Description
Technical field
Present disclosure is related to sewage purification system and method.
Background technology
Sewage purification is that it is purified for the water quality requirement for making sewage reach a certain water body of draining or reuse
Process.Purified water after sewage purification system is handled can be used for multiple fields, such as industrial water, agricultural irrigation, aquatic products
Industry, medicinal water etc..
Sewage purification technology is logical at present produces in the sewage for being applied to need to largely focus on, because sewage disposal needs in itself
Substantial amounts of cost is expended, initial investment cost is high, and floor space is big.Therefore sewage purification is generally all using the side focused on
Formula, to reduce the high risk of initial investment cost.But for being inherently distributed more scattered source of sewage, to purify these
If sewage still by the way of focusing on, can produce more cost of transportation；But if more scattered dirt will be distributed
Water is handled using existing conventional sewage purification system or method on the spot, then the equipment cost of early stage is also higher；Especially
It is related to the processing of such as country sewage, country sewage is different from the city that density is high and concentrates, and it is generally more scattered, individually
It is square or even scarcely populated, focus on sewage and be not obviously inconsistent actual conditions, early stage, cost of transportation was higher, therefore country sewage is often
Treatment in situ is needed, if but in each need place installation sewage disposal device to be processed and being equipped with corresponding technical operation personnel
Actual conditions it are not inconsistent more then, the equipment investment cost of early stage is higher.
