example 1

[0038] Example 1: Treatment experiment of landfill leachate (including cleaning wastewater) produced by a waste compression transfer station in Guangzhou.

[0039] Biofilm cultivation: After closing the outlet pipe 20, continue to feed water until the whole device is filled with sewage, open the water inlet pipe 19, change to continuous water inlet, the flow rate is 2t / d-3t / d, and control pouring into the T-shaped AF reaction tank 3 The dissolved oxygen value is less than 0.2mg / L, the dissolved oxygen value of the first-level anoxic zone, the second-level anoxic zone, and the third-level anoxic zone is greater than 0.5mg / L, and the first-level aerobic zone, the second-level aerobic zone, and the third-level The dissolved oxygen DO value in the level aerobic zone is greater than 2mg / L. Three days after the leachate enters the water, the sewage flow rate is increased to 6t / d-8t / d. Seven days after the water enters, it is found that the filler is basically covered with biofilm , ...

example 2

[0043] Example 2: Treatment experiment of landfill leachate (including cleaning wastewater) at a transfer station in a village in Shenzhen.

[0044] The waste treatment station has a relatively small amount of treated water, with an average daily treated water amount of about 6.5t / d, and a relatively low COD concentration. In order to reduce energy consumption and maintain the activity of activated sludge, the medium load mode is selected for treatment. The baffle plate 9 appropriately reduces the reaction volume of the A / O reaction tank 23 to 2 / 3 of the full load volume, reduces the primary A / O reaction system, and uses the secondary A / O reaction system to treat the leachate of the transfer station.

[0045] Similar to Example 1, after about a week of biofilm cultivation, the landfill leachate that was gradually connected to the transfer station was processed. Since the water volume was relatively small, a certain amount of leachate was accumulated in the water quality adjustm...

example 3

[0046] Example 3: Treatment experiment of leachate (including cleaning wastewater) at the garbage transfer station in Tianxin District, Changsha City, Hunan Province.

[0047] The vicinity of the garbage transfer station in Tianxin District, Changsha City is mainly residential areas and commercial office areas. The output of landfill leachate has obvious fluctuations in different time periods. During the peak period of filtrate production, the output of landfill leachate at the transfer station can often reach 12t / d, and at night, during the low valley period, the leachate output is as low as 6-8t / d, so three-stage landfill is used during the peak period of leachate transfer. For A / O full-load processing, during the night time, the processing load of the processing device is appropriately reduced, and the medium-load processing mode is adopted: the secondary A / O reaction pool 23, the processing volume is 2 / 3 of the full-load volume, and after online monitoring, The COD concent...

Abstract

The invention discloses an adjustable integrated garbage transfer station leachate treatment system and process, including a protective shell, the inner cavity of the protective shell is sequentially provided with an inverted T-shaped AF reaction pool, a water quality adjustment pool and an A / O reaction tank, the right side of the water quality adjustment tank is connected with a water inlet pipe, and the right side of the inverted T-type AF reaction tank inner wall is equipped with a blower fan, and one end of the blower fan communicates with the bottom of the ring-shaped aerobic tank , the A / O reaction pool is a four-layer ring design. The present invention simplifies the traditional A / O process of multiple pools connected in series by taking the inverted T-type AF reaction pool and the three-stage A / O reaction pool technology as the core, and controls the A / O reaction pool through the setting of the electronically controlled baffle 9 The number of stages and sizes, and the three-dimensional design of the inverted T-shaped AF reaction pool, water quality adjustment pool and A / O reaction pool from bottom to top reduces the volume of the device. This design connects the independent pools in series in a three-dimensional cylinder In the equipment, the occupied area is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an adjustable integrated garbage transfer station leachate treatment system and process. Background technique [0002] With the rapid development of urbanization in our country, people's quality of life is constantly improving, and the output of domestic waste is also increasing year by year. Domestic waste treatment has become an urgent problem in the process of urbanization. The garbage transfer station is an important part of the domestic waste removal system. Partly, its leachate treatment has always been a very difficult problem in the operation and management of the transfer station. The survey shows that the leachate of the garbage transfer station is mainly composed of domestic sewage, flushing wastewater, and sewage generated during the garbage compression process. The output of leachate is from From 7t / d to 15t / d, it is characterized by small output, high conc...
