Embodiment Construction
[0012] combine figure 1 Embodiments of the present invention will be described in detail.
[0013] 1) Taking the actual domestic sewage as the treatment object, the sewage first flows in through (4) the water inlet pipe, at this time (5) the water inlet flowmeter detects the flow signal and transmits the signal to (12) PLC controller, (12) PLC control The device sends an instruction to turn on the (8) air pump, (2) the first-stage aerobic compartment and (3) the second-stage aerobic compartment are in the state of aerobic aeration, and the reaction of aerobic removal of organic matter and ammonia nitrogen occurs, and at the same time (9 ) The stripping reflux pipe starts to return the nitrifying liquid in (3) the second-stage aerobic compartment to (1) the anoxic compartment for denitrification and denitrification reaction. At the same time, due to the nitrification reaction, the pH value gradually decreases, ( 10) pH probe and (11) dissolved oxygen probe continuously transmi...

The invention discloses an inlet flow, pH and dissolved oxygen-based method for remotely controlling the treatment of wastewater in villages and towns online by using a cloud platform, and belongs tothe technical field of sewage treatment. The big data and the cloud computing are taken as the basis, decentralized treatment equipment for treating the wastewater in villages and towns is intelligently operated and maintained through a control system comprising an equipment end, a central control room and the cloud platform, and the biochemical reaction process is controlled for the first time bymonitoring the real-time online parameter such as pH and dissolved oxygen; in addition, the parameter such as the inlet flow, the aeration rate, the on-off state of the equipment, the temperature andthe water quality are monitored, and the normal operation of the equipment and the up-to-standard discharge of the effluent are guaranteed. The method can accurately monitor and control the biochemical reaction process, reduces the energy consumption, and solves the difficult problems that because the fluctuation of quantity of the wastewater in villages and towns is large and the wastewater is decentralized, the operation and the maintenance are difficult.
Description
technical field [0001] The invention relates to a method for realizing online remote control of village and town wastewater treatment through a cloud platform based on influent flow, pH and dissolved oxygen. intermittent water problem. Background technique [0002] Due to the small amount of water and scattered characteristics of rural sewage, it is not suitable to adopt the mode of laying pipe networks for collection and then centralized treatment. The single-household mode of on-site treatment has gradually become an acceptable method. Due to the water use habits of the villagers, the water volume fluctuates greatly during the day and almost no sewage is generated at night, which requires real-time control technology. In addition, the large number of villages and towns puts forward higher requirements for operation and maintenance, which requires remote control technology. [0003] During the aerobic process of biochemical treatment, due to the consumption of alkalinity b...
