Description
Technical field
The utility model is related to advanced treatment of wastewater field, more particularly to a kind of for sewage treatment plant tail water advanced treating
Artificial wet land system.
Background technology
The form of export of China's municipal wastewater treatment plant tail water up to standard is mainly to concentrate discharge, and utilizes the self-purification capacity pair in river
Pollutant in tail water is further degraded, to meet the water environmental function target of receiving water body.But with urbanization process
Accelerate so that most tail water produced by municipal sewage treatment plant is received river and gradually loses water environmental function.To reach higher discharge mark
Standard, many water factories are due to design reasons, and original processing unit can not meet in existing requirement, field upgrading due to place
With the limitation of former technique, it is difficult to carry out upgrading, therefore increasing sewage treatment plant tail water depth in tale quale
Science and engineering journey has carried out planning construction.Due to using maturation process municipal sewage plant, its organic matter removal ability is stronger, goes out more
COD, BOD concentration are low in water, and relative surface water environment quality, its water outlet nitrogen, phosphorus concentration it is higher, as in advanced treating
Emphasis.
Technology in terms of existing artificial swamp is used for sewage treatment plant tail water advanced treating is more from wetland structure, leads to
The combination of different type wetland is crossed, contaminant removal efficiency is improved, but still there is artificial marsh sewage treatment system processing effect
Rate is low, and the carbon source of sewage treatment plant tail water is not enough, causes the low problem of nitric efficiency.
Utility model content
It is low that the utility model overcomes artificial marsh sewage treatment system treatment effeciency of the prior art, sewage treatment plant
The carbon source of tail water is not enough, and causing the low shortcoming of nitric efficiency, there is provided a kind of people for sewage treatment plant tail water advanced treating
Work wet land system.
