Urban sewage treatment oxidation ditch training device

Urban sewage treatment oxidation ditch tr--ning device,Temperature PID simulation control tr--ning device

1. Scope and principle of application:

When the oxidation groove is used to treat urban sewage, the first sedimentation tank may not be provided. The suspended organic matter can be oxygen and stable in the oxidation groove. This is more economical than setting up a sludge stability system for setting up a sedimentation tank and a separate device. However, in order to prevent the accumulation of inorganic sediment in the oxidation groove, the original sewage should be pre -processed by the grille and the sand pool. Oxidation sulcus structure and process process. This device is a teaching experimental equipment for oxidation grooves. Through the hope of this experiment, the following goals are achieved:

1. Master the internal structure of the oxide groove;

2. Understand the hydraulic characteristics, hydraulic flow and process characteristics of oxidation grooves.

Urban sewage treatment oxidation ditch tr--ning device,Temperature PID simulation control tr--ning device

Features:

PID temperature control tr--ning model is a typical control object.

It is equipped with a thermal room made of high -temperature glass, and the 24V DC power supply is a heating circuit and a temperature detection circuit for the power supply. The heating power is controlled by the DC signal of 0-10V, and the temperature signal is indicated by the DC signal output of the one 0-10V. The device of the transparent structure is intuitive, making the tr--ner easy to accept. Two DC voltage meters of 0-10V are provided to monitor the input signal and temperature signal of the heating circuit and temperature detection.

The analog input, output tr--ning and PID closed -loop control tr--ning can be performed by the programmable controller.
