Description
[technical field]
The utility model relates to the high concentrated organic wastewater processing technology field, specifically a kind of organic waste water anaerobic reaction device.
[background technology]
Along with the develop rapidly of production-scale continuous expansion and industrial technology, the source of pollution of high concentrated organic wastewater are increasing, brought serious water pollution problems.Seeing that the character of high concentrated organic wastewater is different with the source; And it administers comparatively difficulty; Adopt general method for treating wastewater to be difficult to satisfy the economy and the technical requirements of purifying treatment, therefore how administering high concentrated organic wastewater has effectively become the difficult problem that present stage international environmental protection technical field urgently waits solution.
High concentrated organic wastewater mainly has following characteristics:
The one, organic concentration is high.COD generally more than 2000mg/L, have in addition up to several ten thousand and even hundreds of thousands of mg/L, comparatively speaking, BOD is lower, the ratio of a lot of waste water BOD and COD is less than 0.3.
The 2nd, complicated component.It is in the majority with aromatics and heterogeneous ring compound to contain in the toxicant waste water organism, more than contain sulfide, nitride, heavy metal and toxic organic compound.
The 3rd, colourity is high, and peculiar smell is arranged.Some waste water gives out pungent stench, causes detrimentally affect to surrounding environment.
The 4th, have strong acid and strong base property.In the ultra-high concentration organic wastewater that industry produces, acid, bases are numerous, often have strong acid or strong basicity.
The harm one of high concentrated organic wastewater is aerobism harm: because biological degradation, high concentrated organic wastewater can make receiving water body anoxic base to anaerobism, and most aquatic organisms are with death, thereby the generation stench worsens water quality and environment.The 2nd, the sense organ contact scar: high concentrated organic wastewater not only makes water body lose use value, more has a strong impact near the people's of water body orthobiosis.The 3rd, intoxicating property harm: contain a large amount of toxic organic compounds in the ultra-high concentration organic wastewater, can in physical environments such as water body, soil, constantly accumulate, store, get into human body at last, be detrimental to health.
The treatment technology of high concentrated organic wastewater is divided into 3 types roughly: materialization treatment technology, chemical treatment skill and art biologic treating technique.Though utilize the removal efficient of physics and chemical process processing organic wastewater with difficult degradation thereby very high, processing cost is too high.Pretreated physical chemistry method is a lot of before the waste water, has that coagulation, neutralization, filtration, oil removal, gas are carried, little electrolysis, absorption, chemical oxidation and anaerobic acidification etc.The absorption preconditioning technique is widely used in clean water treatment already, also on engineering, use for lower concentration chemical industry Wastewater Pretreatment, but to high concentrated organic wastewater, processing cost is too high, influences it and on engineering, applies.UW is a kind of form of energy that is different from light and heat, utilizes the compression and the expansion of ripple, in water, forms small bubble; Solute and solution molecule form steam in bubble; In bubble, produce instantaneous high pressure and high temperature owing to the compression of ripple, making has the generation of OH radical in the steam, but the energy consumption of ultrasonic technique is bigger; Noise is serious, handles the whether economy further research of still needing of a large amount of waste water.Hydrolysis method is utilized part hardly degraded organic substance unsettled character under acidity or alkaline condition exactly; Through regulating the pH value of waste water; Thereby the method that hardly degraded organic substance is decomposed, but the deficiency of hydrolysis method is that the consumption of soda acid is big, has wasted big water gaging because of further diluting after the hydrolysis; Therefore the expense of unit water treatment is very high, is difficult to interior the popularization on a large scale.
