Problems solved by technology

[0005] 3. At present, domestic sewage treatment plants generally adopt processes such as oxidation ditch, SBR, A / A / O, and BAF. With the introduction of the "Water Ten Measures", most of them are facing the problem of standard upgrading and transformation. Due to the low discharge standards used in design And the short board limitation of the process itself, the upgrading of the standard puts forward higher requirements for the three-level intensive treatment section, such as the need to increase the dosage, increase the dosage of carbon sources and increase the installed capacity, etc.
[0006] 4. For newly-built sewage treatment plants, if the traditional sewage treatment process is adopted, in order to achieve higher denitrification and phosphorus removal efficiency and the degree of degradation of other pollutants, it is necessary to increase the reactor volume, strengthen pretreatment, strengthen advanced treatment, increase The installed capacity can only be achieved by increasing the dosage, which greatly increases the cost of sewage treatment and the difficulty of operation and maintenance of the water plant

Abstract

The present invention discloses an integrated IODS reactor. According to the integrated IODS reactor, an anoxic zone, an aerobic zone and a precipitation zone form a parallel three-gallery form arranged on one end of the reactor, a pre-denitration and selection zone and an anaerobic zone are arranged on the other end of the reactor, and all function zones are cleverly and compactly arranged inside an integrated structure. According to the present invention, sewage enters the reactor by using a segmented entering manner, one part of the sewage and reflux sludge enter the pre-denitration and selection zone so as to be subjected to a complete contact reaction, and then enter the anaerobic zone, the other part of the sewage directly enters the anaerobic zone, the anaerobic zone sewage enters the starting end of the anoxic zone through the through hole wall, a first circulation (denitrogenation circulation) is formed between the anoxic zone and the aerobic zone through the circulation power provided by an air plug flow zone, a second circulation (precipitation circulation) is formed between the aerobic zone and the precipitation zone through the circulation power provided by the air plug flow zone, and the treated effluent is discharged out of the reactor from the precipitation zone.

Description

technical field [0001] The invention relates to a sewage treatment reactor, in particular to an integrated IODS reactor and a corresponding sewage treatment method. Background technique [0002] 1. Total nitrogen (TN) and total phosphorus (TP) are the main indicators of the pollution degree of water bodies by nutrient substances. When the nitrogen and phosphorus substances in the water exceed the standard, it will cause algae and other plankton to multiply rapidly, the dissolved oxygen in the water body will decrease, and the water quality will be reduced. Deterioration, fish and other organisms die in large numbers. [0003] 2. In February 2015, the Standing Committee of the Political Bureau of the Central Committee deliberated and approved the "Water Pollution Prevention and Control Action Plan", referred to as "Water Ten Measures", and issued it on April 2. The "Water Ten Measures" put forward specific requirements for the prevention and control of industrial pollution a...
