The air supply device of the wastewater treatment station further comprises a first gate valve 7 arranged in the first air supply pipeline 5 or the second air supply pipeline 6. In some embodiments, a first gate valve 7 is provided in the first blast line 5.
The flow area of the first air supply duct 5 is smaller than the flow area of the second air supply duct 6.
The air supply device comprises two fans 1 and a flow collecting pipeline 4, the two fans 1 are respectively communicated with the flow collecting pipeline 4 through connecting pipelines, and a first air supply pipeline 5 and a second air supply pipeline 6 are respectively communicated with the flow collecting pipeline 4. One of the two fans 1 is a standby fan, and the other fan works normally. In some embodiments, the two operate alternately.
The air supply arrangement of the wastewater treatment station also comprises a second gate valve 3 arranged in the connecting line.
The air supply arrangement of the wastewater treatment station also comprises a non-return valve 2 arranged in the connecting line. The check valve 2 is located upstream of the second gate valve 3 in the flow direction of the air output by the fan 1.
The fan 1 comprises an air suspension fan.
In the embodiment, 2 15KW air suspension fans (1 is used for 1) are adopted to replace 3 aeration fans, and the air volume provided by a single 15KW air suspension fan during full-power operation is 15m3Min, can simultaneously meet the maximum air quantity of 2.8m of the biochemical pool3Min and maximum air volume of regulating tank of 13.82m3The requirement of/min, and the wind pressure that single 15KW fan provided is 0.8bar, also satisfies biochemical pond and the requirement of 0.6bar of the biggest wind pressure of equalizing basin (see table 2). However, there is no related "one-for-two" connection device to supply the surplus air on the biochemical pool pipeline to the regulating pool.
In order to cancel a 7.5KW Roots aeration fan which independently supplies air to a regulating reservoir, and supply redundant air quantity on a biochemical reservoir pipeline to the regulating reservoir for use, and reduce the annual power consumption of a fan set, an opening is formed by the way of leading to the biochemical reservoir pipeline after 2 15KW aeration fan outlets are converged to the same pipeline, the opening is butted with the pipeline leading to the regulating reservoir by the original 7.5KW pre-aeration Roots fan, meanwhile, a gate valve with a certain opening degree is added to the pipeline leading to the regulating reservoir, so that the situation that the air supply of the biochemical reservoir is insufficient due to the fact that the air in the biochemical reservoir pipeline intensively runs to the regulating reservoir with smaller pressure is prevented, the purpose that one fan 1 simultaneously supplies air to the biochemical reservoir and the regulating reservoir is achieved, and the effects of saving energy and reducing consumption are achieved.
According to the invention, an opening is formed in the back side of the outlet of 2 15KW biochemical pool aeration fans which are converged to the same pipeline, and the outlet is butted with an adjusting pool pipeline through pipeline welding (the aperture of the adjusting pool is 65A; the aperture of the biochemical pool pipeline is 125A), and meanwhile, a gate valve capable of manually adjusting the opening degree is additionally arranged on the pipeline of the adjusting pool, so that the excessive air quantity is supplied to the adjusting pool for use while the normal air supply of the biochemical pool is ensured, the purpose of simultaneously supplying air to the biochemical pool and the adjusting pool by one biochemical pool aeration fan is realized, and the consumption reduction of a fan set is reduced.
The air supply pipeline of 2 15KW biochemical pool aeration fans and the air supply pipeline of a regulating pool of a waste water treatment station in a power workshop are correspondingly connected and transformed according to the method. And according to the gate valve which can be manually adjusted and installed on the pipeline of the regulating reservoir, the opening degree of the gate valve is set to be 75%, so that the requirement that the regulating reservoir is 2.8m when the liquid level is 5m is met3The air quantity requirement of/min also guarantees the normal air supply of the biochemical pool, achieves the effect that the aeration fan of the biochemical pool supplies air to the biochemical pool and the regulating pool simultaneously, and achieves the purposes of energy conservation and consumption reduction.
