Description

Cement brick for purifying water using microorganism and zeolite, and method for preparing the same}

The present invention relates to a cement brick for water purification using microorganisms and zeolites and a method of manufacturing the same.

Recently, the river environment, which is a major element of the national environment, has deteriorated rapidly, and the resulting social problems are more serious than the environmental problems of other national elements such as forests, forests, and agricultural land. In particular, since the 1970s, Korea has continued to increase the amount of water consumed by rapid industrialization and urbanization, and the increase in the amount of domestic sewage has increased the inflow of nutrients into the surrounding water system, resulting in eutrophication and natural purification of the aquatic ecosystem. Exceeding the capacity caused the loss of biodiversity. In addition, it takes a huge cost and time for sewage maintenance and high-level wastewater treatment, and lakes and rivers in Korea are easily exposed to pollutants, so it is known that eutrophication can occur easily.

Therefore, bioremediation using various functions of microorganisms or organisms has been attracting attention as an environmentally friendly and economical water quality improvement measure to solve the serious water pollution.

Microorganisms have the ability to decompose many environmental pollutants without the generation of intermediate toxic substances, and by applying them to porous concrete with continuous voids, the adsorption biomass is increased, so that the microorganisms themselves can be adsorbed by adsorbing pollutants by adsorption organisms. It is reported that the ability can be promoted and increased. In addition, by using microorganisms known to be excellent in organic decomposition and excellent in adaptability to the environment, they are adsorbed to concrete blocks and structures installed in water or watersides to form biofilms. Research on eco-friendly concrete using useful microorganisms such as rapidly and continuously decomposing large quantities of organic materials, absorbing and removing nitrogen and phosphorus, is continuously conducted.

However, the water purification of concrete or cement brick using conventional microorganisms is generated by adding the microorganisms to the concrete or cement bricks, thereby reducing the survival rate of the microorganisms due to the toxicity of concrete. The water purification effect could not be greatly expected.

In order to overcome this problem, many researchers have been trying to maximize the water purification effect by the microorganisms by forming the concrete structure to support the microorganisms when forming the concrete structure. For example, Korean Patent Publication No. 10-948556 discloses water quality purification concrete using microorganisms that can increase the survival rate of microorganisms when concrete structures are formed by supporting and dormant spores with microorganisms excellent in alkali and heat resistance. A block manufacturing method and a concrete block produced thereby are described.

Recently, the interest in environmentally friendly materials has been increasing rapidly, and the utilization of porous concrete having both structural functional and permeability of materials is increasing.

Therefore, by utilizing the ability to decompose many environmental pollutants without generating intermediate toxic substances of microorganisms, the microorganisms are adsorbed to porous concrete with continuous voids to increase the adsorption microorganisms, and by adsorbing contaminants by the adsorption microorganisms, There is an urgent need for the development of cement blocks that can maximize water purification effects by promoting and increasing self-cleaning capacity.

The inventors of the present invention, while studying a cement block that can maximize the water purification effect, by dipping and curing the cement brick containing zeolite in the water in which microorganisms are dispersed, by adsorbing the microorganism to the zeolite, to the cement brick that does not adsorb microorganisms It was confirmed that the removal efficiency of contaminants in the contaminated water is excellent, and completed the present invention.

The water purification experiment tank used a 25 L acrylic bath, and the quantity of the reaction tank was adjusted to 20 L and the water was circulated using a pump. Three reaction tanks were prepared, and cement bricks (Comparative Example 1, WB [raw water + cement brick]) in which raw water and microorganisms were not adsorbed to each reaction tank, and cement bricks in which the microorganisms prepared in Example 1 were adsorbed (DB [ Raw water + cement brick + microorganisms (D101, D102, D103, D104, D105)], SB [raw water + cement brick + microorganisms (S101, S102, S103, S104, S105, S106, S107, S108, S109)], NB [ Raw water + cement brick + microorganisms (N101, N102)]) was placed in a water tank and water purification capacity was measured (see FIG. 3). The water purification experiment was conducted four times for two weeks. The dissolved oxygen (DO) of the solution was DO meter (DO-30N), pH was pH meter (P15), suspended solids (SS) was SS meter (AL250), chemical oxygen The requirements (COD) are reactor digestion (HS-2300Plus), biological oxygen demand (BOD) is BOD sensor system, total nitrogen (TN) is chromotropic acid (HS-2300Plus) and total phosphorus (TP) is Molybdo was also measured using molybdo vanadate (HS-2300Plus).

As shown in Table 5 and Figure 4, raw water, WB, DB, NB, SB all did not show a big change in the tendency to increase until the second day and then decrease again. Therefore, it was confirmed that the microorganisms do not affect the DO.

In addition, as shown in Table 6 and Figure 5, the pH of the raw water did not show a large change for two weeks, in the case of WB, DB, NB, SB showed a tendency to increase again until the 6th day but then decreased again Was not. However, since the pH of DB, NB, SB was increased compared to WB, it was determined that the microorganisms acted as an increase factor of the pH.

In addition, as shown in Table 7 and Figure 6, the concentration of suspended solids (SS) in the raw water did not show a significant change, but increased 4.1% from the initial concentration, 45.46% of the average suspended solids compared to raw water for WB not adsorbed microorganisms The removal efficiency of the material is shown. This is because the use of porous zeolites and porous cement bricks has a large specific surface area and voids in the interior, which may be effective in removing suspended solids from outside as well as inside. In addition, in the case of NB and SB, the removal efficiency of suspended solids was 69.2% on average than that of WB, and 77.8% on SB.

In addition, as shown in Table 8 and Figure 7, the removal efficiency of chemical oxygen demand (COD) of WB without the adsorption of microorganisms was 13.4% better than that of raw water, which is due to the influence of zeolite and porous cement bricks. It seems to have worked. DB was almost similar to WB, and NB and SB were 13.01% and 21.46% higher than WB, respectively. This is thought to be due to the degradability of microorganisms that live on the outside and inside of porous zeolites and porous cement bricks.

In addition, as shown in Table 9 and Figure 8, the biological oxygen demand (BOD) of WB, DB, NB, SB was 8.66%, 10.07%, 14.49%, 15.46% on average compared to the raw water, respectively.

In addition, as shown in Table 10 and FIG. 9, the total removal efficiency of total nitrogen (TN) of WB was 29.26% on average, similar to that of WB for DB, and 50.19% and 51.20% for NB and SB, respectively. Indicated. It is determined that the biofilm is well formed inside or outside of the zeolite and cement brick, so that nitrogen is removed by the nitrifying microorganism having a high bioconversion rate.

In addition, as shown in Table 11 and Figure 10, the removal efficiency of the total phosphorus (T-P) of the WB was 37.5% on average, the average was 48.1%, 62.85%, 64.85% for DB, NB, SB, respectively.

As described above, the cement bricks (DB, NB, SB) that adsorbed the microorganisms have a higher pH than the cement bricks (WB) that do not adsorb the microorganisms, and include suspended solids (SS), chemical oxygen demand (COD), and biological activity. It was confirmed that the removal efficiency of oxygen demand (BOD), total nitrogen (TN) and total phosphorus (TP) is excellent.
