Abstract

The invention discloses a method for comprehensive application treatment of heavy metal ion wastewater. A first settling pond for microorganism treatment is arranged, and the first settling pond is communicated with a cooling tank of a plastic extruder. The method has the advantages as follows: 1, the specially-made microbial flora namely specially-made EM (effective microorganism) bacterial flora are adopted, chaff activated carbon and wood charcoal are adopted as bacteria beds, the contact area of the bacteria beds and a water body is large, and the heavy metal ions can be effectively adsorbed; 2, afterheat of cooling water of the plastic extruder is adopted, the microorganism treatment can be kept under the proper environment of 30-40 DEG C all the time when an energy source is saved, and the heavy metal ions in the water body can be adsorbed to the maximal extent; 3, a water pump continuously carries out cold and hot flow circulation on the cooling water of the plastic extruder and water inside the first settling pond, so that macromolecular organic matters in the water body can be evenly adsorbed by the wood charcoal and the chaff activated carbon in a floating wood fence to be supplied to the specially-made EM bacterial flora for growth and propagation.
