Embodiment 1

[0029] (1) Preparation of filler: a. The main component of the inert biological filler for the aerobic chamber is humified garbage with a particle size of less than 20mm that has been closed for more than 8 years in the domestic waste landfill. When preparing the filler, firstly, the waste should be excavated in the landfill that has been closed for a sufficient time, and then the humic waste with the required particle size should be obtained by using a drum sieve with an aperture of 20mm. b. The filler used in the anaerobic chamber is fine coal, and the coal used is anthracite or lignite. During preparation, a 10mm drum sieve is used to obtain fine coal with required particle size.

[0030] (2) Construct the reactor: such as figure 2 As shown, the reactor mainly includes a shell, an air duct 10, an anaerobic chamber 1, an aerobic chamber 11, a water collection chamber 6, and a water inlet pipe 7. The top of the shell is provided with a water inlet pipe 7, and the bottom of ...

Embodiment 2

[0037] (1) Preparation of filler: a. The main component of the inert biological filler for the aerobic chamber is humified garbage with a particle size of less than 20mm that has been closed for more than 8 years in the domestic waste landfill. When preparing the filler, firstly, the waste should be excavated in the landfill that has been closed for a sufficient time, and then the humic waste with the required particle size should be obtained by using a drum sieve with an aperture of 20mm. b. The filler used in the anaerobic chamber is fine coal, and the coal used is anthracite or lignite. During preparation, a 10mm drum sieve is used to obtain fine coal with required particle size.

[0038] (2) Construct the reactor: such as figure 2 As shown, use glass fiber reinforced plastics or steel or reinforced concrete to build a semi-sealed shell structure. The reactor shell can be designed as a circle or a square, and the diameter or side length can be determined according to the ...

Embodiment 3

[0044] (1) Preparation of filler: a. The main component of the inert biological filler for the aerobic chamber is humified garbage with a particle size of less than 20mm that has been closed for more than 8 years in the domestic waste landfill. When preparing the filler, firstly, the waste should be excavated in the landfill that has been closed for a sufficient time, and then the humic waste with the required particle size should be obtained by using a drum sieve with an aperture of 20mm. b. The filler used in the anaerobic chamber is fine coal, and the coal used is anthracite or lignite. During preparation, a 10mm drum sieve is used to obtain fine coal with required particle size.

[0045] (2) Construct the reactor: such as figure 2 As shown, use glass fiber reinforced plastics or steel or reinforced concrete to build a semi-sealed shell structure. The reactor shell can be designed as a circle or a square, and the diameter or side length can be determined according to the ...

Abstract

The invention provides a distributed domestic sewage treatment reactor and a treatment method thereof; wherein, the reactor mainly comprises an outer shell, a gas-guide tube, an anaerobic chamber, an aerobic chamber, a catchment chamber and a water inlet tube; the bottom is provided with a water outlet, and the anaerobic chamber, the aerobic chamber and the catchment chamber are arranged from top to bottom, wherein the shell belonging to the aerobic chamber is provided with air inlet holes, filler in the anaerobic chamber is anthracite or lignite with a grain diameter less than 10mm, the filler in the aerobic chamber is humification rubbish which goes through more than 8 years of closure of domestic sewage landfill with a grain diameter less than 20mm, the gas-guide tube is arranged on the symmetrical centerline of the reactor. The water outlet is connected with a water seal well, a circumfluence tube is arranged between the water seal well and the water inlet tube. The sewage treatment method has the following steps: treating a septic tank; carrying out anaerobic reaction, facilitating the sewage resulting from the anaerobic reaction to enter the underneath aerobic chamber to be subjected to aerobic reaction; finally, refluxing the effluent according to the proportion of 10-30%. The reactor and the method of the invention can effectively eliminate COD, NH3-N, TN and TP and realize discharge after reaching standards.

Description

1. Technical field [0001] The invention relates to a distributed domestic sewage treatment reactor and its treatment method, specifically an integrated biochemical reactor, which can be used for the treatment of distributed domestic sewage in rural areas and communities, and can also be used in hotels, Treatment of domestic sewage in expressway service areas, ships and other places. 2. Background technology [0002] In recent years, with the rapid development of my country's economy, a large amount of domestic sewage has been discharged, especially in rural areas of China, domestic sewage has rarely been comprehensively treated. Take the Taihu Lake region as an example. The economy of the Taihu Lake Basin is developed and the population is dense. In recent years, the discharge of domestic sewage along the lake has increased rapidly. Under the situation of large-scale promotion of industrial pollution source treatment "upgrading and upgrading" and the construction of urban s...
