollutants, and ensuring stable and compliant effluent quality.
Low operating cost

Through refined control, the system reduces chemical usage and energy consumption.
High degree of automation

The system employs automated control, allowing for precise operation with lower technical requirements for personnel.
Short construction period

Factory prefabrication minimizes the impact of environmental factors, leading to shorter construction periods compared to traditional methods.

Applications

Petrochemical wastewater treatment
Fine chemical wastewater treatment
Basic chemical wastewater treatment
Pharmaceutical chemical wastewater treatment
