Problems solved by technology

[0005] Most of the detection instruments used in some sewage treatment plants are off-line instruments with poor accuracy and reliability. The monitoring method is also to measure after sampling, and then adjust the operating status of the equipment according to the measurement results.
Therefore, it is difficult to carry out fast and effective online real-time control, which often leads to unstable water quality

Embodiment Construction

[0016] The present invention will be described in detail below according to the accompanying drawings.

[0017] As shown in Figure 1, the sewage from the urban sewage pipe network enters the gate, and the garbage in the water is picked up by the grill machine and sent out by the screw conveyor, and then transported to the landfill by vehicles. Sewage flows into the sump, is pumped by the lifting pump to the outlet channel, flows out of the pump station through the backflow prevention gate, and is transported to the sewage treatment plant through the urban pipe network for treatment. Among them, the grid machine, conveyor, lifting pump, etc. are all driven by motors. During the operation of the grill machine at the pump station, the grill machine will be automatically started according to the water level difference between the front and rear of the grill machine and the screw conveyor will be electrically interlocked to clean up the garbage in the water. Another way of working...

Abstract

The invention discloses a sewage processing pump station automation system, mainly comprising the industrial control computer and the scene control system, in which the scene control system includes the influent control subsystem and the effluent control subsystem, and the influent and effluent control subsystems all comprising the liquid level sensor and the implementation body, and between the industrial control computer and the influent and effluent control subsystems, connecting through the scene bus, to realize the full process control automation from the sewage collection, treatment to emission; the invention uses the computer as a platform, simply, conveniently and effectively real-time monitoring the entire running process of the pump station. By the computer operation interface, the invention can intuitively process systematic detection and maintenance, and in addition, the system uses the distributed control technology which has centralized management and decentralized control, thus ensuring the system has high reliability.

Description

technical field [0001] The invention relates to a sewage treatment process and automation control technology, in particular to a sewage treatment pumping station automation system. Background technique [0002] The shortage of water resources is one of the basic national conditions of our country, and the per capita water resources in our country are only a quarter of the world's average level. Due to the relative lag in water pollution control, the number of polluted water bodies has increased year by year, which has exacerbated the shortage of water resources. Most of the sewage discharged from cities in our country is discharged into rivers, lakes and seas without effective treatment. More than 90% of urban waters in the country are polluted to varying degrees, and nearly 50% of key urban drinking water sources do not meet water intake standards. Most of the northern cities in my country are plagued by resource-based water shortages, while the water-rich areas in the so...
