| titleOfInvention | NISS (No Inner circumference with Stepfeed System) phosphorus and nitrogen removal automatic control device and process |
| abstract | The invention discloses NISS (No Inner circumference with Stepfeed System) phosphorus and nitrogen removal automatic control device and process, belonging to the technical of deep biological phosphorus and nitrogen removal from sewage. A touch screen PLC (Programmable Logic Controller) automatic control cabinet of the device is connected with a water feed pump, an online COD (Chemical Oxygen Demand) analyzer and the like in the NISS phosphorus and nitrogen removal device, the feed water concentration and related parameters in the phosphorus and nitrogen removal system are effectively controller, and unmanned operation is realized in the treatment process. The carbon source in original water is utilized to the maximum extent by feeding water in two steps, so that the biological phosphorus and nitrogen removal of sewage can be realized without adding extra carbon sources, and the cost is reduced. Because online monitoring is adopted, the parameters of water feed quantity and the like can be automatically adjusted, so that the impact and load resistance of the entire system is improved. By automatically adjusting the current of a matched air blower for controlling the concentration of dissolved oxygen, the wastage of electrical energy under the condition of low water feed quantity is avoided, the operating cost of water plants is effectively lowered, and meanwhile, the effects of saving energy and reducing consumption are achieved. |
