Problems solved by technology

Its disadvantages are: the combination of multiple technologies leads to a long treatment process, complicated operation procedures, increased control difficulty, and is easily affected by changes in external conditions.
[0009] Due to the high content of suspended solids in complex organic wastewater, if it stays in the pipeline for a long time, it is easy to adhere to the stagnant water area of ​​the reactor. As time goes on, it will block the pipeline, increase the resistance of the pipeline, reduce the flow capacity, and cause the inlet pump Cannot work normally, affecting the efficiency of wastewater treatment

Embodiment Construction

[0077] The present invention will be described in further detail in conjunction with accompanying drawing:

[0078] figure 1 The process flow of the microwave-assisted Fenton rapid oxidation organic wastewater treatment method of the present invention is shown.

[0079] Treat the complex organic wastewater accepted by a hazardous waste treatment company. The raw water quality: COD 4000-10000mg / L, suspended solids concentration 1000mg / L, pH 6-7.

[0080] see figure 1 As shown, including: complex organic wastewater - filtration - pH adjustment - Fenton reaction - microwave - alkali neutralization - coagulation - precipitation - supernatant, the specific treatment process is as follows:

[0081] (1) Start the automatic control system, and the complex organic wastewater to be treated in the wastewater storage tank is transported to the Fenton reactor water inlet pipe through the fluorine-lined plastic high-pressure magnetic pump. The head of the magnetic pump is 25m, and the flo...

Abstract

The invention relates to a method for fast oxidizing complicated organic wastewater through microwave assisted Fenton, and a microwave assisted Fenton fast treatment reactor. The complicated organic wastewater is used as a treatment object; organic matters are degraded under the conditions of normal temperature and normal pressure. When the method is used, under the condition of not influencing the organic matter removal rate, the treatment time can be shortened to 15min. The method has the advantages that the goal of fast oxidizing organic matters by microwave assisted Fenton is realized; through the functions such as selective heating, low-temperature catalysis and fast penetration of microwave fields on microwave absorption matters, the degradation and the flocculation of the organic matters are promoted; the Fenton reaction time can be greatly shortened; the operation is simple and convenient; the automatic control can be realized; the method belongs to an efficient and energy-saving difficult-to-biodegrade organic wastewater treatment method.

Description

technical field [0001] The invention relates to a microwave-assisted Fenton rapid treatment method for complex organic wastewater, a microwave-assisted Fenton rapid treatment reactor, a control method for a microwave-assisted Fenton rapid treatment reactor, and equipment flushing control for a microwave-assisted Fenton rapid treatment reactor method. Background technique [0002] Hazardous waste disposal enterprises are the main source of complex organic wastewater. Due to the nature of their operations, the collected wastewater and liquid waste come from various industries and enterprises in the region. Not only are the types and pollution conditions of hazardous waste produced by different production enterprises different, There are also great differences in the types and pollution conditions of hazardous waste generated in the production process. Due to the limitations of existing classification rules and poor implementation of classification measures, the waste water col...
