Description

A kind of comprehensive artificial swamp filler sewage ecological treatment system

One, affiliated technical field

The utility model relates to a kind of Sewage treatment systems, a kind of specifically a kind of comprehensive artificial swamp filler sewage ecological treatment system that can be widely used in domestic sewage in rural areas by using processing, the municipal wastewater processing of middle samll cities and towns and the improvement of urban water system Sewage outlet.

Two, background technology

How present known sewage disposal measure is by artificial sudden and violent gas, the mode that adds chemical agent makes sewage obtain handling up to standard, perhaps adopt traditional Anaerobic Microbiological Treatment Technology that sewage is handled, their shortcoming is the mass consumption energy, can produce a large amount of mud in the treating processes and cause secondary pollution, front-end investment is big, the working cost height, the management expectancy height, processing mode is not ecological, need a large amount of municipal pipelines to match, these shortcomings cause small and medium-sized cities and rural area can not to build sewage work, also make the small city with not rising even built the working cost of sewage work's great number, the rural area has difficulties especially.So these sewage disposal modes are the particularly small and medium-sized cities and the rural area incompatibility of poverty-stricken area in small and medium-sized cities and rural area.Incity, city water system has a lot of sewage draining exits to be difficult to realize the sewage disposal purpose with above technology simultaneously.Because the filler problem causes sewage treating efficiency low, the efficient of especially disposing of sewage winter can be lower again for existing artificial swamp technology, is difficult to realize a large amount of processing of sewage, goes out water unstable simultaneously and be difficult to reach standard-required, therefore can not be used widely.Developed a kind of comprehensive artificial swamp filler sewage ecological treatment system at above situation.

Three, summary of the invention

This uses novel purpose to provide a kind of comprehensive artificial swamp filler sewage ecological treatment system, has solved energy-conservation, Winter protection, secondary pollution, operation complicated problems.

This use is novel by such realization: comprise impervious barrier (1), porous header (2), gravel bed (3), the lime-ash and the peat composed of rotten mosses mixing bed of material (4), the polyethylene particulate material and the peat composed of rotten mosses mixing bed of material (5), peat composed of rotten mosses layer (6), porous water distributor (7), root system of plant (8), waterplant (9), wetland water-in (10), wetland effluent mouth (11), gas exhaust duct (12), wetland regulation of level well (13), regulate aboveground have system's water outlet (14) and flexible pipe (15), system's settling tank (16), around reaching, this bottom of device is covered with impervious barrier (1), lay porous header (2) on impervious barrier (1) bottom in order to collect the water of treated mistake, porous header (2) is laid gravel bed (3) on every side, porous header (2) is connected with gas exhaust duct (12), gravel bed (3) is gone up and is laid the lime-ash and the peat composed of rotten mosses mixing bed of material (4), the lime-ash and the peat composed of rotten mosses mixing bed of material (4) are gone up and are laid the polyethylene particulate material and the peat composed of rotten mosses mixing bed of material (5), the polyethylene particulate material and the peat composed of rotten mosses mixing bed of material (5) are gone up and are laid peat composed of rotten mosses layer (6), the lime-ash and the peat composed of rotten mosses mixing bed of material (4), the polyethylene particulate material and the peat composed of rotten mosses mixing bed of material (5), root system of plant (8) is arranged in the peat composed of rotten mosses layer (6), lay porous water distributor (7) in the peat composed of rotten mosses layer (6), peat composed of rotten mosses layer (6) is gone up to plant hygrophyte (9), impervious barrier (1) bottom has wetland effluent mouth (11) to be connected with wetland regulation of level well (13), and impervious barrier (1) top has wetland water-in (10) to link to each other with porous water distributor (7).Flexible pipe (15) on the wetland regulation of level well (13) can be regulated the water outlet water level of wetland regulation of level well (13), and then adjusting wetland water level, system's water outlet (14) of wetland adjusting well (13) leads to the settling tank (16) of system, and the water of system's settling tank (16) can be used as agricultural irrigation water or greenery patches water through final post precipitation.

Winter, then polyethylene particulate material and the peat composed of rotten mosses mixing bed of material (5), peat composed of rotten mosses layer (6) can effectively play the insulation effect to system, the ice up in winter phase can promote the wetland water level by wetland regulation of level well (13) simultaneously, form an ice sheet on peat composed of rotten mosses layer (6) top and play insulation effect, improved the operational efficiency of system in winter system.

Four, this uses novel beneficial effect

This use is novel can be to the city municipal wastewater, domestic sewage in rural areas by using, the sewage that the urban water system Sewage outlet is discharged is efficiently handled, sewage after the processing can directly serve as the water source, greenery patches and without secondary treatment, be both energy-conservation, the novel method of water saving, therefore novel too many equipment and the structures of not needing of this use simultaneously invest saving obviously, in operational process, manpower are saved in the not too many requirement of management simultaneously, aspect operation, should use and novelly can obviously reduce running cost, ton water running expense can realize the sewage disposal zero cost below 0.2 yuan on the ground that physical features is arranged.Therefore this use is novel is a kind of novel process that rises that plays again usefulness of promptly building.This use is novel also solved winter operation insulation problem polyethylene foam beads material and the peat composed of rotten mosses the mixings bed of material (5), peat composed of rotten mosses layer (6) thus can effectively play insulation effect assurance effluent quality in winter, this use is novel not only also also to have obvious removal effect to N, P to the guaranteed while of conventional pollutant removal.This uses novel sewage closed operation therefore not have stink, does not grow mosquitos and flies, and the plant-growth on the wetland has also increased local greenery area has comprehensive improved effect to environment.
