Abstract

The invention discloses a sewage management process capable of treating and recycling point source sewage. The process can treat the sewage which cannot be brought into a municipal pipe network, and the treated water can be used as regenerated water and collected by a biological pool for recycling. The process has great popularization value on management of the point source sewage, in particular management of the sewage which cannot be brought into the municipal pipe network in new village construction matched sewage treatment facilities, remote reservoirs, scenic spots and the like.

Description

Natural power point source saprobia ecological management and reuse technology
(1) technical field:
A kind of processing and the technology of reuse that the present invention relates to point source sewage, the pollution load that particularly requires to reach the higher emissions standard is not high, the improvement of can biochemical degree higher sanitary sewage.
(2) background technology:
Because pipe network is laid and current conditions is limit, the sanitary sewage of a lot of rural areas, tourist attractions can't be included city planting ductwork in, and these sewage have constituted huge threat to the environment and the phreatic water quality safety of locality.The improvement technology of point source sewage mainly comprises at present: activated sludge process, biomembrance process, natural facture, MBR and anaerobism technology, the independent use of these methods has the following disadvantages: 1, the cost of investment of activated sludge process, biomembrance process and MBR and operation management expense are higher, the maintenance personnel who needs specialty, at the less point source sewage disposal of the water yield, the too low and management inconvenience of cost performance; 2, use the water outlet effect of nature facture or anaerobic treatment relatively poor separately, can not reach the purpose of direct reuse; 3, owing to characteristics such as point source sewage exist the dirty mixed flow of rain, Pollutant levels are on the low side, conventional biologic treating technique starts and the steady running difficulty.
(3) summary of the invention:
The objective of the invention is to disclose a kind of biological and ecological processing of point source sewage and the technology of reuse, can't include the geographic point source waste water control of city planting ductwork problem in, improve the human settlement, simultaneously, the reuse water after handling is collected reuse, conserve water resource to solve.
Technical solution of the present invention is:
A kind of biological and ecological of point source sewage is handled the also technology of reuse, comprise the compound sewage treatment system that natural power sewage biological treating pond, artificial current wetland and biological pond composition biological and ecological combine, system's water outlet can be used as reuse water and does irrigation or view usefulness.
Sewage is collected after grid filtration imports water collecting basin with the supernatant liquor of septic tank after falling macrobead rubbish through pipe network, sewage is handled through the main reaction region that water inlet pipe enters the natural power sewage biological treating pond under action of gravity in the water collecting basin, sewage is by the effect of natural power sewage biological treating pond, can remove majority of organic pollutants and suspended substance, cut down pollution load.After the anaerobism intensive treatment, sewage flows under the influence of gravity into artificial subsurface flow wetland system further purifying treatment under the effect of Wetlands ecosystems equally.After artificial current wetland processing, water outlet can reach " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level A emission standard, the water outlet of artificial current wetland enters biological pond under action of gravity, the reuse water of collecting through biological pond can be used as irrigation or view purposes.
The natural power sewage biological treating pond comprises the grid regulatory region in the described technology, anaerobic zone, contact-oxidation pool and sand filtration district.In opening, establishes by grid fine fack, grid spacing 3~5mm.In anaerobic zone and the catalytic oxidation district soft-filler is arranged.Sand filtration has filtrate in the district, and filtrate is made up of sand and gravel.
Artificial current wetland comprises water distribution system, matrix fill bed, water exhaust system, muskeg etc. in the described technology.Water distribution system is a PVC perforated pipe water distribution.The bed of packings filler is by gravel, coarse sand, wood chip and soil constitution.Water exhaust system is that the PVC perforated pipe that is arranged on wet land filler bed bottom is collected the back draining.The vegetation on wetland surface is Chinese littleleaf box, Chinese rose, Canna generalis Bailey etc.
Biological pond is by the discarded pond of locality or river course reconstruction in the described technology, and reconstructional measures mainly comprises: prepartion of land, establish embankment, antiseepage, water plant planting.The waterplant of being planted comprises cattail, reed, Rush etc.
The invention has the beneficial effects as follows: utilization natural power sewage biological treating pond and artificial current wetland, the ecological measure of the biological pond improvement of carrying out point source sewage that combines not only can be administered point source sewage, make sewage reach higher emission standard, simultaneously, sewage after the processing can be used as irrigation water after biological pond is collected, can alleviate the problem of short water supply to a certain extent for the area of shortage of water resources.Because this technology does not need to consume maintenance measures such as any electric power, medicament, therefore, this technology has been saved manpower and materials without any operation cost.The improvement of point source sewage and the construction of biological pond are for improving surrounding enviroment and regulating miniclimate and play certain beneficial effect.

(5) embodiment
The present invention is a kind of a kind of processing and reuse technology of point source sewage, and embodiment is as follows:
(1) natural power sewage biological is handled
The natural power sewage biological treating pond is a glass reinforced plastic tank body reactor customized, and reactor is divided into the grid regulatory region, anaerobic zone, contact reacts district and sand filtration district.Soft-filler is installed in anaerobic zone and the catalytic oxidation district.Sand filtration district filler sand and gravel.Wherein lower floor is the gravel bed of thick about 10cm-30cm, and top is the layer of sand of thick about 80-150cm; Wherein lay PVC perforation header in the gravel bed.Sewage enters from the anaerobic zone bottom, and from the bottom to top successively by anaerobic zone filler and aerobic zone filler, the aerobic zone water outlet is from top to bottom by the sand filtration district, and the perforation collection tube that enters bottom, sand filtration district is discharged.
Through the processing of this system, the most of organism in the sewage is removed, and has cut down the pollution load of sewage.
(2) artificial current wetland Ecological Disposal
Sewage enters into artificial subsurface flow wetland system under action of gravity after the natural power sewage biological treating pond is handled, PVC perforation header is laid in artificial subsurface flow wetland system bottom, and matrix fill bed, wetland plant and PVC perforation rising pipe etc. are arranged in the wetland.
Through the processing again of this system, water outlet can reach " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level A emission standard.
(3) biological pond is collected reuse
The reuse water that is drained into biological pond after artificial current wetland is handled can be used as irrigates or landscape water is carried out reuse, and biological pond is handled through antiseepage, and has planted waterplant, helps water body to carry out natural purification.
