Description

High-efficiency combined-building type raceway-shaped oxidation ditch
Technical field
The present invention relates to a kind of runway shape oxidation ditch, be the Carrousel oxidation ditch class, belong to water-treatment technology field, refer in particular to a kind of high-efficiency combined-building type raceway-shaped oxidation ditch of the high-efficient denitrification and dephosphorization that aerobic-anaerobic, precipitation, oxidation ditch, second pond, sludge water backflow can be integrated in one.
Background technology
Typical Carrousel oxidation ditch (being runway shape oxidation ditch), be in series by outer fissure and some two ditch type oxidation ditches, it is a kind of many ditches series system, water inlet is with after mud mixes, along flowing that water (flow) direction is done not stop in ditch, one end in the inherent pond of ditch is installed the inversed umbrella type vertical surface aerating machine, the oxygen-rich area in close aerator downstream and the oxygen-starved area of aerator upstream have been formed, every group of ditch installed one, can satisfy in the darker oxidation irrigation canals and ditches and make the mixed solution thorough mixing, and can keep higher mass-transfer efficiency, it is more shallow to have overcome small-sized oxidation ditch ditch depth, defectives such as mixed effect difference.But the deficiency that exists is:
1, ditch is provided with second pond, equalizing tank outward, and floor space is big, and equipment is not compact;
2, surface aerating machine quantity is few, the free long flow path of mixed solution in the ditch, and the flow velocity inequality that is caused by turbulent flow might cause sludgd deposition, influences operating performance;
3, be difficult to avoid the contradiction of oxygen supply and stirring, especially under the lighter situation of influent quality, for reaching the rotating speed that energy-saving effect must reduce surface aerating machine, this just will sharply weaken stirring capacity, cause serious precipitation, alluvial mud;
4, for big-and-middle volumetrical oxidation ditch, the depth of water should not surpass 3.5m, and the average dissolved oxygen of single ditch oxidation ditch should maintain about 2mg/l, otherwise should set up underwater propeller, and investment and cost can increase.
Summary of the invention
The present invention is intended to overcome the deficiency of runway shape oxidation ditch, and a kind of efficient (deoxidation, dephosphorization) combined-building type raceway-shaped oxidation ditch is provided, and makes preliminary sedimentation tank or second pond and runway shape oxidation ditch outer fissure, and two ditch type oxidation ditches are integrated in one, and reduce floor space, reduce cost of investment.Main innovation is between the circular arc linkage section of outer fissure and two ditch type oxidation ditches the circle to be set, and this circle as preliminary sedimentation tank or second pond, is allowed the tangent or shared portion wall of circle and outer fissure inwall, has reduced cost of investment; Simultaneously,, improve nitric efficiency, have opening on the shared furrow bank of adjacent two ditch type oxidation ditches in order further to prolong the residence time of current in two ditch type oxidation ditches.Specifically implement like this: high-efficiency combined-building type raceway-shaped oxidation ditch, be in series by outer fissure and some two ditch type oxidation ditches, it is characterized in that being equipped with the circle between the circular arc linkage section of outer fissure and two ditch type oxidation ditches, have opening on the shared furrow bank of adjacent two ditch type oxidation ditches, be equipped with respectively in the opening from a turning training wall with one with the relative dividing wall of two ditch type oxidation ditch circular arc linkage sections, described turning training wall and dividing wall are respectively and leave water stream channel between furrow bank.
This circle can be designed to preliminary sedimentation tank or second pond with it as required, because general municipal effluent is not established preliminary sedimentation tank, and as be set to preliminary sedimentation tank, then in addition second pond to be set again, so the circle is set to second pond the best, can save pipeline and floor space, integral device is compacter.Tangent or the shared portion wall of circle and outer fissure inwall, tangent with two ditch type oxidation ditch outer walls from or the shared portion wall.The quantity of two ditch shape oxidation ditches is more than 2 groups, can be generally the 2-4 group according to design requirements decision group number.The circle is arranged to share semicircle wall, the cost of then can reducing investment outlay to greatest extent with the outer fissure inwall.
In order to improve plant factor more fully, the present invention will be provided with mud water distribution regulation system in the zone that form between second pond, two ditch type oxidation ditches, outer fissure inwall, so just more economical, the effect of the COD that disposes of sewage, BOD, ammonia, nitrogen, phosphorus is better than Carrousel oxidation ditch.When second pond and two ditch type oxidation ditches are tangent or during the shared portion wall, form two zones between second pond, two ditch type oxidation ditches, outer fissure inwall, the water inlet pipe in a zone is communicated with the sewage water inlet, rising pipe inserts outer fissure, be equipped with overflow weir on another regional outer fissure inwall, this district is built-in with the pipe connection second pond.When second pond and two ditch type oxidation ditches from the time, form a zone between second pond, two ditch type oxidation ditches, outer fissure inwall, in this zone, put divider wall, described divider wall is separated into independently two parts with this zone, a part is communicated with the sewage water inlet by water inlet pipe, rising pipe inserts outer fissure, is equipped with overflow weir on the outer fissure inwall of another part, and this district is built-in with the pipe connection second pond.
Among the present invention, for the ease of maintenance, add the propelling of current in the major groove, at each turning of organizing two ditch type oxidation ditches plate-spinning aerator or the surface aerating machine of falling the umbrella shape are set, perhaps be provided with micro-pore aeration machine and angle of rake combination in ditch, strengthened the mixed effect of air and water body greatly, oxygenation capacity significantly improves, particularly use powerful plate-spinning aerator, its plug-flow power is big, makes plug-flow apart from elongation, has strengthened the aerobic-anaerobic effect, help denitrogenation dephosphorizing greatly, in addition, the video disc of plate-spinning aerator is changed more easily than the aerator of falling umbrella shape replacing blade, and video disc is domestic has used anti-aging, erosion-resisting glass fiber plastic, longer service life.
The present invention also is equipped with the plate-spinning aerator in the outer fissure top at second pond place, to increase aeration effect and impellent.
The present invention places preliminary sedimentation tank or second pond between two ditch type oxidation ditch circular arc linkage sections and outer fissure, its complementary space that they form is arranged to treatment zone, entire equipment floor space, cost of investment are reduced to minimum, this compact equipment, total denitrogenation dephosphorizing effect height, good reliability, convenient management, maintenance cost are low.
