摘要
本文通过分析污泥中重金属的含量及存在形态,探讨了厌氧消化过程中重金属的形态转化极其去除方法。结果表明生物稳定法和药剂稳定法是目前最有效的方法。不但可降低污泥中重金属的生物有效性,而且不影响污泥农用化。
The paper evaluates the form transformation and removal methods of heavy metals during sludge anaerobic digestion by analy -zing the total contents and patterns of heavy metals in sludge .The results showed that the biologic treatment and chemical stabilization can effectively remove the heavy metals in sludge .Not only reduce the bioavailability of heavy metals in sewage sludge , and does not affect sludge.
