Description
(1) technical field
A kind of reactor in the utility model based environment engineering, environmental chemistry, Environmental Biotechnology and the water-treatment technology field particularly relates to a kind of employing photochemical catalytic oxidation and the incorporate water processing reactor of biological degradation.
(2) background technology
Present technique belongs to a kind of device of environmental engineering, biochemical reaction engineering, Environmental Biotechnology and water technology.Along with the continuous development of industrial and agricultural production and improving constantly of people's living standard, a large amount of dischargings of various industrial and agricultural wastewaters and sanitary sewage cause the water body in many natural rivers, lake, view waters even drinking water source all to be subjected to pollution.Its major cause is nitrogen and phosphorus content severe overweight.In some surface water even also contain the poisonous and hazardous organic pollutant of a large amount of difficult degradations, show as the feature of combined pollution.These pollutents cause natural water bodies such as river, lake and view waters all multi-functionally has been subjected to the pollution that destruction, especially drinking water resource be subjected to people's ordinary production and life has all been caused great harm.Therefore adopt a kind of good technological method or develop once the advanced water treatment device of cover and the trade effluent that contains Persistent organic pollutants is effectively handled and administered or repair extremely urgent natural water body.
When containing organic wastewater with difficult degradation thereby and carry out a biological disposal upon, sometimes because some organism to the restraining effect of microorganism, causes treatment effect not good.For this reason, generally adopting high-level oxidation technology that this class waste water is handled is a kind of efficient ways, after for example adopting photochemical catalytic oxidation that this class water is handled, can destroy organic molecular structure, utilize biological method to carry out subsequent disposal again, can make these organic compound obtain mineralising, change nontoxic material into.This is because some organic compound through after the photocatalytic oxidation degradation, changes into easily by biodegradable product.But, normally two technology are carried out series combination both at home and abroad at present, promptly in a technology, photochemical catalytic oxidation and biological degradation are located at two reaction members respectively and carry out, obtained certain effect.
But the problem here is that organic wastewater with difficult degradation thereby arrives what degree biodegrade again by photocatalytic oxidation degradation, just can improve the efficient of wastewater treatment, is still the problem that needs solution.If earlier by photochemical catalytic oxidation long time treatment, then decrease in efficiency.Otherwise if the photochemical catalytic oxidation time is not enough, then microbiological deterioration can not effectively be carried out.
Therefore, photochemical catalytic oxidation and biological degradation being combined into one, is the effective ways that address this problem.This is because hardly degraded organic substance be in case after being turned to biodegradable material by photocatalytic-oxidation, then can be degraded by microorganisms immediately, and when not being oxidized to a certain degree, then can continue by photochemical catalytic oxidation.For this reason, the utility model patented technology then is a kind of incorporate reactor of developing at this content.
(3) utility model content
The purpose of this utility model is to overcome prior art and utilizes photochemical catalytic oxidation and biodegradation technique above shortcomings, and the reactor that provides a kind of novel photochemical catalytic oxidation and biological degradation to be closely as one improves the efficient of water treatment.
The purpose of this utility model is realized by following structure.
The incorporate air lift type inner circulation reactor of a kind of photochemical catalytic oxidation and biological degradation, it is characterized in that: the vertical reactor top that is tubular is provided with water outlet, vertical two workspace about reactor axially is provided with a photochemical catalysis plate reactor is divided into, promptly half is a bio-reaction zone for photochemical catalytic oxidation district and half;
In the photochemical catalytic oxidation district, ultraviolet source is set;
In bio-reaction zone, place biofilm carrier, offer water-in in the bottom of bio-reaction zone;
At reactor lower part aerator is set;
Offer the excess sludge discharge mouth in the bottom of reactor.
In described photochemical catalytic oxidation district, repeat to be provided with photochemical catalysis plate and ultraviolet source at interval successively in the ultraviolet source outside, outermost, promptly not limitting near reactor wall is photochemical catalysis plate or ultraviolet source.
In the upper end of described photochemical catalysis plate, bio-reaction zone one bogie side frame is established grid, prevents that microbial film is pulled away in the aeration uphill process.
Described biofilm carrier is a proportion less than 1 light porous material.
Described aerator is arranged on the bottom in photochemical catalytic oxidation district.
Described aerator is arranged on the bottom of bio-reaction zone.
The described cross section that is the vertical reactor of tubular is circle.
The described cross section that is the vertical reactor of tubular is square.
The technical program has designed a kind of photochemical catalytic oxidation and the incorporate reactor of biological degradation.Adopting wherein, a photochemical catalysis plate is divided into reactor photochemical catalytic oxidation district and bio-reaction zone between two parties.Because the effect of this division board can make the interior microorganism of bio-reaction zone avoid uv irradiating and keep biological activity.The aeration of bottom aerator can make water form internal recycle in reactor, and pending water is constantly by bio-reaction zone and photochemical catalytic oxidation district, thus the efficient of raising water treatment.Look the size in photochemical catalytic oxidation district, can repeat to be provided with again some photochemical catalysis plates and ultraviolet source at interval successively in the ultraviolet source outside as required, outermost, promptly not limitting near reactor wall is photochemical catalysis plate or ultraviolet source.
Advantage of the present utility model and beneficial effect:
The utility model provides a kind of photochemical catalytic oxidation and the incorporate reactor of biological degradation, in this reactor organic wastewater with difficult degradation thereby by behind the photocatalytic oxidation degradation in inner natural circulation biodegrade again, can improve the efficient of wastewater treatment.
This reactor assembly compact construction has changed the structure of pre-existing reactors fully, and a kind of water technology of efficient fast energy-saving is provided, and to the protection environment, " energy-saving and emission-reduction " all have crucial meaning.
