Embodiment 1

[0022] Example 1: Canna and hyacinth are planted in the swirl ditch of the ecological oxidation tower, reeds, calamus, etc. are mainly planted in the wetland, floating lotus, water turtle, sedge and cress are planted in the water-covered area in the center, and ornamental plants are planted at the end of the wetland. Woody plants; implementation effect: BOD 5 The removal rate is above 90%, SS removal rate is 89%, NH 3 The removal rate of -N is 70%, the removal rate of T-N is 84%, the removal rate of T-P is 87%, the removal rate of pesticides is 89%, the removal rate of virus is 94%, and the removal rate of total bacteria is 99%, reaching the national class II discharge water quality standards.

Embodiment 2

[0023] Embodiment two: in the swivel ditch of the ecological oxidation tower, plant canna, peppermint, chrysanthemum, hornwort, water hyacinth, reed, calamus etc. are mainly planted in the wetland, and the center is planted with water lilies, water turtles, and grass in the water-covered area, Ornamental woody plants are planted at the end of the wetland; implementation effect: BOD 5 The removal rate is above 92%, SS removal rate is 93%, NH 3 -N removal rate is 76%, T-N removal rate is 84%, T-P removal rate is 87%, pesticide removal rate is 89%, virus removal rate is 94%, total bacteria removal rate is 99%, reaching the national Class II discharge water quality standards.

Embodiment 3

[0024] Embodiment 3: plant calamus, water hyacinth, water chestnut, water onion, etc. in the swirl ditch of the ecological oxidation tower, reeds, calamus, etc. are mainly planted in the wetland, water lotus, water turtle, water chestnut are planted in the center covered by water, and the end of the wetland is planted Ornamental woody plants; implementation effect: BOD 5 The removal rate is above 90%, SS removal rate is 87%, NH 3 The -N removal rate is 73%, the T-N removal rate is 84%, the T-P removal rate is 90%, the pesticide removal rate is 89%, the virus removal rate is 94%, and the total bacteria removal rate is 99%, reaching the national class II discharge water quality standards.

Abstract

The invention relates to an ecological and oxidize composited process method for lift sewage. It includes following steps: 1) sewage flowing into interflow sewage canal by pipe, then it is send into sewage collecting tank by water pump at last end of interflow canal; 2) sewage inthe collecting tank is send into top filter tank on ecological oxidizing tower by constant-current pump after being filtered by separating grid; 3) sewage in filter tank flows down into rotary ditch in ecological oxidizing tower, which plant perennial hygrophutes in, passing through each layer utill to bottom rotary ditch; 4) sewage in bottom rotary ditch flows to nunja through water exit of ecological oxidizing tower; 5) sewage flows into natural river through nunja.

Description

technical field [0001] The invention relates to a domestic sewage treatment method in the environmental protection industry, in particular to a domestic sewage ecological and oxidation comprehensive treatment method. Background technique [0002] With the continuous development of society and the improvement of people's living standards, our country's annual domestic water consumption is increasing, which brings about an increase in domestic sewage discharge year by year. At present, there is already a relatively complete set of facilities for the treatment of urban domestic sewage, which is to establish an urban sewage treatment plant, and collect domestic sewage to the sewage treatment plant through the established sewage pipes for treatment. After reaching the discharge standards stipulated by the state , and then discharged. However, due to the influence of rural objective conditions, the agricultural sewage and domestic sewage produced in the vast rural areas have the ...
