Abstract
The present invention discloses a kind of integrated photocatalytic waste water treating membrane apparatus. The apparatus is developed on the basis of available photocatalytic TiO2 apparatus and has increased ultrasonic catalytic probe to combine the cavitation of ultrasonic wave with photocatalysis to decompose various hard-to-decompose organic matters in waste water. The apparatus also includes membrane separator to separate treated water from TiO2 catalyst and membrane bioreactor for the standard reaching exhaust. The present invention has the advantages of continuous light-ultrasonic wave-biological treatment of organic matters in water in greatly raised degrading efficiency and lowered treating cost.
Description
Technical field
The present invention relates to a kind of waste disposal plant, a kind of TiO of utilization more specifically says so
2The device that photocatalytic oxidation is disposed of sewage.
Background technology
Delivered about TiO from Carey in 1976
2Since polychlorobiphenyl in the photocatalytic oxidation treating water (PCB) the dechlorination detoxification achievement, the research report that relevant photocatalytic oxidation is used aspect water pollution control is a lot, but it is less relatively to relate to the report of photoreactor application.
Traditional multiphase photocatalysis reactor is a kind of intermittent type cylinder shape photoreactor, and structure is very simple, operates also easily, and its outside is a columned Glass Containers, and upside has thief hatch, and gas distributor is arranged at the bottom.In the quartzy cold-trap of the double-deck U type of container central authorities, logical water of condensation keeps temperature of reaction system constant as the ultraviolet lamp vertical hanging of light source.This reactor is used for the active of evaluate catalysts or carry out the research of contaminant degradation rule by many investigators.This technology has formed product at present, and the dynamo-electric factory of the Nanjing Xu Jiang of Hispanic application optical physics company limited and China etc. is all making production, but does not have the ability of actual treatment sewage.
Simultaneously, organic efficient is not very high in the single light-catalyzed reaction degradation of sewage, and is not satisfactory for some difficult organic degradation effects that decompose yet.In addition, for the waste disposal plant of operate continuously, the separation of catalyzer does not solve well with recycling yet.Existing catalyst separating method separation efficiency is low, and the loss of catalyzer is more serious.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of high efficiency ultrasonic wave, integrated light catalytic waste water processing device by membrane method.
The present invention is at existing TiO
2Increase ultrasonic wave catalysis probe on the basis of photocatalysis apparatus, utilize hyperacoustic cavitation effect, and in conjunction with all kinds of difficult organism that decompose in the photocatalysis Decomposition sewage; The present invention also comprises a membrane separation unit, with water and the TiO after handling
2Catalyst separating; For making the sewage qualified discharge, the present invention also comprises a membrane bioreactor.
Advantage of the present invention is to realize the organism of light-sound-biological process in disposing of sewage continuously first, compares with single method, has improved degradation efficiency widely, has reduced processing cost.And can satisfy the processing needs of different components sewage according to the practical situation sequence of modules of rationally arranging work, degradation effect is better than other traditional method.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further specify the present invention below in conjunction with accompanying drawing and by specific embodiment.
As shown in Figure 1, pending sewage tentatively filters by mesh screen 1, removes impurity, stores in surge tank 2, enters ultraviolet/ultrasonic synergistic catalyticreactor 4 under the effect of pump 3.This reactor comprises ultraviolet lamp tube 5 and ultrasonic generator 6, also has TiO in the reactor
2Catalyzer.Sewage is through UV-irradiation and TiO
2Catalyzed oxidation, organic pollutant are broken down into nontoxic inorganic substance, and the mineral ion of part different valence state is also oxidized; For hard-degraded substance, start ultrasonic generator 6, realize acousto-optic concerted catalysis degradation process.After having decomposed, under the effect of pump 8, filter through ceramic microfiltration membrane 7, liquid is drawn out of, and catalyzer is trapped within the reactor, realizes the catalyzer repeated use.Liquid after the filtration is pumped in the membrane bioreactor 9, and the bacterium in active sludge engulfs down, and inorganics is engulfed, directly can discharge after filtering by ceramic microfiltration membrane 10 again, active sludge and bacterium are trapped, and recycling realizes complete and the successive sewage treatment process.
Through experimental results show that, for dyeing waste water, when realizing COD＜60mg/L through behind ultraviolet/ultrasonic synergistic film-catalyticreactor, colourity (extension rate)＜30, suspended substance (SS)＜50, pH=6-9 reaches or is better than national textile dyeing and finishing industrial water pollution thing emission standard GB4287-92 or integrated wastewater discharge standard GB 8978-1996 town B-grade sewage treatment plant first discharge standard.Through COD＜20mg/L behind the membrane bioreactor, colourity (extension rate)＜5, suspended substance (SS)＜10, pH=6-9, whole structure are better than existing Sewage treatment systems.
