Described Er Chen district is provided with inclined plate packing, anaerobism settling region guiding device and overflow weir, the sewage Jing Erchen district guiding device water conservancy diversion that enters Er Chen district enters inclined plate packing process after overflow weir overflow by being positioned at top, Er Chen district to clear water zone, by pipeline from flowing to artificial wet land system.
In described clear water zone, be provided with blower fan under liquid, for bio-contact oxidation district blast aeration He Erchen district automatic backflow apparatus required drive is provided.
Described artificial wet land system is provided with water distribution system and artificial swamp training wall, and described water distribution system is undercurrent drop formula, supernatant liquor after water distribution system water distribution uniformity after the water outlet of artificial swamp training wall water conservancy diversion qualified discharge.
Due in the water outlet in bio-contact oxidation district with a small amount of microbial film and excess sludge, precipitate postprecipitation in second pond through second pond, mud in second pond adopts automatic backflow apparatus, the backflow of backflow biological sludge enters anaerobism settling region and carries out nitrification and denitrification biochemical treatment, carry out sanitary sewage ammonia nitrogen minimizing processing, when water inlet, in sewage, nitrogen is mainly to exist with ammonia nitrogen form, after providing dioxygen oxidation by aerating system, bio-contact oxidation district is transformed into nitric nitrogen, after entering anaerobism settling tank, automatic backflow apparatus carries out denitrification, nitric nitrogen is transformed into nitrogen, thereby reach the object of removing a part of ammonia nitrogen.
The present invention by sewage treatment unit integrated combination form integrated apparatus, reasonable arrangement the position relationship of each integral part, anti impulsion load ability is strong, organic matter removal efficiency is high, save floor space 20%～30%, reduce cost of investment 20%～30%, convenient management, operational efficiency are high.
In treatment unit of the present invention, increase mud automatic back flow, enter front end anaerobism settling region and carry out 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.
