Embodiment 1

[0021] A method for the comprehensive application and treatment of heavy metal ion wastewater, comprising the following steps,

[0022] a. Pump the water body into the first sedimentation tank, the first sedimentation tank is provided with an oxygen supply pump, 2 grams of grease dispersant are sprinkled in every ton of water in the first sedimentation tank, and 1 floating wooden fence is set per ton of water body , the lower end of the floating wood fence is provided with a filter screen, and 1 kilogram of charcoal and rice husk activated carbon are laid on the filter screen in each floating wood fence to add up to 1 kilogram, 3 grams of dried orange peel, and 10 grams of microbial bacterial agent are sprinkled on the dried orange peel;

[0023] The preparation method of the microbial inoculum is as follows: 1 mass part of EM strain powder is added with 9 mass parts of water, 1 mass part of sugar, and 1 mass part of tangerine peel, fermented in the open air at 30-40 degrees Ce...

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.

Description

(1) Technical field [0001] The invention relates to a method for comprehensive application and treatment of water, in particular to a method for comprehensive application and treatment of heavy metal ion wastewater. (2) Background technology [0002] The use of microorganisms to treat sewage is the main direction of the environmental protection industry in the future. The mechanism of action is dominated by photosynthetic bacteria, yeasts, and actinomycetes, and cooperates with other beneficial microorganisms to produce antioxidant substances. Through oxidation-reduction fermentation, etc., Transform harmful and toxic sewage into harmless and non-toxic clean water, turning harmful into useful. [0003] Heavy metal ion wastewater contains a large amount of hexavalent chromium ions, lead ions, mercury ions, ferric ions, copper ions, etc., but there is no microbial community that has special effects on heavy metal ion wastewater in the existing biological fermentation methods, ...
