What is industrial wastewater treatment?
什麼是工業廢水處理？
The wastewater produced in certain industries can contain a number of by-products that should not enter the natural water supply. As a result, many of these industries have their own inhouse wastewater treatment plant so that the treatment can be specifically tailored to the contaminants that their process produces. This allows them to comply with any industry-specific regulations. These treatments may include removal of toxic materials, acids and alkalis, treating brine, and removal of various solids. In some facilities, the wastewater may undergo the complete treatment process and be released back into the environment. In others, it may be partially treated, then sent to the municipal wastewater treatment plant. Although the industry and the products to be removed vary and additional steps may be necessary, the general process remains largely the same: filtration followed by aeration. Just as in a municipal wastewater treatment plant, blowers or compressors are used to provide airflow to the aeration tank. However, as the wastewater can contain different and potentially harmful chemicals, there may be different requirements for the blower or compressor, such as corrosion resistance.
某些行業產生的廢水可能含有大量不得排入自然水源的副產物。因此，此類行業多數擁有專門的內部廢水處理廠，可根據製程所產生的污染物針對性打造廢水處理。這樣才能遵守相應行業特定的法規。處理可包括去除有毒物質、酸鹼、處理鹽水以及各種固體。 在部分設施裡，廢水可能經過完整的處理製程，再回歸大自然。在其他情況下，廢水可能僅經過部分處理，然後送往市政廢水處理廠。 儘管行業和需要去除的物質各不相同，還可能需要額外步驟，但整體製程大致相同：過濾後進行曝氣。與市政廢水處理廠類似，使用鼓風機或壓縮機為曝氣池提供氣流。不過，由於廢水可能含有不同的潛在有害化學物質，因此對鼓風機或壓縮機的要求也各不相同，例如防腐蝕性。
