Description
Technical field
The present invention relates to waste-water separator, especially relate to the separator that is used for isolating the waste water ammonia nitrogen.
Background technology
Industries such as chemical industry, chemical fertilizer, petrochemical industry and coking are the industrial large users of discharging high-concentration ammonia nitrogenous wastewater, and the separation of waste water middle and high concentration ammonia nitrogen is the most unmanageable operation of above-mentioned trade effluent.At present, the method of ammonia nitrogen separating treatment mainly contains following several in the waste water: a kind of is physico-chemical process, it comprises blow-off method, ion exchange method, break oxidation style, wet oxidation process, chemical precipitation method, membrane filter method and high temperature evaporation method, the problem that this method mainly exists is that processing efficiency is low, processing cost is high, and the practical application promotional value is not high; Two kinds is the A/O method, and it comprises A/O, A
2/ O and A
2/ O
2Method, this method is that the process by nitration denitrification makes ammonia nitrogen degradation in the waste water, but the problem that this method mainly exists is that the aeration tank initial cost is big, running cost is high, operation condition harshness, (ammonia-nitrogen content should be less than 300mg/L for influent quality Gao Qiugao, the COD index is less than 1000mg/L), the operation process range is narrow; The third is the method that domestic and foreign current is handled high-concentration ammonia nitrogenous wastewater, it is earlier high-concentration waste water to be dropped to ammonia nitrogen in the waste water below the 300mg/L by stripping or stripping, handle with the A/O method, and then handle with decoloring method, the ammonia nitrogen separation reaches emission standard in the high-concentration waste water though this method can be used, but this method treatment process is long, and processing efficiency is low, the processing cost height.
Summary of the invention
Problem at ammonia nitrogen separating treatment existence in the waste water in the above-mentioned prior art, the invention provides a kind of characteristic of utilizing ammonium salt and free ammonia ratio in the waste water to change with the variation of waste water pH value, adopt the mechanical separation ammonia nitrogen in waste water, and treatment effect is good, the apparatus for separating ammonia nitrogen in waste water that processing efficiency is high.
The technical scheme that the technical problem to be solved in the present invention is taked is: apparatus for separating ammonia nitrogen in waste water is connected in parallel in the denitrification tank, described apparatus for separating ammonia nitrogen in waste water comprises housing, rotating shaft, separating bucket, liquid distributing board, gas distribution grid, described case top is provided with gas outlet tube and liquid inlet tube, be provided with gas inlet tube in the housing side, be provided with liquid outlet tube at housing bottom, be provided with rotating shaft at the housing center, be set with one deck liquid distributing board at least at the housing inner chamber, be set with the separating bucket of band sorting hole in the rotating shaft below every layer of liquid distributing board, on the housing inner chamber at separating bucket middle part, be set with gas distribution grid, gas distribution grid is provided with ventilating pit, described separating bucket is taper shape or helically coiled, be provided with liquid flow hole in the middle of liquid distributing board, the liquid flow hole diameter is less than the big opening diameter in separating bucket upper end.
The characteristic that the ratio that the present invention utilizes ammonium salt and free ammonia in the waste water changes with the variation of waste water pH value, by regulating the rotating shaft rotating speed, after making waste water pass through the separating bucket of high speed rotating, sorting hole from separating bucket disperses to eject the formation fine liquid particles, water droplet fully contacts with the pressurized gas that sprays from ventilating pit and atomizes, with the ammonium salt in the waste water with free ammonia is separated and discharge with pressurized gas, thereby reach the ammonia nitrogen effect that separates in the waste water.Because waste water repeatedly fully contacts under high speed rotating with pressurized gas and produces atomizing, thereby ammonia nitrogen good separating effect in the waste water, the separation efficiency height, compact construction of the present invention, fitting operation is convenient, reliable safety.
