Description

Vessel for purifying sewage using charcoals and pebbles and small sewage purification facility}

The present invention relates to a sewage treatment plant, and more particularly, to a sewage treatment tank using charcoal and gravel and a simple sewage treatment plant using the same.

In general, charcoal is known to have excellent filtration. Hereinafter, the structure and features of such charcoal will be described. Burning wood produces about 25-30% of the charcoal and 5% of the grass is incidentally obtained. In the case of charcoal, the high and low alkali is determined by the baking temperature, which is used to improve acid soil and counteract acid rain. The pore inner surface area of the char thus obtained has a cross-sectional area of 200 to 400 square meters per gram of char. The pores inside the charcoal have a variety of sizes up to one millionth of a millimeter and have a structure that is very suitable for microorganisms to grow, which is very advantageous for propagation of beneficial microorganisms such as bacteria and actinomycetes.

The filtration function and effects of such charcoal will be described below. Since ancient times, charcoal has been used to remove dirt from our lives, and charcoal was used to purify soy sauce and Dongchimi. Passing through air and water contaminated with charcoal provides an amazing cleansing effect. The strong water purification of charcoal is possible because the interior of the charcoal is a porous structure with various sizes and surface areas mentioned above. For example, charcoal is also contained in a gas mask that poisons poison gas. Charcoal is effective in eliminating the smell of tap water and supplying minerals that improve taste. This is also the effect of the structural characteristics of charcoal, the interior of the porous charcoal inside and out through up and down, so that water or air is easy to pass through, and the water is in contact with the air has a great adsorption power. Therefore, charcoal has infinitely adsorbing various disinfectants or organic substances that are the basis of pollution. Excellent adsorption of heavy metals and pollutants, water purification and purification. It has the function of reducing organic compounds and other pollutants.

Accordingly, there is disclosed a purification facility using charcoal (Patent Application No. 10-2000-13803). As shown in FIG. 1, the charcoal mesh 2 is put into the water to purify the water quality, but since there is no screen device, the suspended solids are not removed, and thus the factor that does not smooth the flow of water to hinder the filtration of the charcoal. When the entire river is blocked, the volume of the charcoal is large and there is a disadvantage that the desorption is not easy.

In addition, as shown in FIG. 2, there was a conventional sewage treatment facility that blocks the entire stream. However, the screen device 1 using a mosquito net to purify the water quality by inserting a charcoal net 2 'into the water. Although it is used, this also has the disadvantage of preventing the flow of water to the charcoal (2 ') easily because it is not easy to remove the suspended matter filtered by the screen device (1), the charcoal (2') is also bulky and easy to remove. There was a disadvantage. In addition, the pollutant removal effect of the existing purification plant was analyzed as shown in Table 1 below. In Table 1, BOD means biological oxygen demand, COD means chemical oxygen demand, TN means total nitrogen, and TP means total phosphorus. Here, TN and TP are known as representative eutrophicants in rivers and lakes. Therefore, the increase of nitrogen and phosphorus in the lake or river will adversely affect the water quality. For example, when eutrophication occurs, red tide occurs and floating algae multiply, reducing the aesthetic value. If water from contaminated lakes and freshwater lakes is used as a water source, tap water causes taste and smell. When higher fish species die out and large quantities of algae or aquatic plants die, they are rapidly degraded, producing odors and consuming large amounts of dissolved oxygen. When eutrophication occurs and algae is multiplying, the water quality deteriorates. Therefore, if the concentrations of TN and TP are reduced in polluted streams, the effects of eutrophication can be reduced.
