Be provided with blower fan under the liquid in the described clear water zone, be used to provide blast aeration of bio-contact oxidation district and two heavy districts automatic reflux required drive.
Described artificial wet land system is provided with water distribution system and artificial swamp training wall, and described water distribution system is a undercurrent drop formula, supernatant liquor through the water distribution system water distribution uniformity after qualified discharge after the water outlet of artificial swamp training wall water conservancy diversion.
Owing to have a spot of microbial film and excess sludge in the water outlet in bio-contact oxidation district, be deposited in the second pond through the second pond post precipitation, mud in the second pond adopts automatic reflux, the backflow of backflow biological sludge enters the anaerobism settling region and carries out the nitrification and denitrification biochemical treatment, carrying out the minimizing of sanitary sewage ammonia nitrogen handles, during water inlet in the sewage nitrogen mainly be to exist with the ammonia nitrogen form, after providing dioxygen oxidation by aerating system, the bio-contact oxidation district is transformed into nitric nitrogen, after reflux advances the anaerobism settling tank automatically, carry out denitrification, nitric nitrogen is transformed into nitrogen, thereby reaches the purpose of removing a part of ammonia nitrogen.
The present invention has rationally arranged the position relation of each integral part with the integrated integrated apparatus that is combined to form of sewage treatment unit, and the anti impulsion load ability is strong, organic matter removal efficient height, save floor space 20%～30%, reduce cost of investment 20%～30%, convenient management, operational efficiency height.
Increase mud in the treatment unit of the present invention and reflux automatically, enter front end anaerobism settling region and carry out the denitrification denitrogenation processing, improve nitric efficiency, nitric efficiency can reach more than 90%.
Sanitary sewage after treatment can reach " urban wastewater treatment firm pollutant emission standard " (GB8978-2002) one-level A standard.
