Problems solved by technology

The defect of these existing technologies is that the water after treatment is not recycled, which causes the waste of water resources and the pollution of the receiving sewage water body, and increases the economic burden of sewage discharge or reclaimed water treatment for residents, and also produces harm to people during the treatment process. Harmful odor, affecting the quality of the air environment

Embodiment Construction

[0019] refer to figure 1 Shown technological process, the main treatment process that embodiment 1 comprises is:

[0020] (a) aerobic biological treatment; and

[0021] (b) Wetland treatment.

[0022] The raw sewage generated by the residents in the residential area is discharged through the sewage pipe network, and is pumped into the primary sedimentation tank through the sewage pump room for preliminary sedimentation, and then enters the biological aeration tank for aerobic biological treatment, and the treated water undergoes secondary sedimentation in the secondary sedimentation tank , and then enter the wetland for wetland treatment. After the treatment, it can be used as recyclable water, which can be injected into the recycling facility through the water purification pump room for use, or discharged. The recycled water can enter the wetland again for treatment, forming a wetland for treatment to purify water. Then to the cycle of wetland treatment, the sludge generate...

Abstract

The ecological treating process of waste water in wet land includes initial aerobe treatment and depth treatment in wet land. The aerobe treatment apparatus includes sealed aeration biological filtering tank, initial precipitating tank before the filtering tank and secondary precipitating tank behind the filtering tank. The initial treated waater flows via weir board to the wet land and the water after being treated in wet land may be reused. The present invention has low water treating cost and saving in water resource. The water treatment process produces no harmful gas and the wet land is also green landscape for residential area.

Description

Technical field [0001] The invention relates to an ecological treatment method for sewage wetlands in residential quarters. Background technique [0002] The treatment of sewage in residential areas generally adopts biological methods. The existing technology includes a combination of aerobic and anaerobic biological treatment processes with different process parameters. Among them, anoxic decomposition followed by aeration treatment is the most common process combination. one. The defect of these existing technologies is that the water after treatment is not recycled, which causes the waste of water resources and the pollution of the receiving sewage water body, and increases the economic burden of sewage discharge or reclaimed water treatment for residents, and also produces harm to people during the treatment process. Harmful odor affects the quality of air environment. Contents of the invention [0003] In order to overcome the defects of the prior art, the present i...
