Description
Affiliated technical field
The present invention relates to a kind of wastewater from hotel and handle and the energy-conservation little oxygen biological treatment combined process system of the odorless of reuse, belong to sewage treatment process.
Background technology
Hotel sewage mainly contains following several according to its source:
(1) kitchen waste water: contain organism, solid impurity, fat content height.
(2) toilet, guest room sewage: flushing closet sewage and washing wastewater, mainly contain organism, solid impurity, bacterium, washing composition and soap lye.
(3) waste water that gives the car a wash: mainly be solid impurity, petroleum-type grease.
(4) waste water of boiler house discharging: boiler effluent sewerage and softening regeneration waste liquid mainly contain salt in the water.
(5) air-conditioning cooling waste water: be mainly thermal pollution.
(6) the filter tank flushing waste water of natatorium or bath center recirculated water and swimming pool blowdown water.
(7) laundry drains: mainly contain surfactant, phosphorus.
(8) for the landscape style that contains water scenery, views and admires fish pond etc. the hotel of spending a holiday, also have water scenery recirculated water.
At present, wastewater from hotel generally adopts biochemical process.Blodisc is as the principal facility of biological treatment, and is stable, convenient management, and noise is little, and working cost is low, anti-shock loading, sludge yield is few, and use in the hotel that is fit to the medium and small water yield.The BOD of blodisc system
5The area load is 16.7gBOD
5/ (m
2D), HRT is 1h, and along with the corresponding adjustment rotary speed of the variation of hydraulic load, rotating disk exit dosing coagulant PAC5～10mg/L, chlorination 45min duration of contact.Can guarantee final outflow water water quality fully with the sand filtration filtration again after adopting the level Four blodisc, but should note the in time clear of grease removal tank washed in a pan
The single pond intermittent operation of SBR technology, the concentration of substrate height is followed aerobic, anoxic, anaerobic biochemical reaction process, the effective nitrogen phosphorus in kitchen, place to go and the using sewage of wash house, anti-shock loading is strong.Inquire into as a kind of technology,, handle Shangri-La Hotel, Harbin waste water two SBR pond series connection, suitable substantially for the clearance of pollutent in the sewage, but the fluctuation of two-part SBR effluent quality is littler, and water quality is also a little better.Two sections SBR methods are handled hotel sewage, most of (about 60%) organism is got rid of at first section, this part organism is for a long time abundant oxygenolysis of experience not, saved required aeration rate energy consumption and the reaction times of bio-oxidation, clearance is mainly caught with the absorption degradation effect by biofloculation, efficient absorption, precipitation net and is realized, the organism that is adsorbed can be removed by mud discharging, makes some hard-degraded substances also can get rid of by mud.
DAT-IAT technology is the improvement technology of SBR technology, also is two reaction tank series operations, and DAT holds continuous water inlet aeration, the IAT intermittent operation, and such dual system can be avoided the waterpower short circuit, and takes up an area of for a short time, and can carry out denitrogenation dephosphorizing.Sewage at first enters the IAT section again behind the preliminary biochemistry of DAT section, because continuous aeration played the waterpower proportionality action, improved the stability of whole technology, further removes organic pollutant in the sewage in the IAT section by the Degradation of microorganism then.The hydraulic detention time of reaction tank average discharge is 16.5h, and mud 44.3d in age can remove hardly degraded organic substance.
BAF is often used with the acidication process combination, wherein hydrolytic tank mostly is the modified version of up-flow anaerobic sludge blanket (UASB), the sludge blanket that in the pond, has certain altitude, collection biological degradation, physics sedimentation and biology are adsorbed as one, particle in the sewage and colloid pollution thing are trapped and adsorb, and obtain degraded under action of microorganisms such as acid formers.Hydrolytic tank has remarkable removal to intestinal bacteria and roundworm egg etc., and can improve the biodegradability of former water, helps follow-up aerobic treatment, has also reduced sludge yield simultaneously.And this mud through concentrate, water ratio is 75%～80% after the dewatering integrated device processes, can be used as fertilizer and use.Up-flow Biological Aerated Filter (UBAF), the filtering layer height is 3m, highly locates the aeration tube system is set at the 1m of filtering layer, makes filtering layer form oxygen-starved area and aerobic zone, and the part effluent recycling is carried out internal recycle to inhalant region, realizes denitrifying purpose in the oxygen-starved area.Adopt aluminium salt as dephosphorization agent, the calcium phosphate precipitation thing that reaction forms is removed by fabric filter.
Summary of the invention
The object of the present invention is to provide a kind of wastewater from hotel of energy-conservation odorless to handle and the reuse new technology, it is to adopt the little oxygen biological treatment-secondary of anoxic biological treatment-secondary aerobe processing-air supporting-filtration-UV sterilization and disinfection combination process to handle wastewater from hotel, make it reach reclaimed water matter standard.
Technical solution of the present invention is that wastewater from hotel enters after equilibrium that equalizing tank carries out water quality, the water yield regulates; enter the anoxic biological treatment tank by lift pump and carry out of short duration double oxygen biological hydrolysis, acidifying; waste water outflow enters the little oxygen biochemistry pool of secondary and carries out biochemical treatment; the water outlet gravity flow enters secondary aerobic biochemical pond and carries out the aerobic biochemical processing; carrying out coagulation air-float by dosing coagulant then handles; by carrying out reuse after quartz sand filtration and granulated active carbon cascade filtration and the UV virus killing, reuse water can reach the reclaimed water standard at last.
Method of the present invention and feature thereof are that it is formed by biochemical processing process and the optimum combination of materialization treatment process, and described biochemical processing process is by energy-conservation, the anoxic biological treatment of odorless, the little oxygen biological treatment of secondary and secondary the aerobic biological treatment process integrated integration apparatus of optimum combination successively; It is combination successively by as coagulation air-float and quartz sand filtration, gac filtration and the UV process for sterilizing of subsequent treatment process that described materialization is handled.
Described biological treatment tank is biological contact oxidation pond, biologic packing material all is installed in the pond, as combined stuffing, elastic solid filler, little oxygen biological tank and aerobic biological tank inner bottom part all are equipped with micro-pore aeration system, the DO in the little oxygen of secondary pond is controlled at 0.3～0.5mg/L respectively, 0.5～1.0mg/L, the DO in the secondary aerobic biochemical pond is controlled at 1.5～2.0mg/L, 2～4mg/L respectively.
In the described follow-up materialization treatment process, coagulating agent aluminium salt is as PAC, Al
2(SO
4)
3The partial reflux pressurized dissolved air flotation is adopted in air supporting; Filter and adopt quartz sand filtration, perhaps quartz sand filtration adds follow-up gac filtration; Sterilization and disinfection adopts UV254.
The invention has the beneficial effects as follows: (1) anoxic biological treatment residence time is short, can not produce stench, has eliminated the H that conventional anaerobic biological treatment occurs
2The S odor pollution; (2) little oxygen biological treatment can not produce odor pollution, has eliminated the stink of anaerobic treatment, compares with aerobic treatment, has reduced aeration rate, has reduced energy consumption; (3) anoxic, little oxygen and aerobic biological treatment process successively optimum combination form, treatment effect is good, organic matter removal efficient height, water outlet can reach national composite wastewater first discharge standard.Disinfect through follow-up air supporting, filtration and UV, quality of reused water standard and requirement are satisfied in water outlet, can be used as reclaimed water.
