Description

[0001] The present invention relates to a sludge treating apparatus,

The present invention relates to an apparatus for separating and treating contaminants, and more particularly, to a sludge treating apparatus.

As we know, the problem of wastewater treatment is getting more and more important as the emission of pollutants increases due to industrial development, population increase and improvement of living standard. At present, the amount of daily wastewater generated in our country reaches about 5 million tons, and the amount of wastewater discharged per day to rivers and sea is about 3 million tons.

In addition, the amount of daily sewage generated is currently 2 million tons per day. In addition, daily production of livestock wastewater is currently 150,000 tons.

Also, in the treatment of wastewater, it is necessary to monitor concentration of various pollutants in the treatment process in each reaction tank. In case of discharged water, it is required to keep below the standard value, which requires cost, time and manpower consumption.

On the other hand, the wastewater has a sludge separating solids from the liquid during the treatment of wastewater and water, and the sludge is formed into a mud by sedimenting suspended matters in the water.

Since the sludge contains a large amount of water and is difficult to handle, it is treated with sand filtration, a filter press, a vacuum filter or the like to make a sludge cake having less moisture.

At this time, the cake must be buried, the concrete hardened, incinerated or discarded in the sea, or reused in case of failure.

However, there is a risk of secondary contamination in the method of burying, and there are some cases in which incineration is difficult, and a method of reuse is not established many times, and the treatment is often difficult.

In order to solve the above-mentioned problems, many conventional apparatuses for treating sludge of wastewater have been filed and developed. Among them, sludge as a pollutant is removed by using a solid-liquid separation technique by physical, chemical and biological treatment There was a device to remove.

However, the above-described conventional technology has a problem that a large amount of waste water can not be cleaned quickly, and the maintenance cost is high.

In addition, in order to purify the ozone and wastewater containing solids as well as organisms and microorganisms, it is necessary to add more chemicals, and the operation cost and the maintenance cost are increased.

In addition, filtration method or micro filter method is used to remove algae and fine suspended particles. However, because of the nature of the filter, it is impossible to use the filter continuously for a long time. As the time passes, the treatment efficiency decreases and the micropores of the filter become clogged. Back wash or the filter itself needs to be replaced, thus wasting unnecessary time, manpower and cost.

Particularly, as shown in FIG. 4, the communication hole 224 provided in the second shaft pipe 122 is mainly disposed on only one side section in the longitudinal direction of the second shaft pipe 122, The gravity sensor 265 is used to ascertain the position of the communication hole 224, so that the high-pressure fluid can be supplied only to the lower portion.

That is, the heavy sludge in the contaminant is positioned at the lower part as time passes. In this case, the smooth rotation of the second screw part 125 or the sludge removing operation can not be smoothly performed. In this case, the high-pressure fluid is supplied to the predetermined position, particularly, the lower side by using the gravity sensor 265 and the communication hole 224, so that the smooth rotation of the second screw part 125 and the sludge processing operation can proceed .

Although not shown in this embodiment, it goes without saying that the application of the communication hole 224, the gravity sensor, and the like is also applicable to the first screw portion.
