Application and effect evaluation of sludge machine in industrial wastewater treatment

Wastewater produced in the process of industrial production often contains a large number of pollutants, and if it is directly discharged, it will cause great harm to the environment. Therefore, adopting efficient wastewater treatment technology is a key step to protect the environment and achieve sustainable development. In recent years, sludge machine, as an advanced wastewater treatment equipment, has shown excellent performance in industrial wastewater treatment.

1. Working principle and types of sludge machine

Sludge machine mainly separates solid particles in wastewater from water by physical and chemical methods. Common types of sludge machines include belt filter presses, centrifuges and screw presses. These machines use pressure or centrifugal force to force water through the filter cloth while leaving the heavier solids on the cloth, thus achieving solid-liquid separation.

2. Application of sludge machine in industrial wastewater treatment

Sludge machine is widely used in many industries such as chemical, pharmaceutical, food processing and so on. In the chemical industry, sludge machine can effectively remove suspended solids and some dissolved solids in wastewater, reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD). In the food processing industry, organic substances and oil and grease in wastewater can be removed through the treatment of sludge machine, which significantly improves the efficiency of wastewater treatment.

3. Evaluation of the effectiveness of the sludge machine

The evaluation of the effectiveness of sludge machine is mainly based on its treatment efficiency, operation cost and maintenance convenience in actual operation. Data show that the sludge machine can reduce the suspended solids content of wastewater by more than 80%, and the COD and BOD removal rate can reach 60% to 90%. In addition, the operating cost of the sludge machine is relatively low, as it consumes less energy and is easy to maintain, making it suitable for long hours of continuous operation.

4. Continuous optimization and future prospects

Despite the excellent performance of sludge machines in industrial wastewater treatment, there is still room for further optimisation. Future R&D may focus on improving treatment efficiency, reducing energy consumption and expanding the treatment range. At the same time, combining intelligent technologies, such as Internet of Things (IoT) technology for equipment monitoring and data analysis, will further enhance the operating efficiency and treatment effect of sludge machines.

Through continuous technological innovation and management optimisation, the sludge machine will be more widely used in industrial wastewater treatment, making greater contributions to the harmonious development of industrial production and environmental protection.
