Description
Technical field
The utility model relates to a kind of biological air floatation method and system and device thereof that is used for community closed water landscape water system purification of water quality, belongs to water technology and water resources recycle utilization field.
Background technology
Sub-district view water system has characteristics such as water surface area is relatively little, water environment capacity is little, water body self-purification ability is low usually.Especially seal and mobile poor unhurried current water body, climate change, mankind's activity and surrounding enviroment all can pollute it, cause water quality deterioration, are embodied in that transparency is low, water body is muddy, wawter bloom is spread unchecked, even it is smelly to turn black, and therefore must carry out the purification treatment of view water system.Make a general survey of domestic and international view water system process technologies shape, can be divided into physics method, chemical method and biology/ecological method three major types in the view water system improvement technology of using or entered the pilot scale stage.
Physical method mainly contains bed mud dredging, machinery except that silt is dashed in algae, artificial oxygenation, diversion, water etc. is changed in diversion.
The bed mud dredging mainly is to improve at the high water body of bed mud nutrition content, but in excavating depth, prevents that the control of aspect such as titanium pigment and the release of ammonia nitrogen secondary in the deep layer bed mud is difficult.It is that the mistake Sheng algae in the water body is removed that machinery removes algae, though effective in short-term, often cure the symptoms, not the disease.Artificial oxygenation is the aeration aerating that relies on water, can only the local dissolved oxygen content that improves in the water body, and be difficult to guarantee the aerobic environment of whole water body.The diversion dirt removal comes down to the dilution diffusion to water pollutant and planktonic algae, and is real in pollution transportation, substantial improvement do not carried out in pollution at all.Water is changed in diversion then must the competent clean water source card of going bail for.
Chemical process comprises that mainly the adding chemical agent kills the precipitation of algae, adding molysite promotion phosphorus, adds lime denitrogenation etc.Characteristics such as chemical process has less investment, and Operation and maintenance are convenient, and are effective at different pollutents in the water, need add corresponding medicament and realize, but must take the secondary pollution of chemicals to the hydrobiological toxicity and the ecosystem into account.Therefore, the application of chemical method has significant limitation, generally uses as jury.
Biology/ecological method recovery technique principle is to utilize the vital movement of the biological or cultivation of cultivating, the microorganism that inoculates, to water pollutant shift, conversion and Degradation, thereby water body is restored, and this technology is a kind of reinforcement to nature restorability and self-purification capacity.But it is harsh that this method requires biomembranous cultivation domestication, the program complexity, the treatment time is long, artificial swamp treatment technology especially, floor space is big and be subjected to weather effect big, especially at water body than hour playing a role.
A kind of in recent years physico-chemical process that is normally used in the past to water treatment---air supporting method, because separation efficiency height, and have the effect of oxygenic aeration in water concurrently, begin the former water that is widely used in handling low temperature, low turbid, high algae, high luminance relay and is subjected to Organic pollutants.Show all that about studying and using remove and separate inorganic and organic suspension beyond the region of objective existence, the air supporting method also has certain removal effect for dissolved organic matter in the water.Because that the view water system is rendered as usually that algae amount is many as containing, look is heavily distinguished the flavor of is smelly, water quality is followed water quality characteristics such as seasonal variation, increase to a certain degree the intractability of coagulation-precipitation-filtration process.Therefore, air-float technology is introduced in the landscape water treatment technology, can be given full play to the air supporting method and precipitator method characteristics separately, and obtain treatment effect preferably.But, the subject matter of air supporting method existence at present is: no matter adopt traditional air supporting or shallow air-floatation, still need dosing coagulant owing to enter the former water of air flotation pool, just inevitably bring secondary pollution---problems such as the treatment and disposal of chemical body refuse, any coagulating agent adds the suspension pollutent that all can only remove in the sewage and few part dissolved organic matter in addition, for the basic reason that causes water pollution---nitrogen, phosphorus problem, then can't effectively remove.
In sum, make a general survey of various landscape water treatment technologies, no matter adopt which kind of single view treatment technology, there is problem more or less respectively at aspects such as economy, energy consumption, timeliness or secondary pollution controls, particularly the chief culprit who causes the body eutrophication problem---aspect the removal of nitrogen and phosphorus and dissolubility pollutant, there are not a cover economical, practical approach or system reliably so far.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model proposes a kind of community closed middle water landscape water system organism gas float treatment unit, purpose is to provide a kind of economical and efficient free of contamination new technology for the purification of water quality of middle water landscape water system.By making up a kind of like this treatment process and system and device thereof that combines biological and air flotation technology advantage of organism gas float, realize community closed in the purification of water quality of water landscape water system, solve current view water system treatment process the nitrogen that can't effect a radical cure and the problem of phosphorus and dissolubility pollutant.
Water landscape water system organism gas float biological air floatation method in community closed is characterized in: the former water in the landscape water body is sinked the scum silica frost mixing zone of biological reaction tank earlier by intake pump, and former water enters the catalytic oxidation district after the scum silica frost with the backflow of organism gas float pond mixes; The air in catalytic oxidation district is provided by roots blower, the muddy water mixed solution in catalytic oxidation district flows in the organism gas float pool device through water inlet pipe, the dissolved air water that the organism gas float pool device provides by air dissolved pump is realized separating of system's water outlet and active bio flco, the scum silica frost of its generation is back to the scum silica frost mixing zone of biological reaction tank after handle in the organism gas float pond, proceeds biological respinse with the former water in the landscape water body; Most of water outlet behind its separating clarifying is recycled into middle water landscape water system by going out water pump after the uv steriliser sterilization, and the small portion water outlet is used to provide dissolved air water by air dissolved pump.
The scum silica frost mixing zone is the amphimicrobian environment, and its dissolved oxygen (DO) remains on below the 0.2mg/L, and hydraulic detention time is about 15min; The catalytic oxidation district is an aerobic environment, and its DO remains on 3～4mg/L, and hydraulic detention time is about 45min.
