FALL TYPE DIVERSION WORK OF WASTE WATER PURIFICATION DEVICE WITH SOIL MULCH TYPE

摘要

The present invention relates to a method and apparatus for purifying sewage, manure drainage, and sewage using soil microorganisms and soil animals of the surface natural ecosystem, and in particular, permits the quality of the final discharged water by aeration by a waterfall-type filter tank. The present invention relates to a cascade-type fountain of soil-coated sewage purification apparatus that maintains below a standard value and facilitates maintenance.;Pretreatment facility, anaerobic decay tank, primary treatment device (10), aerobic filtration fountain tank, secondary treatment device (20), filled with contact agent, tertiary treatment device (30), which is a flow-through infiltration trench structure, and soil type filter In the soil type sewage purification apparatus for purifying the sewage, such as manure, household wastewater, using the soil microorganisms and soil animals of the natural ecosystem, including the fourth treatment device 40 consisting of and a scavenger (45), the secondary The treatment apparatus 20 forms a main fountain 22 and a waterfall fountain 24 'in which the sub fountain 23 is divided into both sides of the main fountain in the center of the partition 21. The fountain tank 22 and the sub fountain tank 23 are connected to each other through a plurality of connecting pipes 25, and the discharge hole 26 formed in the sub fountain tank 23 is predetermined from the end of the connecting pipe 25. Falls of soil-coated sewage purification apparatus characterized by the configuration that is located downward by the length Min tank.
