Embodiment 1

[0034] Example 1, such as figure 1 Shown, the tower reactor of a kind of rural waste water ecological treatment described in the embodiment of the present invention, this tower reactor comprises:

[0035] Regulating pool 2, which communicates with anoxic reaction pool 5;

[0036] Sedimentation tank 8, which communicates with the anoxic reaction tank 5, and the upper part of the sedimentation tank 8 is provided with an overflow weir 7;

[0037] Falling water oxygenation step 15, which communicates with overflow weir 7;

[0038] Constructed wetland 21, which communicates with falling water oxygenation step 15.

[0039] The tower reactor of the present invention transports the rural sewage to be treated to the regulating pool 2 through the water inlet pipe 1, and the regulating pool 2 is used to adjust the water quantity and water quality of the sewage to meet the requirements of the subsequent treatment equipment for the sewage water quality. At the same time, it can also pro...

Embodiment 2

[0053] Example 2, such as figure 2 Shown, the present invention also provides a kind of rural waste water ecological processing method, and this method comprises the following steps:

[0054] Step 1, pretreating the water quality of rural sewage through the regulating pool 2;

[0055] Step 2, transporting the pretreated sewage to the anoxic reaction tank 5 for denitrification treatment;

[0056] Step 3, transporting the denitrified sewage to the sedimentation tank 8 for solid-liquid separation, and discharging the settled sludge;

[0057] Step 4, transporting the supernatant after solid-liquid separation to the constructed wetland 21 for ecological treatment.

[0058] Further, the pretreatment in step 1 includes one or more of water temperature adjustment, water volume adjustment, pH value adjustment and pre-aeration.

[0059] The sewage first enters the regulating tank 2 through the water inlet pipe 1 for pretreatment; then the pretreated sewage is transported to the anox...

Abstract

The invention discloses a tower reactor for ecologically treating rural wastewater, which comprises an adjusting tank communicated with an anoxic reaction tank; the sedimentation tank is communicatedwith the reaction tank, and an overflow weir is arranged at the upper part of the sedimentation tank; the hydraulic drop oxygenation step is communicated with the overflow weir; and the constructed wetland is communicated with the drop oxygenation step. The invention also provides a rural wastewater ecological treatment method. The method comprises the following steps: step 1, pretreating the water quality of rural sewage through the regulating tank; 2, conveying the pretreated sewage into an anoxic reaction tank, and carrying out denitrification treatment; 3, conveying the denitrified sewageinto a settling pond for solid-liquid separation, and discharging settled sludge through a sludge discharge pipe; and 4, conveying the supernatant subjected to solid-liquid separation into an artificial wetland, and carrying out ecological treatment on the supernatant through the comprehensive action of wetland filler and wetland plants.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a tower reactor and a treatment method for ecological treatment of rural wastewater. Background technique [0002] Fecal sewage mainly contains COD, NH3-N, TP and other substances, and contains pollutants such as bacteria, parasite eggs and infectious disease pathogens. If the manure is discharged directly into the water body without treatment, it will cause the water body to turn black and smelly, and the harmful gases with odorous molecules such as ammonia, hydrogen sulfide and sulfuric acid contained in it will lead to aggravated pollution. Studies have shown that 51% of COD, 91% of nitrogen, and 78% of phosphorus in domestic sewage come from fecal sewage. One ton of fecal sewage will pollute 220 tons of clean water, which is harmful to the environment and human health. cause serious impact. [0003] Due to the limitations of supporting living facilities in rural ar...
