<p>PURPOSE: A circulation system for treating excrement, sewage and wastewater is provided to completely degrade thus remove solids and purify wastewater to reuse the purified wastewater by passing excrement, sewage and wastewater through catchment tank, aeration tank, sediment tank, storage tank, first filtering tank and second filtering tank. CONSTITUTION: In a circulation type system for treating excrement, sewage and wastewater comprising catchment tank(41), aeration tank(42), sedimentation tank(43), storage tank(44) for storing excrement, sewage and wastewater, first filtering tank(45), second filtering tank(46), storage tank(47) for storing filtered water, and a use place(40), the circulation system is characterized in that the first filtering tank containing the filter medium and the second filtering tank containing the activated carbon are formed in a cylinder shape having certain diameter and length, the inside of the cylinder shape is divided into at least two or more of stages by porous plates, a certain space is secured between the divided parts, an oxygen supply pipe is arranged horizontally in an upper part of the filter medium of the first filtering tank divided into two or more of stages and vertically in a central part of the first filtering tank, and water tanks(45b,46b) are installed under the first filtering tank and the second filtering tank respectively to receive and store corresponding filtered water.</p> |
