A separating folded plate is arranged at the top of the advanced oxidation reactor and divides the advanced oxidation reactor into a first reaction area and a second reaction area, a water inlet is formed in the top of the first reaction area, a water outlet is formed in the top of the second reaction area, annular perforated aerator pipes are arranged at the bottoms of the first reaction area and the second reaction area respectively, a baffle with meshes is arranged at the bottom of the first reaction area, a filler area is arranged on the baffle with the meshes, and the filler area is filled with particle filler. The energy-saving efficient integrated wastewater treatment device is compact in structure, small in occupied area and high in treatment efficiency; waste water is subjected to decoloring and COD reduction treatment with an advanced oxidation method, and it is guaranteed that the treated wastewater meets the requirements of the national-level A standard.

Description

Technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an energy-saving and highly efficient integrated wastewater treatment device. Background technique [0002] In the past 20 years, with the rapid development of China's economy, especially the rapid advancement of urbanization, the types and quantities of synthetic organic matter have increased day by day, causing a large number of complex and difficult-to-degrade organic pollutants to enter water bodies, which are easily bio-enriched through the food chain. Organisms produce a series of hazards such as carcinogenic, teratogenic, and mutagenic. For this reason, with the promulgation of the new environmental protection law and the introduction of the "Ten Water Regulations", the requirements for pollutant discharge standards are becoming more and more stringent. The effluent from sensitive areas should meet the "Urban Wastewater Treatment Plant Pollutant Discharge Standard"...

Problems solved by technology

For example, the Chinese patent (publication number CN102180558A) discloses a composite advanced oxidation treatment process, the electrochemical reaction zone is mainly micro-electrolysis reaction, Fe 2+ Produce OH directly with the ozone reactor, the reaction rate is far lower than the Fenton reaction system; Chinese patent (publication number CN101955280A) discloses a composite electrochemical treatment process, which electrocatalyzes the production of H 2 o 2 Fe production by reaction and microelectrolysis 2+ The reactions are in different reactors, and the synergistic effect of the electro-Fenton reaction is not good; Chinese patent (publication number CN201510160332) discloses an advanced oxidation coupling device and process for the treatment of degraded organic wastewater, which couples electrocatalytic oxidation, Ozone oxidation, Fenton oxidation and micro-electrolysis treatment four technologies, the device structure is complex, the production process is cumbersome, and the cost is high

[0006] Although the above-mentioned advanced oxidation combination device can improve the treatment efficiency of refractory organic wastewater to a certain extent, there are still problems such as ineffectiveness and lack of flexibility, which limit industrial promotion and application
