Abstract

The invention relates to the field of a sewage treatment system, particularly a no-discharge sewage treatment system which has the advantages of high cleanness, environmental protection and low operating cost. The no-discharge sewage treatment system comprises a pretreatment device, a precise water filtration device and a soil purification device, wherein the pretreatment device comprises a corrosion chamber and a pre-filtration chamber; the pre-filtration chamber is provided with a feed port and a discharge port; the corrosion chamber is communicated with the feed port of the pre-filtration chamber; the pre-filtration chamber is filled with a filter material; the precise water filtration device comprises a water covering tank and a water collection pipe; the water covering tank is provided with a water inlet and a water outlet; the water inlet is communicated with the discharge port of the pre-filtration chamber; the water collection pipe is provided with a water outlet section, designed in a groove structure, and communicated with the water outlet; the soil purification device comprises a soil filtration component and a water distribution fabric; the soil filtration component is composed of air-permeable soil, including volcanic rock ash and / or steelmaking furnace slag; the soil filtration component is arranged on the upper side of the water collection pipe; and one end of the water distribution fabric is arranged in the water covering tank, and the other end is arranged in the soil filtration component.

Description

technical field [0001] The invention relates to the field of sewage systems, in particular to a non-discharge sewage treatment system. Background technique [0002] There are three types of sewage treatment methods that are widely used at present: [0003] ①Mechanical aerobic sewage treatment system, which is characterized by the use of mechanical devices for aerobic treatment of sewage, and the disinfection of sewage by way of dosing. The system requires the use of mechanical equipment such as fans, water pumps, and automatic drug delivery devices. [0004] ② In the vast rural towns and other areas without urban public sewage pipe network and treatment system, the second or third format septic tanks are used. This treatment method is only to do primary biological decomposition of sewage, and regularly pump the sewage in the pool to the designated sewage treatment place for advanced treatment by special vehicles. [0005] ③Seepage well is a kind of sewage discharge method...
