A disposal method for stoch rasing waste water availing leaf mould and apparatus therefor

摘要

PURPOSE: A treatment method of livestock farming wastewater using humus and equipment thereof is provided, in which wastewater pass through high speed separator(2), vibrating screen tanks(3,5), aeration tank(4), recycling route head drop tank(6) and gravel and sand filter(10) with humus added, so that water purifying effect is maximized by aerobic and anaerobic property, thus minimizing operating cost. CONSTITUTION: The method comprises the following steps: adds leaf mould to wastewater collecting tank(1); separate the wastewater into water molecule and sludge by high speed separator(2); remove by primary vibrating screen(3) sludge of more than 0.9 mm in diameter contained in sludge that is not separated by high speed separator(2); make molecular movement between water molecules by wavelength at aeration tank(4); separate fine sludge of 0.03-0.05 mm in diameter contained in foreign material that is fallen to pieces at aeration tank(4) by secondary vibrating screen(5); conduct separation of water molecules and suspended matter by finely dividing molecules by a strong head drop; conduct a complete separation of water molecules and suspended matter by enhancing oxygen content; coagulate suspended matter of homogeneity, settle and float to separate at stabilizing tank(8); filter suspended matter again; remove iron containing foreign matter at a 'Z' letter type magnetizing reaction tank(10); remove harmful material and residual color to sterilize by feeding heavy oxygen at low temperature reaction tank(11); and remove residual harmful color.
