Problems solved by technology

Although these studies reduce the land demand of constructed wetlands by improving the purification efficiency to a certain extent, they have not fundamentally solved the situation of constructed wetlands and people competing for land, thus limiting the application of this technology

Embodiment 1

[0018] The sewage collected from the sewage collection pipeline is introduced into the sedimentation tank on the right through the water inlet 1 set above the rear wall 7 of the sedimentation tank with a height of 1.5m--2m, and the sedimentation and separation are carried out, and the solid matter is deposited under the water inlet 1. The sediment collection area 8, the right side of the sediment collection area 8 is set as the bottom 6 of the sedimentation tank, the slope at the bottom of the sedimentation tank 6 is designed with a difference of 50-60 centimeters before and after, so that the solid sediment slides to the sediment collection area 8 automatically, The oil pollution baffle 4 is set 0.3m before the water outlet area on the left side of the sedimentation tank, and the oil pollution baffle 4 is built 50 cm above the bottom of the pool.

Embodiment 2

[0020] The height of the wall in the water outlet area is 1m-1.5m, and the water outlet 3 is set above the front wall 5 of the sedimentation tank, and the degraded and separated water is introduced from the water outlet 3 through the pipeline ( figure 2 ) The water distribution system 11 arranged on the left side of the artificial filter bed 14 enters the artificial filter bed 14 through the water distribution system 11, flows down the artificial filter bed 14 with a gradient of 5‰13, enters the collection system 12, and artificially filters The bed soil is composed of 1 / 3 river sand (particle size 1-2mm) + 1 / 3 limestone particles (particle size 1-2mm) + 1 / 3 soil. Inflow through the pipe ( image 3 ) The functional area of ​​the ecological pond is the inclined pond bottom 15 in the reed planting area, and the pollutants in the water are further degraded in this area, passing through the tall reed planting area 18.

Embodiment 3

[0022]The left side of the reed planting area 18 is provided with an inclined pool bottom 16 of the water lily lotus planting area, and the water lily lotus planting area 19 is the inclined pool bottom 16 above the water lily lotus planting area.

Abstract

The invention discloses a landscape type combined domestic sewage purification system, which is formed by a water inlet, a sewage disposal port, a water outlet, an oil stain baffle, a settling pond front wall, a settling pond bottom, a settling pond rear wall, a sediment collecting area, a water inlet end baffle of an artificial filter bed, a water outlet end baffle of the bed, a water distribution system, a collection system, the gradient of the artificial filter bed 0.5 percent, the artificial filter bed, an inclined pond bottom of a reed planting area, an inclined pond bottom of a water lily lotus planting area, a horizontal pond bottom of a submerged plant planting area, the reed planting area, the water lily lotus planting area and a pond planting submerged plant planting area. The purification system plays a certain role of protecting surrounding surface water; and since the purification of sewage can be realized by using a town landscape system, the invention also solves the problem of tense land occupied by domestic sewage. Since the purification of the sewage can be realized by adopting a natural process in large amount, the system has low operation cost and simple maintenance. The invention has the advantages of scientific and reasonable design, integration of afforestation and sewage disposal and guarantee of green land multifunction, green land water purification, green land sewage disposal and green land landscape.

Description

technical field [0001] The invention relates to a sewage purification system, in particular to a landscape-type combined domestic sewage purification system. Background technique [0002] With the improvement of people's living standards, sanitary facilities have been greatly popularized. The subsequent household sewage discharge has also increased sharply. At present, the ecological treatment technology of domestic sewage is developing rapidly, and the most representative one is the artificial wetland technology. This type of technology mainly relies on natural processes to remove pollutants in sewage to purify the water quality. It has low operating costs, convenient management, and good results, but it also has the problem of occupying a large area. There are also endless technologies based on the principle of constructed wetland technology, but more attention is paid to the development of matrix materials and the optimization of management technology. The main effect i...
