Currently, the design and implementation of wastewater treatment blower for wastewater treatment plant automation system in China is in the growth period, and there are still some imperfections in the system requirements, design, structure and control. Wastewater integrated automation system program for the construction of sewage treatment plants, operation and management units to provide services. It not only ensures the stability of sewage plant production, reduces labor intensity, improves the operating environment, but also improves the modern production and management level of the sewage plant. This comprehensive automation system solution integrates the concept of building a modernized sewage treatment plant into the design of the automatic control system on the basis of giving full consideration to the characteristics of the sewage treatment process.
The sewage treatment equipment utilizes the sewage treatment blower to continuously inject air into the sewage, so that the water in the pool is in contact with the air for oxygen supply, and the liquid is stirred to accelerate the transfer of oxygen from the air to the liquid, preventing the sinking of suspended matter in the pool. Sewage treatment blower strengthens the contact between organic matter and dissolved oxygen in the pool, so that the organic matter in the sewage can be oxidized and decomposed. Accelerates the flow of oxygen from the air to the liquid, prevents the suspended matter in the sewage treatment equipment from contacting with microorganisms and dissolved oxygen, and oxidizes and decomposes the organic matter in the sewage. The sewage treatment blower for water treatment treats organic matter in the water with dissolved oxygen and strengthens the contact between organic matter and dissolved oxygen in the pool. When the organic matter used in water treatment is oxidized and decomposed, it is forced into the water by the aerator.
1. The composition of the sewage treatment blower control system
Wastewater treatment plant automatic control system consists of on-site instrumentation and actuators, signal acquisition control and human-machine interface (monitoring) equipment. The construction of the automatic control system mainly refers to the selection of the three parts of the system form and equipment. The actuators are mainly determined by the process specialties according to the process requirements, and the interface of the automatic control system is reserved. The selection of instruments will be described in the later part. The signal acquisition and control part mainly includes the selection of basic control system and the selection of control equipment and necessary communication network after the system is determined. The man-machine interface mainly refers to the selection of monitoring equipment for the central control room and the on-site duty room.
2. Sewage treatment blower process and system to achieve function
Sewage treatment process is divided into three levels: a level of treatment: physical treatment, through mechanical treatment, such as grating, sedimentation or air flotation, to remove stones, sand, fat, oil and grease. Contained in the sewage. Secondary treatment: biochemical treatment, pollutants in sewage are degraded and converted into sludge by microorganisms. Tertiary treatment: deep treatment of sewage, including nutrient removal and disinfection of sewage by chlorination, ultraviolet irradiation or ozone technology. Perhaps some wastewater treatment processes do not include all of the above processes, depending on treatment goals and water quality.
Improve water utilization and reduce water waste. As an important water treatment equipment, sewage blower can significantly improve the water treatment effect and provide people with healthy water resources.
