Description

A kind of artificial swamp

Technical field

The utility model relates to a kind of artificial swamp.

Background technology

Artificial swamp is a kind of sewage disposal technology, by sewage, mud controlledly dosing on the artificial wetland built, sewage and mud are in the process flowed in a certain direction, mainly utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry, biological triple synergy, to a kind of technology that sewage, mud process.Its mechanism of action comprises absorption, delay, filtration, redox, precipitation, microbial decomposition, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of animal.It has that treatment effect is good, during-operation service convenient management, engineering capital construction and the feature such as running expense is low, is widely used in the area process sanitary sewage of land resources relative abundance, preserves the ecological environment.

Artificial wet land system is formed primarily of Wetlands ecosystems and water distribution system.Wherein Wetlands ecosystems are generally made up of the waterplant that bio-carrier and bio-carrier are cultivated and attached microbial; Water distribution system decides the operation scheme of artificial wet land system, is responsible for transporting sewage in Wetlands ecosystems.In sewage, the organic pollutant of the element such as carbon containing, nitrogen, phosphorus can be absorbed as the nutrition of plant in Wetlands ecosystems and microbial metabolism growth or be degraded; Oxygen needed for Wetlands ecosystems operation is also be transported to root system of plant and bio-carrier surface by water distribution system.

Current artificial wet land system is generally divided into horizontal flow, undercurrent and vertical current, and wherein, floor space is little compared with other form wetland, processing efficiency is high, whole system can be built inferior advantage completely in and be widely used because it has for vertical current constructed wetland.

Summary of the invention

The technical problems to be solved in the utility model, is to provide a kind of artificial swamp, its packing material size and reasonable structural arrangement, can prevents line clogging, and the filler water permeability of coarse sand and gravel mixing is good, and the efficiency of disposing of sewage is high.

The utility model realizes above-mentioned technical problem like this:

A kind of artificial swamp, described artificial swamp comprises a wetland pond, impervious barrier, layer of displacement, transition layer, filtering layer and tectum is disposed with from top to bottom at the bottom of the pond in described wetland pond, the pool wall in described wetland pond is also provided with impervious barrier, the conduit of plural number is embedded with in described layer of displacement, the sidewall of each conduit is evenly provided with plural number and collects slotted eye, described tectum is provided with plural water pipe, each described water pipe is provided with plural water hole; The gravel that described layer of displacement is 16 ~ 20mm by particle diameter forms, and the gravel that described transition layer is 8 ~ 16mm by particle diameter forms, and described filtering layer particle diameter is the mud coarse sand composition of 0.2 ~ 6mm, and described tectum is the gravel of 8 ~ 16mm by particle diameter.

Further, the thickness of described layer of displacement is 18 ~ 22cm, and the thickness of described transition layer is 8 ~ 12cm, and the thickness of described filtering layer is 75 ~ 85cm, and described tectal thickness is 8 ~ 12cm.

Further, the receiving tank bore dia that described conduit is arranged is less than the diameter of layer of displacement gravel, can prevent gravel blocking pipe.

Further, described impervious barrier is geotextile impervious barrier, and its cost is low, and installation process is simple, quick.

The utility model tool has the following advantages:

Each packing layer of the present utility model has following functions: impervious barrier, prevents sewage permeation polluted underground water body;

Layer of displacement, is collected filtration treatment sewage, and is discharged by conduit; Transition layer, for preventing the lower layer of displacement of the gravel blocking of upper level filter layer; Filtering layer, for filter sewage; Tectum, adopts particle diameter to be the gravel of 8 ~ 16mm, the less filtering layer of particle diameter can be avoided directly to be washed away by the sewage flowed out in hydraulic pipe, and the filtering layer unfairness caused affects filter effect.

The utility model is by the screening to each packing layer thickness of wetland and gravel particle diameter, solve existing artificial swamp because Study on Packing Medium Selection particle diameter is unreasonable, filling-material structure arrange unreasonable, pipeline tapping mode is unreasonable etc. and the line clogging problem that causes, greatly reduces the probability of line clogging; Artificial swamp of the present utility model is vertical flow pattern, without any need for sludge treatment device, sewage is diafiltration downward vertically from top layer, successively through different medium layers in defluent process, reach the object of purification, its to the aerobic organic processing power in waste water and nitrification ability stronger.

In a word, the utility model adopts gravel and coarse sand to form hypothallus, can provide good carrier for microorganism, for sewage seepage flow provides good hydraulics, there is provided the matrix needed for aquatic plants growth, the filler water permeability of coarse sand and gravel mixing is good, and the efficiency of disposing of sewage is high.
