| 一、表面处理废水 First, surface treatment wastewater 1.磨光、抛光废水 Polished and polished waste water 在对零件进行磨光与抛光过程中，由于磨料及抛光剂等存在，废水中主要污染物为COD、BOD、SS。 In the process of grinding and polishing the parts, the main pollutants in wastewater are COD, BOD and SS due to the presence of abrasive and polish. 一般可参考以下处理工艺流程进行处理：废水→调节池→混凝反应池→沉淀池→水解酸化池→好氧池→二沉池→过滤→排放 Generally refer to the following processing technological process for processing: waste water to adjust the pool, the coagulation reaction tank to tank, the hydrolysis acidification pool - aerobic pool - the second pond - filter - emissions 2.除油脱脂废水 Oil degreasing waste water 常见的脱脂工艺有：有机溶剂脱脂、化学脱脂、电化学脱脂、超声波脱脂。除有机溶剂脱脂外，其它脱脂工艺中由于含碱性物质、表面活性剂、缓蚀剂等组成的脱脂剂，废水中主要的污染物为pH、SS、COD、BOD、石油类、色度等。 The non-degreasing process is: organic solvents degrease, chemical degreasing, electrochemical degreasing, ultrasonic degreasing. In addition to the organic solvent degreasing, other degreasing process due to containing alkali, surfactant degreasing agent, corrosion inhibitor, etc, of the main pollutants in waste water for pH, SS, COD, BOD, petroleum, chromaticity and so on. 一般可以参考以下处理工艺进行处理：废水→隔油池→调节池→气浮设备→厌氧或水解酸化→好氧生化→沉淀→过滤或吸附→排放 General can refer to the following process for processing: waste water to separate oil pool, adjust the pool - air flotation equipment - anaerobic or hydrolysis acidification and aerobic biochemical to precipitate, filter or adsorption and emission 该类废水一般含有乳化油，在进行气浮前应投加CaCl2破乳剂，将乳化油破除，有利于用气浮设备去除。 This kind of waste water usually contains emulsified oil, should be in the gas float before the gas float the lacing agent, the emulsified oil is broken, be helpful to use gas float equipment to remove. 当废水中COD浓度高时，可先采用厌氧生化处理，如不高，则可只采用好氧生化处理。 When the concentration of COD in wastewater is high, the anaerobic biochemical treatment, if not high, can only be treated with aerobic biochemical treatment. |
