The height of gravel is 30cm.
The filler that underflow type artificial wet land bottom is used is sandstone filler, includes fine sand, rough sand, gravel and calcite.
Wherein sand, gravel and calcite need to select one time through the husky mesh screen of sieve before level is matched somebody with somebody, to go the removal of impurity, whole sandstone packing layer
Height is 80cm, and the water plant of some classes of reed one or well developed root system has been planted in packing layer.
The rural sewage integrated treatment device of the decentralized of the present invention is made into one with method with reference to specific embodiment
Walk explanation.
Embodiment：
It is used to handle rural sewage disposal using the rural sewage integrated treatment device of the decentralized of the embodiment of the present invention, it is handled
Sewage quality it is as follows：COD=100~400mg/L, NH4 +- N=15~75mg/L, TP=3~6mg/L, pH=6.5~8.5.Rural area
The sanitary sewage of generation through apparatus main body outside filtering grid tentatively remove floating object and larger suspension among sewage, and
It is promoted to the water inlet of integrated apparatus main body by submersible sewage pump, then through apparatus main body reclaimed water solution regulatory region, contact-oxidation pool, flat
After the PROCESS FOR TREATMENTs such as flow settling pond, water leg, cloth tank, artificial swamp and disinfection of effluent, effluent quality is as follows：COD=18~
25mg/L, NH4 +- N=2.8~3.2mg/L, TP=0.42~0.48mg/L, reach《Urban wastewater treatment firm pollutant emission mark
It is accurate》One-level A standards.
Embodiment described above is only the preferably embodiment of the present invention, it should be pointed out that this hair
Bright protection domain is not limited thereto, and any those of ordinary skill in the art is in presently disclosed technology
Under basis, some changes and improvements made should be all included within the scope of the present invention.
