气体排放:(1)焙烧炉的废气,由各自高压静电除尘收尘净化后,分两座75m的烟囱排入大气,并达到《工业炉窑大气污染物排放标准》二级标准要求。(2)熟料烧成回转窑窑尾废气,由各自旋风+板卧式电除尘器收尘净化后,由3座100m的烟囱排放入大气,并达到《工业炉窑大气污染物排放标准》二级标准要求。(3)锅炉烟气采用炉内石灰石脱硫+袋式除尘技术处理,处理后由120m的烟囱排空,排放烟气中烟尘及二氧化硫浓度均代于《火电厂大气污染物排放标准》(GB13223-2003)Ⅲ时段的标准值。(4)石灰炉产生的废气经喷淋塔和湿式电除尘器二级净化后排放。(5)氧化铝生产系统在生产中均会产生一些无组织的散发性粉尘,由设计中各个散尘点设置集尘罩并辅以机械抽风,同时设置高效布袋除尘器,排放含尘浓度低于《大气污染物综合排放标准》中的二级标准值。

Gas emissions: (1) calciner waste gas, receives the dust purification after respective high-pressured static electricity dust removal, the weight place 75m chimney disperses into the atmosphere, and achieves "Industry Dry kiln Air pollutant Emissions Standard" two level of standard requests.(2) chamotte fires the rotary kiln kiln tail waste gas, receives the dust purification after respective tornado + board horizontal type electric precipitator, discharges into the atmosphere by 3 100m chimneys, and achieves "Industry Dry kiln Air pollutant Emissions Standard" two level of standard requests.(3) boiler haze uses in the stove limestone desulphurization + bag type dust removal technology processing, after processing by the 120m chimney evacuation, in the emissions haze the mist and dust and the sulphur dioxide density generation in "Thermoelectric power station Air pollutant Emissions Standard" (GB13223-2003)ⅢTime interval normal value.(4) limestone kiln produces the waste gas purifies after the spray tower and the wet electric precipitator two levels discharges.(5) aluminum oxide production system can produce some non-organization's sending out dust in the production, disperses the dust establishment dust cage one by one by the design in and auxiliary by the mechanical convulsion, simultaneously establishes the highly effective cloth sack dust remover, discharges is lower than "Air pollutant Synthesis Emissions Standard" including the dust density the two levels of normal values.
Solid emissions: Red putty leaves which by each section of settling out back row, after passes through washes many times enters the red putty dump site by the high-pressured mutual lack of understanding pump house pump over.
