Description
Technical field
The utility model relates to a kind of biological effluent treatment system, belongs to the technical field of environment protection.
Background technology
Alcohol fuel has the features such as clean, renewable, the discharge of carbon monoxide and hydrocarbon polymer in vehicle exhaust can be reduced, it is the important component part of renewable energy source, at substitute energy, environmental protect, promote agriculture industrialization, realize the aspect such as growth of agricultural efficiency, increasing peasant income and there is vital role.At present, the strategic planning of national development alcohol fuel requires " do not strive grain with people, do not strive ground with grain ", and the non-grain alcohol fuel of positive scientific development, adheres to based on non-grain, encourages raw material diversification, becomes Fuel Ethanol development trend.Potato starch matter alcohol fuel mainly comprises the root such as cassava and Ipomoea batatas uncooked amylum raw material, because it has processing characteristics good, be applied to the desirable alternative materials of extensive fuel ethanol production, a large amount of acidic high-temperature high concentrated organic wastewater is produced in potato class non-grain starchiness fuel ethanol production process, often produce 1t alcohol fuel and can produce 11 ~ 15t processing wastewater, wastewater temperature is more than 60 DEG C, pH is 4 ~ 5, COD (chemical oxygen demand (COD)) is 40000 ~ 80000mg/L, viscosity is large, high and the not easily solid-liquid separation of suspension content, but also facing to great number of issues in the treating processes of the waste water produced in non-grain starchy material production alcohol fuel process at qualified discharge: as suspension content is high, intractability is large, processing cost is high, be difficult to be applied to extensive industrialized development etc.Anaerobic-aerobic combination process is the classical technique of fuel ethanol wastewater process.Traditional fuel ethanol wastewater is generally after solid-liquid separation, adopt " one-level anaerobism+aerobic " art breading, but there is pre-treatment costly in traditional technology, investment is large, unstable, thus follow-up anaerobic treatment is made troubles, easily system is impacted, suspended solids content in addition due to such waste water is higher, application high efficiency anaerobic reactor UASB, there is unfavorable factor in EGSB, and there is the residues such as cassava and enter the blockage problem that treatment system causes, large-scale complete mixed anaerobically fermenting not easily stirs, sludge loss problem (digested sludge not easily precipitates recovery) etc., one-level anaerobic effluent viscosity is large simultaneously, solid-liquor separation difficulty, full lees wastewater anaerobic operation volumetric loading is usually at 2.5KgCOD/m
3about d, affects fuel ethanol production and economic benefit, and traditional method is back to one-level high temperature anaerobic tank after thermophilic digestion liquid need being carried out mud separation, causes energy consumption and investment greatly to increase, is not suitable for larger processing system.Before entering secondary anaerobic, suspended substance can not effectively be removed simultaneously, and SS content is still up to 6000 ~ 12000mg/, and the continuous high-efficient having a strong impact on the anaerobic reactors such as follow-up UASB runs.Can not extract the energy (biogas) in waste water to greatest extent, can not effectively be removed by ammonia nitrogen, total nitrogen after traditional aerobic process process, the clearance of nitrogen phosphorus is difficult to reach stable effect simultaneously.Patent " potato class non-grain starchiness alcohol fuel grain liquid processing method " discloses a kind of method of fuel ethanol wastewater process, but secondary anaerobic reactor adopts UASB in the method, gas stirring intensity is more weak, ydrodynamics is poor, add water quality viscosity large, cause mass transfer effect not good, COD clearance is only about 50%.Follow-up aerobic biochemical technique, owing to lacking high-quality carbon source, causes nitric efficiency to decline.
Disclose a kind of fuel ethanol wastewater treatment unit for a kind of high efficiency anaerobic reactor for the process of fuel ethanol wastewater secondary anaerobic of above-mentioned defect patent, to promote anaerobic treatment efficiency, take into account and promote follow-up denitrification effect.But there is the gathering of biofilm carrier in this fuel ethanol wastewater treatment unit in use easy top at reactor, and adopt the zone design that multistage is separated, be unfavorable for the circulation of biofilm carrier, cause the microorganism in fluidized-bed can not realize many generation circulations to select, be unfavorable for that in microbial film, microorganism carries out Genetic evolution towards the direction more adapting to treating material.And often can with the biofilm carrier of anaerobe film in the material exported in this reactor, the membrane bioreactor of contaminate subsequent.
