Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a domestic sewage purification soil ditch and its construction method. Organic fibers are used to divert the flow, and countless diversion pipes are added to the soil, which improves the permeability coefficient of the soil and speeds up the process. The downward movement speed of sewage can reduce the stagnation of sewage in the upper layer of the soil; it can make domestic sewage including septic tank effluent reach the first-level discharge standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) , and can effectively prevent the system from clogging

Abstract

The invention discloses a soil ditch for purifying domestic wastewater and a construction method thereof, belonging to the technical field of environmental engineering. The soil ditch comprises a water inlet mechanism, a soil covering layer, a mixing layer, a soil layer containing bio-filler, a gravel layer, a fine sand layer, a water-resisting layer and a water draining mechanism, wherein the soil covering layer, the mixing layer, the soil layer containing bio-filler, the gravel layer, the fine sand layer and the water-resisting layer are arranged in from up down in sequence, the water inletmechanism is connected with the mixing layer, and the water draining mechanism is connected with the fine sand layer. The invention can ensure domestic wastewater including effluent of septic-tanks to conform to the first class discharging standard (GB18918-2002) in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant, and can effectively avoid blockage of ditch treatment system.

Description

technical field [0001] The invention relates to a device in the technical field of environmental engineering and a manufacturing method thereof, in particular to a domestic sewage purification soil ditch capable of preventing clogging and a construction method thereof. Background technique [0002] Soil trench method is a technology that can treat domestic sewage up to standard on site. Soil trench technology began in the United States in the 1970s. After more than 30 years of development, the U.S. EPA has promoted it as an important method for household sewage purification, and it has been used in nearly 21% of American household sewage treatment. applied. Due to the advantages of soil trenches in use, which do not require long-distance laying of collection pipe networks, low operating costs, good control of pathogens, and good water quality after sewage treatment, since the mid-1980s, Japan, South Korea, Australia Many countries, such as China and Europe, have also begun...
