Embodiment
Be that the present invention is further described below in conjunction with accompanying drawing.
Equipment described in the utility model, be made up of reaction zone at the bottom of tower 1, aerobic nitrification district, middle part 2, top three-phase separation area 3, total blade diameter length ratio is between 1:6 to 1:15, and at the bottom of tower, reaction zone 1, aerobic nitrification district, middle part 2, top three-phase separation area 3 volume ratio maintain 1:3:1.Division board is provided with between reaction zone and aerobic nitrification district, reaction zone at the bottom of tower comprises and to be connected with division board and to pass the muddy water circulation upcast that division board stretches to interior tower, muddy water circulation upcast lower end is provided with the hole passed through for sewage, the aerator be connected with air pump is provided with in muddy water circulation upcast, be denitrification zone 4 between outer tower and muddy water circulation upcast, aerobic nitrification district, middle part is provided with inner tower and outside tower, Nei Ta lower end is provided with muddy water circulation seam, the triphase separator of falling funnel shaped is provided with in three-phase separation area, three-phase separation area top is provided with effluent weir, effluent trough is provided with around tower top, effluent trough is provided with water outlet, Nei Ta upper end extends in three-way separator, on interior tower, head tower wall is provided with space, reaction zone connects sewage water inlet pipe, nitrification liquid return line is provided with between reaction zone at the bottom of top three-phase separation area and tower, mud return line is provided with between aerobic nitrification district, middle part and reaction zone, lower end, aerobic nitrification district, middle part is provided with mud discharging pipe.
Treatment sewage enters reaction zone at the bottom of tower by water inlet pipe 15, and the mud refluxed with mud return line 14 contacts, and mud is screened and preculture.The nitrification liquid that nitrification liquid return line 13 refluxes contacts with mud with former water, under anoxic condition, carry out anti-nitration reaction.Aerator 6 continues aeration, and make the gas speed that rises in the interior tower 9 in aerobic nitrification district 2, middle part maintain between 5-15m/h, then in the middle part of it, aerobic nitrification district dissolved oxygen can maintain more than 2.0mg/L.Under the drive of upstream, the sewage in reaction zone 1 at the bottom of tower and mud to rise in aerobic nitrification district 2, middle part in tower 9 by muddy water circulation upcast 5, then carry out sewage by triphase separator 10, mud is separated with gas.The result be separated is that sewage flows downward in interior tower 9 with space in outer tower 8, mud precipitates bottom space between inside and outside tower, part returns interior tower 9 and outer tower 8 intermediate gaps with water, and then be back to aerobic nitrification district, middle part, gas is discharged by triphase separator 10 top vent pipe, and three-phase separation area top sets out mill weir, and the process water after precipitation is flowed out by tower top effluent weir, collected by water leg 12 again, discharge from water outlet 11.
Connect nitrification liquid return line 13 in the above region of sludge blanket, triphase separator 10 top, be back near water inlet pipe 15, for denitrification provides nitric nitrogen nitrogenous source, improve denitrification effect.Bottom aerobic nitrification district, middle part 2, connect mud return line 14, near sludge reflux to water inlet pipe 15, realize mud and contact mix with water inlet, so the microorganism being suitable for this kind of waste water in screening mud, the efficiency of raising sludge degradation dirt organic pollutants.Nitrification liquid backflow and sludge reflux can, by the pressure difference at the bottom of reaction zone 1 at the bottom of tower and aerobic nitrification district, middle part 2 and tower between top, reaction zone 1 three-phase separation area 3, realize from main flow, without the need to separately adding power wheel drive.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from structure or the notebook scope as defined in the claims of utility model, protection domain of the present utility model is all belonged to.
