Abstract

A process for treating the life and industrial sewage includes such steps as pre-treating, and flowing in an internally circulating biologic fluidized-bed reactor, where the biochemical reaction, oxidizing reaction, and separation take place.

Description

Small town living, industrial sewage process method
Technical field
The present invention relates to live, the treatment process of industrial sewage, belong to environmental technology field.
Background technology
Development along with Chinese Urbanization; the quantity of samll cities and towns is increasing; the development of samll cities and towns is important channels of Chinese Urbanization; but the development of samll cities and towns has also brought the water environment pollution that has a large capacity and a wide range always according to Environment Protect in China long-range objectives outline, and China will reach in the time in 10 years that the city domestic sewage processing rate is not less than 60%, the trade effluent level of qualified discharge basically.Realizing this goal not only needs to build large quantities of sewage works, and presses for the treatment technology of high-efficiency low energy consumption.The environmental protection problem that solves in the One's name is legion Development of Small Cities and Towns will be significant to the strategy of sustainable development that China implements.
It is core that samll cities and towns' biological fluidized bed combined-type sewage is handled with unitary efficient low-consume sewage biochemical processing process.Reaction principle is based on the philosophy and technique of organism fluidization reactor.Aerobic biological fluid-bed technology in the wastewater treatment is to grow up at the seventies initial stage, it is based on biomembrance process, having drawn the fluidization technology in the chemical industry operation, formed a kind of high-efficiency wastewater treatment, is the important breakthrough that biomembrance process is handled waste water technology.
Since the eighties, many investigators begin the three-phase biologic fluidized-bed broad research of having carried out has been obtained certain achievement.The processing that people such as PAUL HUPPER utilize the three-phase biologic fluidized-bed focusing olein of outer circulation type to heat up in a steamer waste water is carried out in research.For prevent that undesirable microorganism from growing, and adopted level two on carrier.Its technical process is: waste water is handled through first step aerobe earlier, and its device is an improved active sludge inner circulation reactor, gets rid of to enter the three-phase biologic fluidized-bed secondary aerobe that carries out of outer circulation again behind the easy matrix degradation behind sedimentation and filtration and handle.
Summary of the invention
The object of the invention is to samll cities and towns provide that a kind of input cost is low, the life of easy handling, industrial sewage process method.
The present invention carries out pre-treatment earlier with sanitary sewage, enters the three-phase inner loop fluidized bed reactor reactor with biochemical reaction, demoulding and isolation integral again, allows sewage stay for some time in reactor and carries out oxidizing reaction, obtains meeting the clear water of emission request; Described three-phase inner loop fluidized bed reactor reactor is provided with labyrinth type bio-carrier separator, dissolved air flotation device, fluidized reaction zone, the labyrinth type bio-carrier separator is positioned at three-phase inner loop fluidized bed reactor reactor middle part, air supporting and organism fluidization reactor are coupled, around the dissolved air flotation device is the high efficiency separation district, the both sides up and down of labyrinth type carrier separator are the reactor buffer zone, are fluidized reaction zone below it.
Because the high-efficient characteristic of biological fluidized-bed reactor makes the unit reactor volume have sewage treatment capacity far above other bio-reactor, thoroughly change high-efficiency aerobic technology be provided with the maximization of organism fluidization reactor in solid-liquid separation time of existence greater than the problem in reaction times.The labyrinth type bio-carrier separator solves the separation problem of bio-carrier under the fluidized state, reduces the loss of bio-carrier, prolongs carrier life, can further reduce moving row cost.Air flotation technology is a kind of solid-liquid separation technique efficiently, air supporting and organism fluidization reactor are coupled, form the NEW TYPE OF COMPOSITE reactor, not only improved the efficient of solid-liquid separation, and can save the processing unit that the space is used for reactor, improved the wastewater treatment ability of unit volume reactor greatly.Therefore the present invention can make the volume of reactor of employing little, production cost is low, and technology is simple, handled easily, working cost is low, can be applicable to small town sewage processing and chemical industry, pharmacy, prints and dyes, brewages, the processing of trade effluent such as grease processing, sugaring.
Fluidized reaction zone comprises aerobic zone and oxygen-starved area.Under the ciculation fluidized state of high speed, in reaction zone, form the stable rational structure of reactor of oxygen-starved area needs, suitable fluidised form condition and corresponding oxygenation intensity, the formation of oxygen-starved area is the removal of organic pollutant and nutritive element (N), and obtains the gordian technique of high-level efficiency and less energy-consumption.
The bio-carrier of three-phase inner loop fluidized bed reactor reactor is the light-high-strength biologic packing material.Not only can reduce the fluidizing power consumption, and be easy to adhering to of microorganism, help improving the biomass in the reactor.
Above-mentioned light-high-strength biologic packing material can be haydite.Can further improve separation efficiency.
Be provided with the honeycomb section in the three-phase inner loop fluidized bed reactor reactor, send out the structural strength of reactor with reinforcement, and make fluidisation more even.
Specific embodiment
Sanitary sewage is carried out pre-treatment earlier, remove the large-sized solid foreign material, enter three-phase inner loop fluidized bed reactor reactor again, allow sewage in reactor, stay for some time and carry out oxidizing reaction, obtain meeting the clear water of emission request biochemical reaction, demoulding and isolation integral.
Above-mentioned three-phase inner loop fluidized bed reactor reactor is provided with labyrinth type bio-carrier separator, dissolved air flotation device, fluidized reaction zone, the labyrinth type bio-carrier separator is positioned at three-phase inner loop fluidized bed reactor reactor middle part, air supporting and organism fluidization reactor are coupled, around the dissolved air flotation device is the high efficiency separation district, the both sides up and down of labyrinth type carrier separator are the reactor buffer zone, be fluidized reaction zone below it, fluidized reaction zone comprises aerobic zone and oxygen-starved area.
The bio-carrier of three-phase inner loop fluidized bed reactor reactor is a haydite, or other light-high-strength biologic packing material.
Be provided with the honeycomb section in the three-phase inner loop fluidized bed reactor reactor.
