Abstract:
1. A system for treating residual water characterized by being conformed through excavation in the land, presenting three segments, equipped with an anaerobic reactor, made with conventional construction materials or molded in a slope in the soil, such reactor consisting of a stonemasonry element, in the central portion of which is foreseen a tubing, and in the lower portion of which the inlet tubing is pointed and in the lower portion passage tubes are foreseen and next to the stonemasonry element conducting tubes are foreseen; such reactor may be built in a slope, molded in the soil, such reactor being equipped with a tubing, in the upper portion of which the inlet tubing is pointed and in its lower portion passage tubes are foreseen, while next to the slope conducting tubes are foreseen, such reactor being set up in the deep chamber, which presents an anaerobic pond at a higher plan, all the three segments in a single body covered by a blanket and protected by a cover blanket; laterally, gutters are built, which are used to anchor the lower and upper blankets providing the sealing, by means of steel or wood bars and screws, welded in such gutters, defining a water layer providing isolation and sealing; while in the lower blanket, at least four openings are foreseen, one in the frontal upper part for the inlet tubing passage of the affluent, a second tubing in the frontal part for the treated effluent outlet, a third lateral opening, and a fourth opening for the passage of the tubes which are used to remove the excess of mud generated in the reactor, whereas in such cover, which configures the biogas reservoir, at least two openings are foreseen, the first one for the installation of an outlet valve for the biogas and the second one is a passage for a safety valve.
