specific Embodiment approach 1

[0005] Specific implementation mode one: combine figure 1 Describe this embodiment, the semi-submerged sewage biological contact oxidation tank of this embodiment is divided into upper and lower parts by the non-submerged filler support layer 1, the upper part is the non-submerged filler layer 12, and the surface of the non-submerged filler 14 is attached with the volatile matter emitted by the sewage. Microorganisms cultivated and domesticated by odor-causing organic pollutants. The lower part includes submerged packing layer 2, aeration device 9, sewage water inlet device and treated water outlet device. Microbes cultivated and domesticated by sewage are attached to the surface of submerged packing 15; biological contact oxidation tank sewage The height of the water inlet and outlet devices is lower than the non-submerged packing support layer 1.

[0006] In this embodiment, the non-submerged filler supporting layer 1 and the upper non-submerged filler 14 completely cover th...

specific Embodiment approach 2

[0007] Specific embodiment two: The difference between this embodiment and specific embodiment one is: the non-submerged filler 14 is made of coke, activated carbon, ceramsite, anthracite, crushed stone, gravel, zeolite, perlite, peat, wood chips, shavings, bamboo chips , sand, slag, ceramic rings, plastic balls, crushed shells, textile fibers, and sponges; the thickness of the non-submerged filler is 0.5-1.2m. Others are the same as the first embodiment.

specific Embodiment approach 3

[0008] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the non-submerged filler 14 is composed of coke, activated carbon, ceramsite, anthracite, plastic balls, broken shells, cotton, sponge and textile fibers; the non-submerged filler The thickness is 0.6-1.1m. Others are the same as the first embodiment.

Abstract

The invention relates to a semi-flooded sewage water biocontact oxidation tank and the sewage water processing method thereof. And it is separated by a nonflooded filling bearing layer into two parts, where the surfaces of the nonflooded and flooded fillings are attached with different microbes, and the sewage water entering in the tank is lower than the nonflooded filling bearing layer. And its processing method: firstly preprocessing the sewage water, feeding the sewage water into it and finally collecting the processed water, where the microbes on the surfaces of the nonflooded fillings are cultivated and acclimated by volatile smell-causing organic pollutants in the sewage water and those on the sufaces of the flooded fillings are cultivated and acclimated by the sewage water, and in the sewage water processing course, the sewage water is lower than the nonflooded filling bearing layer. And its removal rate of the volatile smell-causing organic pollutions is up to 90%-99%.

Description

technical field [0001] The invention relates to a sewage treatment device and a sewage treatment method thereof. Background technique [0002] Some volatile odor-causing organic pollutants (including some low-molecular fatty acids, amines, ethers, halogenated hydrocarbons, and aliphatic, aromatic, heterocyclic nitrogen or sulfur compounds in the existing sewage aerobic biological treatment process ) escape from the sewage, these gaseous pollutants emit foul smell, pollute the atmosphere, damage the environment, and can enter the human body through breathing, eating, contacting, etc., causing damage to the respiratory system, circulatory system, digestive system, endocrine system and nervous system disease. The current sewage aerobic biological treatment facilities and methods cannot effectively remove the volatile odor-causing organic pollutants emitted in the sewage, resulting in volatile odor-causing organic pollutants polluting the atmosphere.
