In the biological treatment, anaerobic biological treatment is used to reduce selenate ions and/or selenite ions presented in the raw wastewater to transfer to single insoluble selenium.

在生物法中，采用厌氧生物处理来降低原始废液中可溶的硒酸盐与亚硒酸盐，并转化为不溶性的单质硒，从而以不溶性单质硒的形式去除硒酸盐或亚硒酸盐；在絮凝沉淀法中，通常是向生物处理后的废水中加入一种金属盐，使该金属盐与可溶性硒反应并生成一种不溶性硒化合物，从而以不溶性硒化合物形式去除残留的可溶性硒；在过滤法中，将絮凝沉淀法中残留在废水中的不溶性硒去除，这样就能在不用大量化学药剂和不产生大量沉淀的情况下去除含硒废水中的可溶性硒。
