Abstract
The invention discloses an ecological-purifying ditch which integrates sewage transportation, purification and reuse and is formed by sequentially connecting four parts including a water-inlet area, purifying areas, water collecting and reusing wells and a water-outlet area. Sewage enters the water-inlet area of the purifying ditch and enters the multiple stages of purifying areas with gradually-lowered ditch-bottom height after uniform water distribution for multistage water-fall enhanced oxygenation, and each water collecting and reusing well is arranged between the adjacent stages of purifying areas. The purifying areas are configured with different graded-gravel fillers, plants are planted, the tail end of the ecological-purifying ditch is provided with the water-outlet area and a water-discharging pipe, and the processed sewage is discharged to a nearby water body. The ecological-purifying ditch is used for rural sewage transportation, the three functions of sewage transportation, processing and reuse are integrated, biological-materialized-plant cooperative purification and natural water-fall enhanced oxygenation technologies are adopted, and the ecological-purifying ditch has the advantages of high processing efficiency, low operating-energy consumption, less occupied land, convenience in management, flexibility in arrangement, good landscape effect and the like.
Description
Technical field
The invention belongs to sewage disposal, environmental protection technical field, be specifically related to a kind of channeltype ecological purification ditch.
Background technology
At present, along with constantly carrying out of China's new countryside construction, the problem that country sewage is handled also manifests gradually.Conventional municipal sewage treatment facility investment is big, working cost is high, operational management is complicated, is not suitable for country sewage and handles.In recent years, still be in the starting stage for the research of country sewage treatment process, disclosed technology is less.Successively disclosed 200920013004.8 " unit type membrane and biolytic country sewage treatment station ", 200910060176.5 " compound artificial wetland treatment process of domestic sewage in villages and towns in rural areas " and 200910236389.9 " alternative perpendicular flow artificial wetland rural sewage courtyard type landscape treating device " etc. of Chinese patent literature for example.Above-mentioned country sewage treatment technology needs mechanical means, and structure is complicated, and the investment working cost is also higher; And also there is the problem that floor space is big, reusing sewage is inconvenient in artificial wetland process.
Summary of the invention
Deficiency at existing country sewage treatment process existence, the purpose of this invention is to provide a kind of channeltype ecological purification ditch, this technology can collect sewage transport, purifies and be back to one, has that treatment process is simple, treatment efficiency is high, a less investment, low operating cost, the little and good landscape effect of occupation of land.
The technical scheme that the object of the invention realizes is as follows:
A kind of ecological purification irrigation canals and ditches that design at the water drain that country sewage is carried, described ecological purification irrigation canals and ditches front end and end are inhalant region and exhalant region, pick out water pipe in the exhalant region rear end.Series connection is provided with the stage purification district between inhalant region and exhalant region, and height reduces gradually at the bottom of the canal, is communicated with the cascading fall of water form.The reuse well that catchments is set between the purifying areas at different levels; Gravel filling and plant are set in each purifying area, and reduce the gravel particle diameter of purifying area along the ecological purification irrigation canals and ditches after by forward direction gradually; Be provided with partition wall in the purifying area, the perforate by partition wall top or bottom makes current form baffling up and down.
The water treatment procedure of this purification ditch is as follows:
Sewage is through after the pre-treatment, enter by water inlet pipe and to enter purifying area after purifying ditch inhalant region uniform water distribution, utilize biology-materialization-plant cooperated effect, by the pollutents such as suspended substance, organism, nitrogen and phosphorus in approach such as filtration, absorption, precipitation, microbiological deterioration and the plant absorbing removal waste water, be back to farmland on the way by being located at purifying area pump well along the line simultaneously, near the water body last water outlet discharging.
Compared with the prior art, the present invention has following characteristics:
1. collect sewage transport, purify and be back to one
This ecological purification ditch is a channeltype, can arrange along road or agricultural irrigated area, makes reusing sewage very convenient.In the process of sewage disposal, sewage is transferred purification along purifying ditch on the one hand, by the reuse well that catchments along the journey setting, is back to the farmland along journey easily on the other hand.
2. there is not the energy consumption operation
The ditch depth of this ecological purification irrigation canals and ditches is more shallow, utilizes atmospheric natural reaeration oxygenation in the drainage flow process on the one hand; On the other hand,, by ladder purifying area is set and makes full use of the physiographic relief drop reinforcement reoxygenation that drops, realize the no energy consumption of oxygenation process in the area that topographical elevation difference is arranged.
3. landscape effect is good
In ecological purification ditch purifying area plantation plant such as Canna generalis Bailey, cyperus alternifolius etc., not only strengthened wastewater purifying efficiency, the ecological purification ditch also can form good landscape effect construct the colored platform with landscape effect along journey.
4. lay flexible arrangement, worker's flow process brief, need not special-purposely to take up an area of, low, the convenient management of investment
This purification ditch can arrange that arrangement form is flexible, need not the shape that is in line along road or agricultural irrigated area; Its length, width and the degree of depth all can be regulated within the specific limits, can suit measures to local conditions according to the scene; Need not special-purpose wastewater treatment facility land used, do not take good farmland and forest land; Purifying ditch does not have working cost, manages very conveniently, does not need professional's management maintenance.
5. surplus sludge volume is few
This purification ditch mainly utilizes the pollutent in physics, chemistry, biology and the plant purification effect removal water, and sludge yield is low.
In sum, this ecological purification recycling ditch collection sewage transport, purify and be back to one, adopt the channeltype decoration form, can not only make full use of the landform drop oxygenation, also made things convenient for sewage along Cheng Huiyong, realized the no energy consumption and the reuse of scavenging process by what purify the ditch reuse well that catchments along the line.In addition, this facility has good landscape effect, and need not special-purpose land used, invests advantages such as low, convenient management, and popularizing application prospect is good in the rural area.

Embodiment
Referring to Fig. 1 and Fig. 2, the ecological purification irrigation canals and ditches comprise water inlet pipe 1, inhalant region 2, purifying area 3, the reuse well 4 that catchments, exhalant region 5 and rising pipe 6.Ecological purification irrigation canals and ditches front end and end are inhalant region 2 and exhalant region 5, and series connection is provided with stage purification district 3 between inhalant region 2 and exhalant region 5, and height reduces gradually at the bottom of the canal, is communicated with the cascading fall of water form.The reuse well 4 that catchments is set between the purifying area.At each purifying area gravel filling and plant are set, and reduce the gravel particle diameter of purifying area along the ecological purification irrigation canals and ditches after by forward direction gradually.Also be provided with partition wall at purifying area 3, and, make current form baffling up and down in the perforate of the top or the bottom of partition wall.The end of ecological ditch picks out pool 5, connects near water body of sewage discharge or reuse farmland after rising pipe 6 will be handled.
