Abstract: The present disclosure provides a resource-circulation-type and eco-friendly livestock manure treatment method, and a system for producing algal biomass used therein, the method being capable of: preventing water pollution while allowing livestock liquid fertilizer to be treated on the basis of a biological process; producing algal biomass; and supplying the produced algal biomass to livestock feed and farms.

Abstract: A hazardous gas purification device with a built-in purification system is disclosed.

Abstract: Provided is a method of providing a user-optimized laboratory environment. The method includes receiving user location information and user experiment information from a user terminal, receiving location information of laboratory equipment and internal environment information of a laboratory from a plurality of sensors, providing experiment guide information to a user on the basis of the user location information, the user experiment information, the location information of the laboratory equipment, and the internal environment information of the laboratory, and controlling the laboratory equipment on the basis of the user location information, the user experiment information, the location information of the laboratory equipment, and the internal environment information of the laboratory.

Abstract: The present invention relates to a neutralizing absorbent for decontaminating a leaked chemical substance, a method of preparing the same, and a neutralizer filled with the same. The neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention includes an inorganic adsorbent, which is commonly usable in neutralizing absorption of acidic, basic, and/or organic chemical substances, at 40 to 60 wt %, a thickener at 20 to 30 wt %, a surfactant at 20 to 30 wt %, and a color change indicator, and is formulated in a solid state. The neutralizing absorbent is effective in promptly and safely taking an initial action regardless of the type, nature, and characteristics of acidic, basic, and/or organic chemical substances leaked in the leakage accident of the chemical substance, and accordingly, is useful in preventing secondary accidents.

Abstract: The present invention relates to a reagent refrigerator which comprises a reagent refrigerator compartment including reagent storing trays; an upper housing a cooling equipment compartment and a cooling purification compartment; a side duct defined by a side partition having a through hole at the side of the reagent refrigerator; one each of a second side duct, separately defined by a side partition having a through hole at the other side thereof, and a rear duct, separately defined by a rear partition having a through hole at the rear side thereof; and an upper duct having one end communication with the upper portion of the second side or rear side, and the other end communicating with the cooling purification compartment. Accordingly, refrigeration temperature of the reagent refrigerator can be controlled, and circulation flow in the reagent refrigerator is improved, to thereby purify the air therein and minimize deviations from refrigerator temperature values.

Abstract: An apparatus for purifying and neutralizing toxic gases such as odors, fumes or various volatile organic compounds generated by research laboratories, chemical processing factories or hospitals where medicinal products are handled, comprises a main body having an intake, an exhaust and a control panel; a pre-filter, a first filter, first and second neutralizing pellet beds, and a second filter which are mounted in the apparatus main body and are placed from the intake to the exhaust in that order; and a blower and a driving device placed between the first and second neutralizing pellet beds. The apparatus effectively purifies and neutralizes toxic gases and collects fine particles or dust.
