Sewage Treatment System
Product Features
1. Overview
At present, the design and implementation of sewage treatment plant automation system in China is in a growing period, and there are still imperfections in the demand, design, structure and control of the system. The integrated sewage automation system scheme provides services for the construction, operation and management units of the sewage treatment plant. It not only ensures the stability and efficiency of the production of the sewage plant, reduces labor intensity, improves the operating environment, but also improves the modern production management level of the sewage plant. The comprehensive automation system solution integrates the concept of building a modern sewage treatment plant into the design of the automatic control system on the basis of fully considering the characteristics of the sewage treatment process.
2. Composition of automatic control system
The automatic control system of sewage treatment plant is composed of field instruments and actuators, signal acquisition control and human-machine interface (monitoring) equipment. The construction of automatic control system mainly refers to the selection of three parts of system form and equipment. The actuator is mainly determined by the process discipline according to the requirements of the process, 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. Man machine interface mainly refers to the selection of monitoring equipment in the central control room and on-site duty room.
3. Process flow and system realization function
The sewage treatment process is divided into three levels: first level treatment: physical treatment, through mechanical treatment, such as grille, sedimentation or air flotation, to remove stones, sand, fat, grease, etc. contained in the sewage. Secondary treatment: biochemical treatment, in which pollutants in sewage are degraded and transformed into sludge under the action of microorganisms. Tertiary treatment: advanced treatment of sewage, which includes the removal of nutrients and disinfection of sewage through chlorination, UV radiation or ozone technology. Depending on the treatment objectives and water quality, some sewage treatment processes do not include all the above processes.
Main functions: this control system combines automatic control technology with intelligent monitoring and management technology, is developed based on the process control idea of sewage treatment plant, and is based on the premise of ensuring the stable operation of sewage treatment plant to achieve energy conservation and consumption reduction to the greatest extent.

Gantry cutting system
With the progress of China's economic level and scientific and technological level, gantry shears, as a manifestation of mechanical equipment, have been widely used in today's society, not only because this type of shears have very good functions, but also because the production technology of shears has been improved to a certain extent. Gantry shears cut the messy recycled waste into unified materials that are easy to regenerate, which increases the sales channel of materials. The gantry shear consists of two parts, the mechanical part and the hydraulic part of the machine. These two parts cooperate with each other to complete the daily material cutting work.
