Background technology
Advanced biological film zone sewage purification oxidation pond, as No. the 200410051577.1st, Chinese invention patent, name is called: " a kind of high-efficiency artificial wetland is handled the method for sanitary sewage " disclosed technical scheme: utilize biological film zone and aquatic animals and plants to organically combine, set up biological, ecological efficient sewage purification system, form benign ecological circulation, give full play to the self-purification of natural biology environment.Based on the above method, also there is the gas blower of employing water body in the aeration tank to be blown into air, makes the water body in the aeration tank increase oxygen level.The shortcoming of aforesaid method is that the through engineering approaches design is adopted in the aeration tank, and civilwork engineering quantity is big, system complex, and management difficulty is big, construction, running cost height.
Summary of the invention
At above-mentioned shortcoming, the utility model provides a kind of biological film zone sewage purification jet-flow aeration circulating oxidation pond, adopt jet aerator and circulation device in oxidation pond to oxygen supply of water body or adopt in the aeration tank that jet aerator is provided with outside oxidation pond behind the aeration by circulation device in oxidation pond to oxygen supply of water body.Jet-flow aeration have stir that the mixing ability is strong, oxygen transmission efficient height, with low cost, energy consumption is low, installation and maintenance are easy, need not to set up advantage such as air blast machine room, oxygen level in the timely evenly temper oxidation pond of circulation device in the water body, for biological film zone is built good environment, recover the water ecology balance rapidly and continue to purify water the species diversity in the development water body.
The purpose of this utility model is achieved in that the circulating oxidation pond of biological film zone sewage purification jet-flow aeration is made up of oxidation pond, biological film zone, jet aerator and circulation device.Biological film zone, jet aerator, circulation device are located in the oxidation pond respectively, also can be in the outer setting aeration tank of oxidation pond, jet aerator is located in the aeration tank, stretch in the aeration tank by circulation tube, the water side of submersible pump is communicated with the aeration tank by pipeline simultaneously, forms oxidation pond and the circulating oxidation pond of aeration tank bonded biological film zone sewage purification jet-flow aeration.
A, oxidation pond
Oxidation pond can be cement structures, Tu Tang or constitute with other material.Oxidation pond can utilize the transformation of natural pond to form, and its shape designs according to actual place.The oxidation pond degree of depth is 1 to 4 meter, and dwell time of sewage is 1 day to 60 days.Be respectively equipped with sewage inlet and treated water outlet in the oxidation pond both sides, a plurality of entrance and exits can be set, to realize water distribution uniformity.Be provided with in sewage inlet the place ahead simply every the slag device, remove the solid refuse in the sewage.
B, biological film zone
Biological film zone is a currently available products.Biological film zone is the core of entire sewage treatment system as the high-effective microorganism carrier, because it has huge specific surface area, can develop and the microflora that biomass is huge, species are abundant, by the metabolism of microorganism pollutent is decomposed.In the utility model, on float formula and under float the formula biological film zone and all can adopt.Biological film zone reasonably is arranged in the oxidation pond, and its consumption, ratio and decoration form are decided with the current attitude in concentration, processing requirements and the oxidation pond of sewage.
C, jet aerator
Jet aerator adopts currently available products, and its effect is oxygenation in water, improves the decomposition efficiency of microorganism to pollutent.Behind a large amount of air admission trunnions of jet aerator by the airway suction, under the effect of water spray pressure, be divided into a large amount of small bubbles, form mixture with water.Gas liquid mixture discharges by diffuser tube, and its speed slows down, and pressure strengthens, and forms powerful injection stream, and sewage is stirred oxygenation.Jet-flow aeration have stir that the mixing ability is strong, oxygen transmission efficient height, with low cost, energy consumption is low, installation and maintenance are easy, need not to set up advantage such as Ventilator Room.The power of jet aerator is 0.5～20 kilowatt, and oxygenation capacity is 0.5～30kgO
2/ h, quantity is decided according to the sewage water yield and oxidation pond size.Jet aerator in the utility model also can be replaced by other forms of aerator.
D, circulation device
Circulation device is made up of submersible pump and the circulation tube more than 1, and submersible pump links to each other with the water-in of circulation tube respectively, and submersible pump is arranged near the diffuser tube exit of jet aerator.Submersible pump extracts nearby through the water of aeration aerating, the outlying place to the oxidation pond opposite side discharges by circulation tube, thereby has enlarged the aeration scope, and has promoted the water body circulation, has increased contacting of sewage and biological film zone.The submersible pump flow is 5～100m
3/ h, the quantity of submersible pump is identical with jet aerator.Circulation tube can adopt hard tube or flexible pipe, and material can be selected steel, PVC, PE, PPR etc. for use, and diameter is 5～20cm, and length is decided by the shape of oxidation pond, and the circulation tube outlet is fixed with support, makes the mouth of pipe upwards, in order to avoid dashed bed mud.Many cover jet-flow aerations and circulation device can be installed in the oxidation pond.
Except in oxidation pond, installing jet aerator and the circulation device, can also adopt the mode of outside aeration: outside aeration tank is set on the oxidation pond next door, outside aeration tank is the ground type structure, make the outside aeration tank water surface and the oxidation pond water surface form the discrepancy in elevation, outside aeration tank can be a cement structures, metal construction, Tu Tang or constitute with other material, the degree of depth is 1～4 meter, the positioned inside jet aerator, by submersible pump sewage in the oxidation pond is drawn into outside aeration tank, after sewage externally mixed oxygenation in the aeration tank, the outlying place to the oxidation pond opposite side discharged by circulation tube.
The utility model adopt jet aerator and circulation device in oxidation pond to oxygen supply of water body, jet-flow aeration have stir that the mixing ability is strong, oxygen transmission efficient height, with low cost, energy consumption is low, installation and maintenance are easy, need not to set up advantage such as Ventilator Room, oxygen level in the timely evenly temper oxidation pond of circulation device in the water body, build good environment for biological film zone, recover the water ecology balance rapidly and purify water.The utility model can be applicable to the purifying treatment of various dirty waste water, and management is simple, construction cost is low, energy consumption is low, is particularly useful for the improvement of country sewage because it is implemented.
