The preparation method of described fermentative processing agent is:

A, get 100 parts, mud at the bottom of pond and mix with 150 parts, water, filter, get filtered liquid;

B, by the filtered liquid sodium hydroxide solution in step (1), regulate pH be 7.5, solution stirring is even;

C, 55 parts, the solution obtained in step (2) and diatomite, humic acids 5 parts, poly-ferric chloride 3 parts, Ferrous Gluconate 3.5 parts, montmorillonite powder 25 parts, 3 parts, alum to be stirred after mixing, control material moisture content, make material water ratio be 35%-45%, to obtain final product.

Knit and stain water treatment steps and comprise:

(1) sewage is placed in the first mixing reactor, adds Sodium Pyrosulfite, stir 15min, Sodium Pyrosulfite add-on is the 3.5-8.6% of sewage quality;

(2) sewage after step (1) being processed is placed in the second mixing reactor, uses sodium hydroxide to regulate pH to 7.5, adds the polymerize aluminum chloride of sewage quality 2.5-3.5%, mix, filter after 20min, obtain filtrate;

(3) filtrate that step (2) obtains is placed in fermentation reaction cylinder, in fermentation reaction cylinder, adds the fermentative processing agent of filtrate quality 5%, fermentative processing more than 12 hours;

(4) filtrate after fermentative processing in step (3) is placed in coagulating cylinder, add magnetic kind and polyacrylamide, polyacrylamide add-on is the 4.5-7% of filtrate quality, and the mass ratio of magnetic kind and polyacrylamide is 2:3, abundant mixing, solidifyingly wads a quilt with cotton into mud mixture;

(5) then utilize disk to carry out Magneto separate to the mud mixture in step (4), make mud-water separation.

The invention has the beneficial effects as follows:

The present invention is used for staining water process knitting, and to the good degrading effect of pollutent, be separated thoroughly, and cost is low, the equipment of use is few, takes up room little; Solidifying wadding is adopted to process and use fermentative processing agent to carry out biological fermentation degraded; Adopt the technology of magnetic disc separation, make full use of the energy in high energy physics magnetic field, there is lower energy consumption, higher efficiency.The microbe species of fermentative processing agent enriches, and to the Degradation of various pollutent more comprehensively, has good decolouring, removes the function of SS, COD, heavy metal.
