METHOD FOR UNDERGROUND DISPOSAL OF LIQUID DOMESTIC WASTES AND RAIN-FALL DRAINS

摘要

environmental control. SUBSTANCE: method involves geological and geophysical investigations of rocks to discover natural local isolated voids encircled by low-penetrating rocks, for example, basalt rocks and injection of liquid domestic (fecal) and rain-fall (atmospheric) drains in mentioned voids; gaseous materials of biological decomposition are conveyed through especially bored second hole for their future recovery. Domestic wastes and rain-fall drains handled by proposed method are not only to disposed but also recovered and purified with minimal cost because their anaerobic treatment does not require building special tanks or creating specific conditions: such conditions are created by nature. In addition, biological decomposition products may be recovered to organize enclosed wasteless process cycle. Natural local isolated voids are usually large in size which provides for using them during long period of time. EFFECT: reduced cost; provision for organizing wasteless process cycle. 1 dwg
