Description

Activated carbon pretreatment device and anaerobic bioactive carbon manufacturing method using same

The present invention is an activated carbon pretreatment device and an anaerobic bioactive carbon production method using the same, and in more detail, an activated carbon pretreatment device and an anaerobic system using the activated carbon pretreatment device that creates an optimal environment for the growth of anaerobic microorganisms to promote the production of biogas containing methane It relates to a method for producing bioactive carbon.

In general, due to the recent increase in population, industrial development, and improvement in living standards, discharges of various types of organic wastewater such as domestic wastewater, industrial wastewater, livestock wastewater have increased rapidly, resulting in serious water pollution in rivers, rivers, lakes, and seas. It is reaching the point. In particular, chemical treatment methods and biological treatment methods are used as methods for purifying organic substances that are the main cause of water pollution, but chemical treatment methods tend to prefer biological treatment methods using microorganisms, which are relatively inexpensive to operate, because equipment and chemicals are expensive. to be.

However, the biological treatment method is a method in which microorganisms decompose organic substances, and it takes considerable time for microorganisms to decompose organic substances, and stable treatment water quality due to deterioration in precipitation efficiency and difficulty in operation due to sludge injury in a sedimentation tank that separates solids and liquids As it is difficult to secure, recently, a technique for adsorbing and removing contaminants using activated carbon has been developed.

Here, activated carbon is a material mainly used as an adsorbent, and contaminants adsorb on the surface of each activated carbon when bacteria, microorganisms, etc., pass through the activated carbon column as well as pollutants made of various organic or inorganic materials. As such, activated carbon has a large specific surface area, a large adsorption capacity, and has excellent characteristics for removing pollutants with excellent adsorption ability, and is very cheap compared to other treatment methods. However, since the surface is non-polar, it is known that a boiling point such as ammonia is low and adsorption efficiency is low for polar components.

Accordingly, in the prior art disclosed in Korean Patent Registration No. 10-1407506, “Pretreatment method of carbon raw material for the production of activated carbon,” impregnated with an acid or alkali on the surface of the pores in order to increase the adsorption performance, and then selectively increase the adsorption performance to select specific components. Although a method of producing activated carbon capable of adsorbing is disclosed, it is costly and time consuming because a large amount of water is consumed in order to clean chemicals and the washed water must be treated again, and activated carbon is possessed by a strong chemical reaction. The inherent adsorption ability was destroyed, and the removal efficiency of pollutants fell.

In addition, another prior art patent registration No. 10-1564368 "Compound Microorganism Attached Activated Carbon Manufacturing Method" relates to a composite microbial attached activated carbon manufacturing method. Although the composition has been pre-registered to maximize the water purification ability by controlling and inoculating and inoculating microorganisms, the proliferation rate is greatly reduced when inoculating anaerobic microorganisms due to the gas (oxygen) remaining in the activated carbon pores. Since it is a dedicated purpose for improving the purification ability, it is a general purpose anaerobic bioactive carbon that produces biogas along with decomposition of organic matter, which is impossible to apply.

In the present invention, in order to solve the above-mentioned problems in the prior art, a new technique was devised, and the removal rate of gas (oxygen) remaining in the pores of activated carbon is excellent due to the circulation structure of the hot water in the heating chamber of the pre-treatment device, thereby proliferating anaerobic microorganisms.
