(a) Field of the Invention
The present invention is related to an improved structure of a purification carrier input of a sewage scum removing unit, and more particularly, to an organized layout configuration of an improved installation structure to achieve upgraded cleaning function by the purification carrier.
(b) Description of the Prior Art
A tank to accommodate sewage is usually provided in a structural configuration of sewage scum removing unit of the prior art. Air bulbs are pumped into the tank for pollutants in the sewage to get attached to those air bulbs and float up to surface level and to form a scum suspension layer, and the scum suspension layer is then removed. This sewage disposal method allows recycled use of water resources, reduction of water consumption, and thus saving water resources; therefore, this method is massively applied in aquaculture industry, sewage process plant, and secondary use of consumer water.
It is understandable that additional to the tank and the structure to pump into air bulbs as described above, a mixing device is further disposed to intensify contact of air bulbs with pollutants for the general scum removing unit to more effectively remove pollutants in the water; furthermore, the sewage to be processed may be added into a material that is capable of absorbing contaminated substances, e.g., a polymer carrier to absorb toxic substance or a specific pollutant; and as aided by the mixing device, the capacity of absorption of pollutants in the water is improved to avail cleaner water for secondary use.
In a typical sewage treatment procedure, an air-liquid mixing device is provided to pump air bulbs into the water or a mixing device is operated to pat the water for pumping air into the sewage; and the polymer carrier to clean pollutants in water functions to absorb specific pollutants in the sewage or to create a structure that is capable of retrieving air bulbs in water thus to form jointly with air bulbs a structure that is capable of removing particle pollutants. However, the polymer carrier is of a comparatively weak structure and the cleaning structure created in the water would be easily destructed in the course of generating air bulbs in the sewage or patting the water to compromise the function of absorbing pollutant otherwise the carrier is expected to function. Should the sewage scum removing unit of the prior art be redesigned to give it different organizational layout, the cleaning results provided by the polymer carrier will be improved, thus to further improve the overall efficiency of sewage filtration.
The primary purpose of the present invention is to provide an improved structure to input purification carrier for a sewage scum removing unit by having the purification carrier disposed in such a way that the purification carrier is added into the sewage only upon completing the air liquid mixing operation in a filtration process so that the purification carrier would be able to bring its absorption efficacy into full play under a mild current.
To achieve the purpose, the improved structure of the present invention includes a first tank having a water inlet to introduce in sewage disposed beneath the first tank; a water outlet disposed at a predetermined location on the first tank to lead sewage out of the tank and a first conduit is disposed to lead the sewage to a second tank for curing; a carrier introduction end is disposed to the first tank at where in the peripheral to the water inlet of the tank for introducing in polymer carrier to clean the sewage; the water inlet is connected to an air water mixing device for the sewage to first go through an air bulb addition process before being admitted to mix with the polymer carrier to correct the flaw that molecular structure is vulnerable to be destructed by pressure or externally applied force as found with the prior art.
Referring to
In the preferred embodiment, the first tank 11 is made in a form indicating a smaller diameter, long and narrow body; and to facilitate uniform distribution of air bulbs and contamination removing substance in the sewage, a regulation device 30 containing a mixer is disposed in the first tank 11 so that when the sewage flows through a route created by a narrow space of the first tank 11, the regulation device 30 will sufficiently and uniformly disperse air bulbs and pollutant removing substance in the sewage before being discharged out of the water outlet 15 disposed on an upper portion of the first tank 1.
As illustrated in
Once the water level rises up to approach a top position of the first tank 11, the sewage flows out of the water outlet 15 to enter into the conduit 13; and the sewage containing fully mixed air bulbs and polymer carrier 40 is led through the conduit 13 into the second tank 12, which in a wider and more spacious profile or construction. After having sufficient mixing with the polymer carrier 40 absorbed with air bulbs, the sewage gradually floats and coalesces towards surface level in the second tank 12 while the purified water is settling down in the second tank 12. The polymer carrier absorbed with air bulbs and pollutants is gradually overflowing out of a scum removal trough 17 disposed to upper portion of the second tank 12 or externally scraped with an aid from a scarping device 50 disposed on the second tank. Meanwhile, the descending clean water is led out from a water outlet 18 disposed at a lower end of the second tank 12 for use.
The sewage and those substances used to remove foreign matters in sewage water are fully regulated before being introduced into the second tank 20 for curing to separate water from pollutants after sedimentation. Substantially, a structure to supply and operate the polymer carrier 40 is set to be executed after air bulbs are pumped into the sewage so to free the polymer carrier 40 from being affected by the pressure produced upon pumping air bulbs into the sewage or interfered by external force applied in the course of patting the water to damage the structure of the polymer carrier 40 mixed in the sewage and further to compromise efficiency of the polymer carrier 40 to absorb pollutants.
Accordingly, the improved structure of a purification carrier input for a sewage scum removing unit of the present invention by redesigned the layout configuration for the introduction end 16 of the carrier does correct the problems of damaged structure of the polymer carrier due to blending and frustrated cleaning efficiency as found with the prior art to realize the purpose of upgraded pollutant removing results in showing a very significant progress.
However, it is to be noted that the preferred embodiments disclosed in the specification and the accompanying drawings are not limiting the present invention; and that any construction, installation, or characteristics that is same or similar to that of the present invention should fall within the scope of the purposes and claims of the present invention.
