Technical field
The utility model relates to the treatment unit of coal chemical industry enterprises gas washing wastewater, refers to that particularly a kind of coal chemical industrial waste water is processed into covering device.
Background technology
China is since carrying out coal chemical industrial waste water processing engineering last century, generally that employing anaerobism, aerobe method processing are also A/O technique, but due to many rings and the heterocyclic compound in coal chemical industrial waste water, the COD index after aerobe method is processed in water outlet is difficult to stably reaching standard.And along with country to the raising of sewage drainage standard and the demand of low operating cost and environmental type recycling economy, the Coal Chemical Industry industry will be faced with wastewater processing technology and be badly in need of the improved predicament of upgrading with device.The coal chemical industry enterprises waste discharge contains the poisonous and harmful substances such as a large amount of phenol, cyanogen, oil, ammonia nitrogen take the high density gas washing wastewater as main.In comprehensive wastewater CODcr generally at 5000 about mg/L, ammonia nitrogen at 200～500 mg/L, the contained organic pollutants of waste water comprises heterogeneous ring compound of phenols, polycyclc aromatic compound and nitrogenous, oxygen, sulphur etc., these organic pollutants very major part belong to carbon source inferior, being difficult to be utilized by biochemistry, is a kind of trade effluent that typically contains the organic compound of difficult degradation.
Summary of the invention
The purpose of this utility model to provide exactly a kind of reaction start fast, processing efficiency is high, stable operation, product sludge quantity are few, the simple coal chemical industrial waste water of solid-liquid separation is processed into covering device, by process targetedly the waste water that contains the difficult degradation organic poison with immobilized biotechnology.
for achieving the above object, the designed coal chemical industrial waste water of the utility model is processed into covering device, comprise extraction tower, the extraction tower outlet is connected with the ammonia still import, the ammonia still outlet is connected with oil trap, oil trap is connected with air flotation pool, air flotation pool is connected with upflow anaerobic sludge blanket process, upflow anaerobic sludge blanket process and immobilized microorganism enhancement type anaerobism, the aerobic reactor aerobic section connects, immobilized microorganism enhancement type anaerobism, aerobic reactor aerobic section and immobilized microorganism enhancement type anaerobism, aerobic reactor anaerobism section connects, immobilized microorganism enhancement type anaerobism, aerobic reactor anaerobism section is connected with flocculation sedimentation tank, flocculation sedimentation tank is connected with the ozone high grade oxidation fixed bed, the ozone high grade oxidation fixed bed is connected with shallow media filter.
As preferred version, described air flotation pool is supporting air dissolved pump, dissolving and air compressor machine.
The utility model has the advantage of: it is also that anaerobism, aerobic process are transformed into immobilized microorganism enhancement type anaerobism, aerobic reactor that the utility model is processed anoxic, aerobe method, biochemical technology by improvement, take biochemical treatment as main processing unit, reduced cost, the strain degradation ability strengthens at double, produce water water quality good, this system is to COD, NH
3-N clearance can reach more than 97%, COD, NH
3-N etc. can satisfy up-to-date emission standard; The biochemical treatment unit use through optionally and the fixedly dominant bacteria of having tamed to the contaminant degradation in waste water can the high 2-5 of force rate common sludge doubly, and degradation efficiency is also higher.Compare with traditional wastewater processing technology, it has reaction and starts fast, the advantages such as processing efficiency is high, stable operation, the product sludge quantity is few, solid-liquid separation is simple.
