The Research Of Biological Hydrogen-Water Treatment Production Demonstration Project Automated System

The biological hydrogen is very important to solute the energy crisis and the environmental pollution. Our country works out the organic waste water zymotechnics biological hydrogen technology by the tired of oxygen active sludge and the organic waste water as produces raw material. It is proved by the experiment in HIT. This research was discovered first in our country and foreign and realized the experimental scale non-fossilization mold mushroom spawn for a long time to continue producing the biological hydrogen technology. It also realized the experimental scale continue to produce the hydrogen for a long time. It was a domain significant breakthrough in biological hydrogen.It needs to control the temperature, the PH value, the current capacity and so on the multitudinous parameters and the massive monitoring points in the biological hydrogen process. So we uses PLC (programmable logical controller) control technology. However PLC is pure logic sequential control function as well as its the opacity in controlled process. It also has some flaw in certain domains. PLC could not reach effect in the biological hydrogen control especially. Therefore, this topic takes the new biological hydrogen control system design mentality which uses PLC works in the lower position control system and on the top position uses the king-view to carry on the configuration.After it introduced the zymotechnics biology hydrogen technology technical process which was instructed under the ethyl alcohol fermentation biological hydrogen theory, it also elaborated the biological hydrogen water treatment automatic control system structure drawing and the control plan. It has carried on the detailed introduction to the lowest level entire production control process. It is including the mix regulating reservoir automatic control return route, the biological system hydrogen reactor temperature, the PH value control loop, the tired of the oxygen reactor temperature, the PH value control loop, need oxygen response pond control loop, sedimentation pond control loop, the biological hydrogen examination return route and so on..It has carried on the detailed explanation on the PLC hardware Simens S7-300 module disposition .Then it introduced the PLC software STEP7 programming tool and the procedure flow chart, the trapezoidal chart. It also carried on some examples. At last it uses the king-view to manufacture the top position machine monitoring software of this control system. It is including each kind of real-time, history trend curve, the report form, the alarm system and so on.
