Embodiment Construction

[0017] The artificial wetland domestic sewage treatment method of the present embodiment comprises the following steps:

[0018] 1) see figure 1 ,See Figure 4 , fill the pool body 12 with anti-seepage layer 13 on the bottom and surroundings, fill sand 4 and plant plants 5, the sewage enters from the water inlet 1, passes through the water distributor 1B, and most of the sewage 1a enters through the water inlet check valve 1A The pool body is infiltrated upwards, so that the plant root system 5.1, the sandy soil 4 and the sewage form a sandbar ecological device containing biofilm, and the sewage is purified through the biofilm.

[0019] 2) see Figure 4 , another part of the sewage 1b through the water distributor 1B is passed into the L-shaped water pipe 2, and the hard shell 3 formed by the biofilm is automatically watered to soften and sink. And along the inclined bottom surface 14, the floating sediment 9.2 is made to flow along the slope and be at the lowest position b...

Abstract

An artificial wetland sewage processing method and system belongs to processing of sewage and sludge, can solve problems of present artificial wetland biological film obstruction and short life. Excavating a pool body which filling with sandy soil and planting plant, an influent non-return valve is arranged under the pool body, sewage enters the pool body via the valve and permeates upward, a shoalbank ecosystem containing a biological film is composed of a root system, sandy soil and sewage, which purifies sewage through the biological film. A hard shell formed by the biological film is poured automatically, softened and sank by a L pipe, goes together with sewage scum through an erected scum pipe and a scum non-return valve in thereof, scum is sucked out by pressure difference generatedby machinery or manmade. The non-return valve is automatically opened / closed by overflow of the L pipe. The L pipe also can conveniently provide fecal sewage for peasant to water farmland. In order toprevent generating thick biogas in the shoalbank ecosystem to cause explosion, a silo and a movable cover are arranged, people may enter and detect to guarantee safe operation. The invention is fit for domestic sewage treatment.

Description

[0001] (1) Technical field: The artificial wetland domestic sewage treatment method and device of the present invention belong to the treatment category of sewage and sludge (C02F). (two) background technology: [0002] Constructed wetlands include subsurface sewage ecological treatment technology. Sand bars are formed by plants planted above, sand in the wetland and sewage. Sewage flows in from the bottom of the wetland. During the flow, biofilm is formed through sewage, sand and plant roots. Realize the purification of sewage. However, it is often blocked by the hard shell formed by biofilm, making it impossible to purify the sewage, resulting in an extremely short lifespan of the constructed wetland. (3) Contents of the invention: [0003] The artificial wetland domestic sewage treatment method and device proposed by the present invention solve the problems of existing artificial wetland biofilm clogging and short service life. Its technical scheme is as follows: [000...
