Background technology:
Compare with town domestic sewage, though the high-concentration industrial-water water yield is few, Organic pollutants are serious, pollute the total amount height.The pharmacy waste water of producing the erythromycin of 800t with year is an example, its day, the sewage effluent amount was 2000t, COD in the sewage (chemical oxygen demand (COD)) concentration is 30000mg/L, the COD total amount that its produces every day is 60t, is equivalent to the organic pollutant total amount (the sewage discharge total amount of organic that was equivalent to for 1,000,000 population every days approximately) of the town sewage plant of 150,000 a tons/d.The industry that high-concentration industrial-water relates to is more, as pharmacy, Coal Chemical Industry, fine chemistry industry, APMP papermaking and black liquor, petrochemical industry or the like, the major fields that are related to national economy mostly, principal pollutant that relate to such as phenyl ring class, phenols, nitrile, ketone, amides, alkanes, polymer class, prussiate etc. are difficult degradation, high microorganism inhibitory substance.
A series of water pollutions, the deterioration of the ecological environment, the threat HUMAN HEALTH that causes by this class high-concentration industrial-water, hinder problem such as related industries development, more and more be subjected to the extensive concern of various circles of society and environmental administration of governments at all levels.Because economy and the technical requirements of adopting conventional biology or physico-chemical purification method to be difficult to or to satisfy purifying treatment make the purifying treatment of this class high-concentration industrial-water become a difficult problem that needs to be resolved hurrily in the present stage home and abroad environment resist technology field.
Current, high density, indegradable industrial effluent lack processing mode efficient, economical rationality, lack stable, reliable pre-treatment or advanced treatment means.Many effects limit such as generally pre-treatment of Cai Yonging and advanced treatment process are main high-level oxidation technology by film processing, activated carbon adsorption, Fenton reagent mainly, and working cost is high, cost of investment is huge, stabilization of equipment performance and specific aim are not strong its widespread use in high density, used water difficult to degradate treatment process.Emerging evaporation technique (such as the LZD[Liquid Zero Discharge of GE Berz] technology) on high density, indegradable industrial effluent, also obtained certain application, its cost with high investment (ten thousand yuan of ton water investment 5-10), the burning problem of dope, the branch problem of volatile pollutent, working cost high (100～200 yuan/t water) will limit its widespread use in the trade effluent field.
For improving the treatment effect of high density, indegradable industrial effluent,, feasible, economic, solution is efficiently proposed for trade effluent mechanism provides brand-new waste water solution.
Summary of the invention
For solving problems such as the biochemical efficiency that exists in present high density, the used water difficult to degradate treating processes is low, biological process is suppressed, the object of the present invention is to provide a kind of device for catalyzing and oxidating ozone that strengthens wastewater biodegradability, use this device can reach following purpose: (1) improves the contact efficiency of ozone and pollutent, reduces the consumption concentration of ozone; (2) biodegradability of raising waste water, under identical ozone concn situation, the biodegradability of waste water further promotes; (3) catalyst themselves has oxidisability, and produced simultaneously lower valency oxide compound is again the catalyzer of ozone oxidation process; (4) remove most colourities in the waste water.
Goal of the invention of the present invention is achieved by the following technical solution.
A kind of device for catalyzing and oxidating ozone efficiently, comprise coagulative precipitation tank, the ozone reaction tower, ozonizer, pump and valve, coagulative precipitation tank coagulation section is divided into three lattice, the pH regulator agent is housed respectively, catalyzer and flocculation agent, coagulative precipitation tank connects the ozone reaction tower, waste water enters the ozone reaction tower through post precipitation in coagulative precipitation tank, be provided with interlayer and aerating apparatus in the ozone reaction tower, aerating apparatus links to each other with the ozonizer that produces aeration, ozone is through the abundant contact reacts of hard-degraded substance in aerating apparatus and the waste water, utilize ozone molecule under the effect that catalyzer exists, the hydroxyl radical free radical survival life-span has been improved hundreds of times, thereby has improved the utilising efficiency of ozone, and this moment, wastewater biodegradability was greatly strengthened, can enter follow-up biochemical system, carry out advanced treatment.
Catalyzer needs to work under certain pH condition, can bring into play its oxidation capacity.The pH regulator agent can be sodium hydroxide, calcium hydroxide, yellow soda ash or the like, and it is 10～11 that the pH value is regulated in the pH regulator agent.Catalyzer is 1～5h in the total residence time of coagulative precipitation tank, is preferably 2～3h.The concentration that adds of catalyzer is 1～10mg/L, is preferably 4-6mg/L.
Ozonation aerated head and support need be selected the infrastructure device of titanium alloy, thereby guarantee corrosion-resistant, ozone transfer efficiency.Ozonation aerated concentration is general suitable with removal COD amount.Containing in the described ozone reaction tower increases the ceramic-like of contact efficiency filler.
Use the treating processes of apparatus of the present invention that wastewater treatment water quality is not had rigid requirement, relatively the waste water of Shi Heing is the low waste water of biodegradability, and the various water yields and water quality waste water can both effectively move.
Apparatus of the present invention adopt basic catalyst to produce nano level nascent state catalyzer in coagulation-settlement process, the waste water that contains catalyzer enters fully reaction in the ozone contact tower, utilize catalyzer to have the survival life-span of improving hydroxyl radical free radical, thereby effectively reduce quinoline, furans, prussiate, phenol in the waste water, improve the biodegradability of waste water.Apparatus of the present invention do not relate to biochemical treatment, and the treatment process that adopts physics, chemical process to combine is handled but handle the suitable biochemical system of back water outlet.
