Abstract: PURPOSE: A parallel biofilter system that is capable of conducting adsorption process and decomposition process simultaneously is provided, which prevents secondary pollution due to saturated adsorbent. CONSTITUTION: The parallel biofilter system that consists of two biofilters comprises a first and a second biofilters(1,2); a first inlet pipe(3) through which polluted air flows into the fist biofilter; a first inlet valve(3-1) on the line of the first inlet pipe; a second inlet pipe(4) through which polluted air flows into second biofilter; a second inlet valve(4-1) on the line of second inlet pipe; a first purification pipe(5) through which purified air flows from the first biofilter into the second biofilter; purification valves(5-1,5-2) on the line of the first purification pipe; a second purification pipe(6) through which purified air flows from the second biofilter into the first biofilter; purification valves(6-1,6-2) on the line of second purification pipe; a first outlet pipe(7) through which air is vented out of the first biofilter; a first outlet valve(7-1) on the line of the first outlet pipe; a second outlet pipe(8) through which air is vented out of the second biofilter; a second outlet valve on the line of second outlet pipe. The biofilter is prepared by mixing activated carbon, compost and sawdust at the ration of 40:10:50 to 25:25:50(v/v/v); inoculating pseudomonas microbe to the above carrier, followed by cultivation at 20-40deg.C for 10-16 hours; packing the above carrier into filter housing and then sealing the filter housing.

Abstract: The long-lasting pesticide fertilizer is prepared by coating more than one layers of the fertilizer granule, which consists of a single layer or multiple layers of fertilizer and pesticide, with basic coating agent by 1-40wt% with respect to the uttermost inner layer. The basic coating agent is obtained by dissolving 0.5-50wt% rosin in a solvent. Additionally the coating agent involves less than 70wt% rosin derivative , less than 20wt% polymeric substance or both of them.
