Abstract
The utility model discloses a solar hot air aeration device, which belongs to the technical field of wastewater aerobic biological treatment and aims at solving the defects that in the existing organic wastewater aerobic-process treatment process, odor gas overflows towards the space and the treatment efficiency in cold season is low. The solar hot air aeration device comprises an aeration tank, an air blower and an aeration tube, wherein at least one floating cover is covered on the wastewater liquid surface in the aeration tank; the floating cover is provided with a gas collecting tube; the gas collecting tube is connected with a gas collecting branch tube; the gas collecting branch tube extends to the inner cavity of the floating cover; one end of the gas collecting tube is sealed; and the other end of the gas collecting tube is communicated with a gas return tube at a gas inlet of the air blower by an anti-shrinking hose. The solar hot air aeration device is suitable for an aerobic biological treatment system for organic wastewater in food industry.
Description
Technical field
The utility model relates to a kind of sewage aerobic biologic treating technique, particularly relates to a kind of solar heat air-flow aerating apparatus.
Background technology
Food enterprise often has the sewage that contains organic pollutant in a large number and produces in the process of carrying out food-processing, according to the environmental regulation of China, these sewage must be through handling, and could discharge after wherein solvability organic pollutant is converted into innoxious substance.In order to save cost, food enterprise adopts biological treatment more, namely utilizes the metabolic processes of microorganism (mainly being some bacteriums and fungi) self, with sewage purification.The method of biological treatment of sewage mainly contains two kinds of aerobic treatment and anaerobic treatment.Because aerobic method has: processing efficiency height, reduced investment, management are easy; The microbe species that participates in handling enriches, can remove the more pollutent of kind; Can a large amount of nitrobacteria of growth in the sewage, therefore have a very high denitrogenation ability; To advantages such as the endurance of waterpower and organic pollutant load variations are good, stable, so in the sewage disposal of food service industry, aerobic method is used the most general at present.Investigate according to practice for many years, aerobic method is handled organic sewage still has the problem of following two aspects to have much room for improvement: the one, when sewage is constantly carried out aeration, there is a large amount of gas that has the stink peculiar smell to overflow from the sewage water body and intersperses among the space, can pollute atmosphere on every side, especially have under resident's the situation around the aeration tank, influence can be more serious; The 2nd, in periods such as late fall, winter, early springs, lower and the aeration tank of outside temperature all be build in outdoor, the air themperature that is provided to the sewage water body by blower fan also can be lower, low temperature makes the metabolic speed of the microorganism in the sewage slowly even stops, cause, hydraulic detention time prolongation slow to the oxygenolysis speed of organic pollutant in the sewage, have a strong impact on the efficient of sewage disposal.
Summary of the invention
The purpose of this utility model provides a kind of solar heat air-flow aerating apparatus, overcomes present aerobic method and handles that existing frowziness gas with foreign flavor overflows to the space in the process of organic sewage, colder processing efficiency in season is low wait not enough.
The utility model is achieved by following technical proposals.
The utility model comprises aeration tank, blower fan, aeration tube, sewage level in described aeration tank is covered with at least one floating cover, be provided with effuser, be connected to the gas collection arm on the described effuser, described gas collection arm feeds the inner chamber of described floating cover, and end sealing, the other end of described effuser are communicated with the muffler that is connected described fan air inlet by anti-flat flexible pipe.Now the aeration tank of general sewage biochemical treatment is all opened wide, though some added lid or on top scaffolding to wait also all be convenience in order to take shelter from rain or to operate for the staff, do not play other effects.In the technical program, the effect of described floating cover: the one, the air that emits in aeration process is collected, do not make excessive pollution space; When these air float in the sewage water body, be to pass through the sewage water body with the form of bubble, have only the outer field oxygen of bubble by microbial consumption, most of oxygen is all emerged with bubble; So in the air that emits oxygen level still very high.The 2nd, the heat that utilizes the sun to impinge upon described floating cover upper surface heats the air that is collected, these air pass through described gas collection arm, effuser, anti-flat flexible pipe and muffler after having improved temperature, after being blasted in the sewage in the described aeration tank by described blower fan at last, give the sewage water body with heat release, increase microbic activity, improved the decomposition efficiency to organic pollutant.
In the utility model, though it is seldom that air is blasted the oxygen that is consumed behind the sewage water body by described blower fan, but in continuous reuse process, the accumulation of consumption can make the airborne oxygen level of reuse reduce gradually, in order to replenish new oxygen by timely and appropriate discovery, at described muffler fresh wind tube and new air-valve are housed.For the surface of improving described floating cover to the water-intake rate of solar heat and reduce the thermal losses of reuse air on transfer line: the outside surface at described floating cover scribbles the black higher coating of rate, is provided with thermal insulation layer in the outside of described gas collection arm, effuser, anti-flat flexible pipe, muffler.
Against existing technologies, the beneficial effects of the utility model are:
The gas of emerging to the sewage water body is collected, and reduces excessive and to the pollution of surrounding space; Utilize sun power to improve the temperature of sewage water body, strengthen microbic activity, improve oxygenolysis speed.
Description of drawings
Fig. 1 is structural representation of the present utility model, and Fig. 2 is that the A of Fig. 1 is to view.Among the figure: 1, aeration tank, 2, blower fan 3, aeration tube, 4, floating cover, 5, effuser, 6, the gas collection arm, 7, anti-flat flexible pipe, 8, muffler, 9, fresh wind tube, 10, new air-valve.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Among the embodiment, the upper shape of floating cover 4 is circular arc to the utility model as shown in the figure, also can make to meet to the sun certainly simultaneously to be the shape on inclined-plane.Top and the peripheric surface of floating cover 4 all seals, and is blank below having only, and during enforcement, is inserted in the sewage of aeration tank 1 by a plurality of floating covers 4, has the slit each other.The effect that resists flat flexible pipe 7 is in order to adapt to because of the air top power increase and decrease in the floating cover 4, finally to make the position rising of effuser or the variation that reduces.Replenishing of new wind can realize that when replenishing new wind, unnecessary return-air amount can be released, and is less because of spillage, is not enough to surrounding environment is impacted by opening and closing new air-valve 10 at regular time and quantity from the slit of floating cover 4.
