specific Embodiment approach 1

[0010] Specific implementation mode one: combine figure 1 Describe the Fenton-like fluidized bed sewage treatment device in this embodiment, which is mainly composed of the first Fenton reactor 1, the second Fenton reactor 2, the lift pump 7, the first circulation pump 3 and the second circulation pump 9 ; The first Fenton reactor 1 is communicated with the second Fenton reactor 2 through a lift pump 7; the two ends of the first circulation pump 3 are communicated with the first Fenton reactor 1, and the two ends of the second circulation pump 9 are connected with the first Fenton reactor. The second Fenton reactor 2 communicates.

specific Embodiment approach 2

[0011] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the second Fenton reactor 2 is equipped with granular activated aluminum, wherein the diameter of the granular activated aluminum is 2-5 mm. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0012] Embodiment 3: This embodiment is different from Embodiment 1 in that the second Fenton reactor 2 is equipped with granular activated aluminum, wherein the diameter of the granular activated aluminum is 3 mm. Other steps and parameters are the same as those in Embodiment 1.

Abstract

The invention provides a Fenton-like-fluidized bed sewage treatment device and a sewage treatment method thereof, and relates to a water treatment device and a sewage treatment method thereof. The sewage treatment device and the sewage treatment method thereof solve the problems that the reaction conditions are harsh in the reaction for the degradation of organic sewage and a large amount of ferrous sludge is generated during the reaction process. The device comprises a first Fenton reactor (1), a second Fenton reactor (2), a lifting pump (7), a first circulating pump (3) and a second circulating pump (9). The method comprises the following steps: 1. the sewage is treated in the first Fenton reactor (1); 2. the effluent index is controlled; 3. the sewage is treated in the second Fenton reactor (2) and the pH value is adjusted; and 4. the effluent index and the concentration of ferrous ion in the solution are controlled. The water treatment device and the sewage treatment method thereof adopt the method of combing Fenton-like process and sediment crystallization process, the process is improved, and the activity of biological treatment is enhanced. The process is applicable for thetreatment of special organic wastewater which is high in concentration and hard to be biodegraded, can not be treated by conventional process or can not obtain good treatment effect when being treated by the conventional process.

Description

technical field [0001] The invention relates to a method for treating sewage by using a water treatment device. Background technique [0002] High-concentration biodegradable organic wastewater has become the biggest problem in polluting the environment. At present, in terms of advanced wastewater treatment technology, the Fenton-like method has the advantages of high efficiency, wide application range, and low operating cost, and has been widely used in this field. However, there are reaction conditions in the reaction of degrading organic waste water by the Fenton-like method. Harsh (must be carried out under acidic conditions), the disadvantage of a large amount of iron-containing sludge will be produced during the reaction. Contents of the invention [0003] The purpose of the present invention is to solve the problem of harsh reaction conditions in the existing reaction of degrading organic waste water, and a large amount of iron-containing sludge can be produced in ...
