Industrial wastewater treatment device

Abstract

The invention relates to an industrial wastewater treatment device, which comprises a wastewater treatment system and a control system for controlling the wastewater treatment system, wherein the control system comprises a data acquisition unit and a programmable logic control (PLC) unit; the data acquisition unit is arranged in the wastewater treatment system; the signal output end of the data acquisition unit is connected with the signal input end of the PLC unit; and an output signal of the PLC unit controls and connects the wastewater treatment system. The PLC unit controls the wastewater treatment system, workers are not required to monitor and manage the industrial wastewater treatment device in field, wastewater treatment automation is realized, the operation management of the sewage treatment is simple and convenient, and sewage treated by the industrial wastewater treatment device reaches a standard stably.

Description

technical field [0001] The invention relates to an industrial wastewater treatment device. Background technique [0002] At present, the synthetic ammonia industry occupies an important position in my country's national economy and even in the global economy. The synthetic ammonia industry mainly provides raw materials for the production of nitrogen fertilizer, that is, the nitrogen element in the synthetic ammonia is separated for the manufacture of nitrogen fertilizer, and then the remaining waste water is discharged. However, in the industrial production of synthetic ammonia, coal and natural gas are mainly used as raw materials to synthesize ammonia, so in the production of nitrogen fertilizer The waste water produced in the process contains a large amount of substances that pollute the natural environment. If the discharged waste water is only purified by the self-purification of rivers and lakes, with the extension of time and the limited removal capacity of the enviro...

Problems solved by technology

At present, the anoxic / aerobic (A / O) biochemical treatment process is generally used for the treatment of synthetic ammonia industrial wastewater for denitrification. Due to the high concentration of ammonia nitrogen in the wastewater, the low phosphorus concentration and C\N ratio, it is generally necessary to add carbon source, phosphorus and alkali, but in actual operation, the water quality fluctuates greatly, the load stability of the treatment system is poor, the control measures of nutrient addition are usually not coupled with the water quality in time, and the process of sludge discharge and aeration lacks effective measures. The control strategy, the drainage cannot be stably up to the standard, and the entire wastewater treatment process is completed by manual on-site supervision, and there are also large errors. The above reasons have caused problems such as complex operation and management of the entire wastewater treatment plant, unstable wastewater compliance, and high operating costs. Appear
