Description
Technical field
This utility model is related to a kind of rotation sand setting equipment.
Background technology
Setting pot is in the ratio very little shared by the aspects such as the investment of sewage treatment plant, occupation of land, but municipal sewage treatment
Requisite pretreatment facility in factory, its major function are to remove the sand grains in sewage, reduce sand grains and plant equipment is caused
Excessive abrasion.Operation and the maintenance cost of waste water disposal facility can be reduced before setting pot is arranged on subsequent processing device.Sand grains
It is inorganic matters, it is impossible to removed with biological method, if cancelling setting pot, a large amount of sand grains will be into subsequent processing units, to dirt
The normal operation of water factory brings many hidden danger.In fact, water body sand grains particle diameter is more little more is just conducive to sewage treatment process
Often run.
At present, traditional setting pot has mainly have horizontal-flow grit chamber, aerated grit chamber, rotational flow grit chamber etc., and these tradition are heavy
Sand pond is mainly used in removing the sand grains that particle diameter in sewage is accounted in 35～55 μ ms of the total sand grains of water body 80%, with protective conduit,
The facilities such as valve are from abrasion and block.Its operation principle is that, based on Gravity Separation, water inlet flow velocity is relatively low so that than great
Inorganic particle sink, organic suspension granule flows away with current, but the sand grains compared with small particle cannot be processed.As people are to water
The requirement more and more higher of matter, can maximize the advantage for playing biological treatment, and in fact in theory without sand grains in sewage
Sewage sand grains thoroughly cannot be removed, therefore it is bigger to subsequent biological treatment process acts to process 25～35 μm of sand grains.However, traditional
To also not high more than 35 μm of sand grains treatment effeciencies, actual treatment efficiency is typically in the range of 15%～70%, and transports for setting pot
It is capable and unstable.Further, since water intake velocity is relatively low, Organic substance is separated with sand grains not thoroughly, so as to have impact on effluent quality.
The content of the invention
This utility model is directed to the deficiencies in the prior art and provides a kind of raising water intake velocity, increases sand grains and Organic substance
Separation efficiency while, improve treatment effeciency of the setting pot sand grains particle diameter between 25～35 μm, its treatment effeciency is up to
90%, reach a kind of rotation sand setting equipment of investment reduction and operating cost.
This utility model adopts the following technical scheme that realization：A kind of rotation sand setting equipment, including setting pot, the setting pot
