Object, under the conditions of 25-30 DEG C, fermentation liquid made from 1:1 equal proportion mixing fermentation culture 4-6 days；
It advanced optimizes, the thickener is at least one of chitin and chitosan；
It is further preferred that the chelating agent is at least one of trehalose and borax；
It advanced optimizes, the enzyme stabilizers are at least one of glutamic acid and glycine.
Technical solution of the present invention additionally provides a kind of preparation method of biological enzyme flocculant, it is described the preparation method comprises the following steps:
According to mass parts, first the deionized water is added in water-bath, 60-70 DEG C is warming up to, thickener is added while stirring,
It is cooled to room temperature after mixing evenly, chelating agent is added, adjusting pH value after mixing evenly is 7.0-8.0, sequentially adds biological enzyme, enzyme
Stabilizer stirs evenly obtained biological enzyme flocculant.
The invention has the benefit that
Biological enzyme flocculant in the present invention can significantly reduce suspended matter, coloration in sewage etc.；Preparation process is simple, comes
Source is extensive, and preparation process does not generate secondary pollution；It can be used for handling sanitary sewage, city black and odorous water and industrial wastewater etc., make
Environment nonhazardous is acted on rear.In addition, this flocculant also have the characteristics that it is efficient, environmentally friendly, be widely used.
