Problems solved by technology

At the same time, since most of the townships in the reservoir area are economically underdeveloped areas, soil and other infiltration media that are common in the reservoir area and have good infiltration performance should be selected, and scientific, reasonable and simple construction methods should be adopted, with less human intervention. In the case of basically maintaining the "natural" growth s

Abstract

The invention relates to a manual soil bed quick-seepage sewage treatment system. The bottom plate of a quick-seepage pool is provided with an anti-seepage layer; a bearing layer is arranged on the anti-seepage layer; and a seepage and drain pipe is arranged between the anti-seepage layer and the bearing layer and is used for absorbing water; and water is discharged from a water outlet weir through a height-adjustable weir plate. The bearing layer is composed of a lower pebble layer and an upper haydite layer. The upper part of the bearing layer is a treatment layer, and the treatment layer is a mixed layer composed of soil and river sand. Plants are grown on the surface of the treatment layer, and the surface of the quick-seepage pool is provided with a water distribution system. The invention has the characteristics of strengthened reoxygenation effect, high removal rate of ammonia nitrogen, good outlet water quality, low investment, low energy consumption, simple and convenient operational management and the like. The system is especially suitable for soil and climatic conditions in mountain areas and hill towns (such as towns in the Three Gorges reservoir region).

Description

technical field The invention relates to a sewage treatment system, in particular to an improved artificial soil bed quick-seepage sewage treatment system, which is especially suitable for domestic sewage treatment or micro-polluted water restoration in small towns in mountainous areas and hills, and belongs to the field of environmental protection water treatment. Background technique Artificial soil bed quick-seepage sewage treatment process is a kind of water quality purification technology based on natural ecological principle, and its investment and operation cost are 1 / 3-1 / 2 of conventional water treatment technology, and purification effect is better, both can Instead of conventional processing, it can also be used as an advanced processing technology for conventional processing. Since the 1990s, my country's township sewage treatment has increasingly adopted this technology. At present, the traditional artificial rapid infiltration system has disadvantages such a...
