The present invention relates to a wastewater treatment boiler, and more particularly, to collect and heat food waste wastewater to obtain high heat steam, and the steam can be utilized for various purposes such as sludge drying, and the steam-cooled condensate contains an alcohol component. The present invention relates to a device that can be used as an additive to activate sludge in an aeration tank of a wastewater treatment plant.

To date, leachate generated from food has failed to treat wastewater with BOD of 80,000 ~ 100,000 PPM, and the wastewater generated from food is linked to the influent of large sewage treatment plant.

However, in the small-scale sewage treatment plant, the small-scale sewage treatment plant cannot carry out the above-mentioned treatment process.

Therefore, the waste water as described above poses a serious problem such as polluting the stream. Unlike general industrial waste or household waste, the moisture contained in the food waste is collected and transported by the food waste. And because of the natural fermentation in the course of processing, bad smell.

However, the above food wastes contain a large amount of water in the food cooking process or the food waste processing process, and the process of collecting and processing food wastes takes at least several days to several tens of days. It is naturally fermented and contains a certain alcohol component and can be recycled. To recover the alcohol component and water, a heating method is used, and the heat of the heated water can be naturally cooled in a process used for other processes. The heat needed to heat the moisture can be used in various ways beyond simple heating.

The present invention relates to a wastewater treatment boiler, and more specifically, to collect and heat food waste wastewater to obtain high heat steam, and the steam can be used for various purposes such as sludge drying, and the condensed water, which is cooled steam, contains some alcohol. The present invention relates to an apparatus for utilizing as an additive to activate sludge in various wastewater treatment plants.

To this end, the present invention, in order to treat the wastewater discharged from food waste, a power source for transmitting power to the device, a shaft that rotates in response to the power provided from the power source, installed on the shaft so that the wastewater can move freely One or more inlets installed to perform a function of a screw vane perforated to the outside, a sheath installed outside the wing and the shaft, and installed in the sheath to perform a function of an outflow passage of steam generated by inflow or heating of the wastewater, and the wastewater It comprises a scale outlet for continuously discharging the scale generated therein to discharge to the outside by turning the screw, the provision of a heat source for waste water heating to the device is provided a heat source or a separate heat source integrally formed with the device. It is characterized in that the heating to the outside, In order to be able to determine the quantity of waste water from the outside which is a feature that the water level be installed on certain parts of the exterior of the device it is further added to the system.

Hereinafter, the configuration and structure of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall perspective view of a wastewater treatment boiler and a scale removing apparatus according to the present invention, the basic function of which is the wastewater inlet 20 through which the wastewater can be introduced and the scale generated when the wastewater is heated; The steam outlet 21 and the inside of the housing configured to discharge steam to the outside when the steam is generated is heated and 70 is directly supplied to heat the waste water by receiving heat energy from the heat source of the heat generated It comprises a motor 10 for rotating the installed screw blades and a water gauge 40 to check the flow rate of the injected waste water.

Here, it is preferable to attach a valve to the wastewater inlet, the steam outlet, and the scale outlet in order to selectively open and discharge the inflow and outflow of the wastewater during the use process.

Figure 2 shows the characteristics of the screw blades according to the present invention, the screw blades are drilled in a certain hole serves to allow the waste water to move more freely in the boiler, free movement of the waste water through the rotation of the screw If the operation for a certain period of time to help to move the scale generated from the food waste water can be discharged through the scale outlet (30).

3 is an internal structural diagram of the apparatus according to the present invention, which is different from a general screw conveyor, in which a screw hole 50 is first drilled so that the waste water can freely move inside the boiler.

In addition, when the waste water is heated, a scale is placed on the surface of the boiler, and the function of removing the scale can be removed by a process that allows the screw blades to be scraped while rotating.

Looking at the operation of the device, first, the wastewater is introduced into the boiler through the wastewater inlet, and the wastewater can be checked the water level through the water gauge, and the valve is installed in the scale outlet so that the valve is blocked. do.
