Embodiment Construction

[0035] In order to better understand the present invention, the content of the present invention will be further clarified below in conjunction with the embodiments to reflect the functions of the present invention. However, the content of the present invention is not limited only to the following examples.

[0036] The present embodiment provides a natural ecological treatment process for domestic sewage, which comprises the following steps:

[0037] Step 1, primary treatment 1, adopts grid treatment and aeration and grit treatment; described grid treatment adopts drum-type fine grid 3 for processing, the grid width is 0.01m, and the grid gap width is 10mm. The water velocity in the front channel is 0.4m / s, the water depth in front of the grid is 0.3m, the grid inclination angle is 60°; the number of grid gaps is 28, and the diameter of the outlet pipe is 200mm. The aeration grit treatment uses an aeration grit chamber 4 with an aeration coil at the bottom, and the aeration ...

Abstract

The invention relates to a natural ecological treatment process for domestic sewage, which comprises the following steps of: 1, carrying out primary treatment, namely adopting grating treatment and aeration sand setting treatment; 2, carrying out natural ecological treatment, namely carrying out aeration treatment, microbial agent treatment and ecological treatment on a water body at the same time; and 3, carrying out buffer treatment on the sewage treated in the step 2 through an artificial wetland, and discharging the sewage. According to the natural ecological treatment process for domestic sewage, the sewage can be purified through the natural biological purification function and the comprehensive action of aquatic animals and plants, garbage and organic and inorganic pollutants in the domestic sewage are removed by fully utilizing the biological ecological action, and the ecological, environment-friendly and efficient effects are achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to natural biological treatment of domestic sewage, and more specifically to a natural biological treatment effluent process for domestic sewage pretreatment and secondary treatment. Background technique [0002] China's per capita water resources are small and the spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand gap for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, and it is in the same important position as the tap water production, water supply, drainage, and reclaimed water reuse industries. [0003] Although due to the increasing emphasis on environmental protection by the state and governments at all levels, China's sewage treatment industry is growing rapidly, the total amount of sewage treatment is increasing year by year, and the urban sewage...
