The invention provides an urban surface runoff filtration system. The system comprises: a deposition chamber used for removing large-granule pollutants in surface runoff through deposition; a filtration chamber used for removing small-granule pollutants in the surface runoff through filtering adsorption of the surface runoff; and a water drainage chamber used for draining the filtered surface runoff through a water drainage pipe. The filtration system is applied in land space-limited urban roads and parking lots in a buried form, can efficiently remove pollutant granules in the surface runoff without influencing the surface functions, allows the removal rate of the pollutant granules to reach above 90%, and reduces the influences of the urban road and parking lot surface runoff pollution on the quality of receiving water.

The invention relates to the field of vanadium liquid purification, in particular to a method for removing silicon and phosphorus from a blank roasting-ammonia leaching vanadium extracting solution.

The present invention provides a column treating method by use of a distillation column and so on, which method enables to effectively remove solid impurities such as precipitates and polymers contained or produced in a treating fluid, and to thereby stably operate the column treatment. Solid impurities in a treating fluid can be removed by carrying out: step (a) of drawing out the treating fluid from a drawing out outlet (16) at the column bottom of the treatment column (10) outside the treatment column (10), step (b) of removing solid impurities from the treating fluid, drawn out in step (a), by a strainer (40), and step (c) of returning the treating fluid, from which the solid impurities are removed in step (b), to a returning inlet (18) of the treatment column, with advancing physical and/or chemical treatment of the treating fluid in the treatment column (10).

The invention discloses a method and a device for synchronously and efficiently removing nitrogen and phosphorus from low C/N domestic sewage by using an internal carbon source through a single-stage sequencing batch reactor, and belongs to the field of domestic sewage treatment. After domestic sewage enters the integrated short-cut nitrification endogenous short-cut denitrification phosphorus removal coupled anaerobic ammonia oxidation SBR reactor, an organic carbon source in the domestic sewage is converted into an internal carbon source in bacteria in a front anaerobic section, and the phosphorus release process is also completed; in the low-oxygen aeration stage, the phosphorus-accumulating bacteria absorb a part of phosphate in the sewage, and the ammonia-oxidizing bacteria oxidize ammonia nitrogen in a part of raw water into nitrite; and finally, in the anoxic section, part of nitrite and part of residual ammonia nitrogen generated in the aerobic section are converted into nitrogen by anaerobic ammonia oxidizing bacteria, the generated nitrate nitrogen is reduced into nitrite by denitrifying phosphorus-accumulating bacteria and denitrifying glycogen-accumulating bacteria, and the denitrifying phosphorus-accumulating bacteria further absorb phosphate. According to the method, the carbon source in the raw water is fully utilized to realize synchronous nitrogen and phosphorus removal of the low C/N domestic sewage, the ineffective loss of the carbon source is reduced, the energy consumption is reduced, and the sludge yield is relatively low.
