Description

Air melting tank for movable sludge dehydartion processing system

The present invention is installed between the reaction tank for separating the sludge and liquid in the manure sucked from the septic tank by the sludge treatment system mounted on the vehicle, and the separation of the floating from the reaction tank, which is installed between the liquid separation tank for removing the separated matter from the liquid. Purification of mobile sludges to improve the efficiency of separating sludges and liquids by supplying pressurized water in a vortex state in which external air is dissolved to sludges moved to the tank. A pressurization and air melting tank for a dewatering treatment system.

In general, in residential complexes such as buildings or apartments, large septic tanks for collecting manure discharged from the toilets of each household are buried and sludge containing manure accumulates. After moving to an environmental establishment, it is processed through physical and biological steps.

As a result of the continuous friction with neighboring residents due to the bad smell generated during the post-treatment of the collected manure at the environmental establishment, it is difficult to install and operate the environmental establishment. In the case of an apartment, the processing cost is directly shared by the tenant, and therefore, there is a problem of experiencing an economic burden due to an increase in management costs.

Meanwhile, a mobile scum and sludge dewatering treatment device is posted in Korean Patent No. 300021 (Application No. 1999-20752), which is loaded on a septic tank in which dirt such as scum and sludge is collected and loaded on a vehicle. And collects the contents contained in the septic tank by pumping force, but collects the foreign matter, and connects the tubular body to the collection tank and separates the dust and liquid from the collected waste, and separates the first and second separation tanks separated by partition walls, and Odor to the first solution tank containing the solution which deposits the dust of the dirt contained in the first separation tank and the liquid waste overflowed in the first separation tank through the first separation tank. A second solution tank containing a solution for removing the solution, a reservoir connected to the second separation tank with a tubular body, and a container containing dry matter and liquid dirt introduced therein; and a pipe for one side of the storage tank. It is connected to the ingredients of the waste flowing into the inside thereof is compressed and that the liquid has a compression dehydration tank to drain.

In addition, the removable scum and sludge dewatering treatment device is installed between the second separation tank and the dehydration compression tank, and supplies a pressurized flotation tank that floats the mass in the sludge by supplying air to the sludge and the liquid phase moved from the second separation tank. Although it is further provided, as the compressed air discharged from the pump to raise the lump contained in the sludge is stored in the pressure tank in a static state through the pipe to the upper portion of the pressure levitation tank, bubbles are generated inside the pressure levitation tank. This decreases the flotation rate of the mass separated from the sludge, which limits the amount of sludge.

Therefore, the object of the present invention, by supplying the pressurized water in the vortex state of the external air dissolved in the flotation tank from the reaction tank that separates the manure sucked from the septic tank into the sludge and the liquid to reduce the amount of bubbles generated in the flotation tank It is to provide a pressurized and air melting tank for mobile sludge purification and dewatering treatment system to increase the separation rate of sludge and liquid with increasing.

Another object of the present invention is to provide a pressurized and air melting tank for a mobile sludge purification and dewatering treatment system that minimizes sludge discharge collected and collected in a septic tank to prevent environmental pollution, and reduces tenants' contributions. will be.
