Description
Technical field
The present invention relates to a kind of natural reaeration/sedimentation integrated device, can be used for pre-treatment small-sized, distributing is dirty (giving up) water, be particularly suitable for the pre-treatment of samll cities and towns and Rural areas distributing, miniaturization sanitary sewage.The technical field that belongs to dirty (giving up) water treatment.
Background technology
At present, both at home and abroad at the processing of distributing, miniaturization dirt (giving up) water mainly based on biological treatment (as artificial swamp etc.), for complement lysis oxygen in biological treatment system (as artificial swamp etc.), improve processing efficiency, particularly strengthen the nitrated and denitrification effect of ammonia nitrogen, the enhanced aeration pre-treatment by aerobic section often will increase power consumption and running cost so greatly to achieve the above object.On the other hand, as sewage disposal technologies such as artificial swamps, often, technology can't normally be moved because of the long-term accumulation of suspended substance causes obstruction behind certain running life.For this reason, the present invention provides a kind of and can carry out natural reaeration from basic point energy-saving and cost-reducing and operation steady in a long-term, can carry out the isolating integrated pretreatment unit of suspended substance sedimentation again.
At present, the domestic patent that also has at reaeration/sedimentation integrated treatment unit, as: the dispersive high-efficiency purification treatment equipment of sewage of applications such as the oxygen-enriched reflux sedimentation tank of Shanghai Municipal Engineering Design Research Institute application in 2008 and Kunming University of Science and Technology in 2009.Though above-mentioned stream oriented device is a reaeration/sedimentation integrated device, all is provided with the aeration facility, still can not break away from problems such as increasing extra power facility and energy consumption, not only complex structure also makes energy consumption and running cost increase greatly.And natural reaeration/sedimentation integrated device of the present invention ties up to and breaks through on " natural reaeration " and natural reaeration and the efficient sedimentary coupled relation, still do not have similar report at present.
Summary of the invention
Technical problem: the invention provides a kind of with the energy efficiency be target be used for the sewage pretreatment natural reaeration/sedimentation integrated device, this device is suitable for the pre-treatment of the sanitary sewage of different areas, particularly samll cities and towns and Rural areas distributing, miniaturization sanitary sewage disposal engineering, operating performance is stable.
Technology contents: a kind of sewage pretreatment natural reaeration/sedimentation integrated device that is used for of the present invention, this device comprise housing and are positioned at the intravital water inlet pipe of shell, three grades of natural reaeration districts, sloping plate deposition district, water outlet collecting region, rising pipe; Water inlet pipe is positioned at the top of housing, rising pipe is positioned at the middle part of housing, the water outlet of water inlet pipe is connected by water sprayer and the distribution pipe that water mushroom shower nozzle is housed, waved plate is positioned at the bottom of water sprayer and water mushroom shower nozzle, the sloping plate deposition district is positioned at the bottom of waved plate, and the water outlet of water mushroom shower nozzle spray splashes into multistage staggered stacked waved plate, falls into the sloping plate deposition district at last, supernatant liquor through precipitate and separate enters the water outlet collecting region through the run by gravity connection, flows out integrated apparatus by rising pipe 5.
Beneficial effect: compared with prior art, the present invention has following advantage:
In order effectively to solve the power consumption problem of treatment process in the past, the present invention utilizes the residue lift of water pump, adopt combined natural reaeration equipment, water sprayer, water mushroom spray equipment and multistage staggered stacked waved plate are carried out the natural reaeration district of series combination as integrated apparatus, remove most suspended substances and partial organic substances by swash plate (or inclined tube) settling region.Integrated apparatus need not additionaling power consumption, has reduced the running cost of system.
This device is a kind of natural reaeration and dirt (giving up) water pre-treatment means that is deposited in one of collecting, has energy-saving and cost-reducing, as to reduce system operation cost advantage, can effectively reduce of the harm of the entrained pollutent of sanitary sewage, also can be subsequent biological treatment or advanced treatment (as artificial swamp etc.) and create conditions water body.Simultaneously, also have characteristics such as simple in structure, that engineering cost is cheap, running maintenance is easy.Be suitable for the pre-treatment of the sanitary sewage of different areas, particularly samll cities and towns and Rural areas distributing, miniaturization sanitary sewage disposal engineering, operating performance is stable.
