电镀废水中的重金属抑制厌氧淀粉降解颗粒污泥的比产甲烷活性。当每克生物质分别与105 mg锌、120 mg镍、180 mg铜、310 mg铬或>400 mg镉接触时，颗粒对淀粉降解的SMA降低50%。颗粒污泥由于具有层状结构，比絮状污泥具有更高的抗毒性。
Heavy metals in electroplating effluent inhibited specific methanogenic activity (SMA) of anaerobic starch-degrading granules. The SMA of granules on the degradation of starch were reduced by 50% when each gram of biomass was in contact individually with 105 mg of zinc, 120 mg of nickel, 180 mg of copper, 310 mg of chromium, or >400 mg of cadmium. Granules had higher toxicity-resistance than flocculent sludge, due to their layered structure.
