Abstract
The invention discloses a kind of composite flocculation agents for handling desulfurization wastewater, including modified starch, modified maltodextrin, modification of chitosan, modified glucan, modification infusorial earth, modified kaolin, modified medical stone, modified serpentine, modified bubble stone, modified alta-mud；By inorganic and organically compound, play the strong point of different type and different structure flocculant, and overcome the defect of organically-modified compound and inorganic modified minerals inherently, and change morphosis and the distribution of polymer, inorganic mineral ingredient adsorbing contaminant and suspended particulates make to form particle and be gradually increased；And organic compound ingredient generates the net effect of catching using the active group being adsorbed on organic compound by the bridge linking effect of itself, net catches other impurity particles and sinks together.Meanwhile the presence of inorganic mineral neutralizes pollutant surface charge, promotes the flocculation of organic compound, greatly improves flocculating effect.
Description
Technical field
The present invention relates to a kind of sewage-treating agent, in particular to a kind of composite flocculation agent for handling desulfurization wastewater.
Background technique
China be based on coal resources based on carry out electric energy conversion big country, in the end of the year 2014, thermal power plant accounts for
The 70% of energy resource structure.Thermal power plant is used as with water, drains rich and influential family, accounts for 20% or more of industrial total amount with water.Wherein desulfurization wastewater
To be most complicated here, most intractable water.The waste water major pollutants are heavy metal, acid ion, chloride ion, suspended matter
Deng if direct emission can cause environment greatly to pollute.
Producing upper common method at present is that " three headers " needs to add five kinds of chemicals treatments, adds complexity, plant maintenance
It is cumbersome, and most cases cannot be up to standard.
Summary of the invention
In view of this, flocculating effect is good the purpose of the present invention is to provide a kind of composite flocculation agent for handling desulfurization wastewater,
Performance is stablized, and effectively removes the organic matter in water body, inorganic matter and heavy metal ion, reduces turbidity of sewage, improves at sewage
Manage efficiency.

It further, further include 0.3-0.5 parts of initiator；
Further, the initiator is azodiisobutyronitrile.
Beneficial effects of the present invention：The composite flocculation agent of processing desulfurization wastewater of the invention, by inorganic and organically multiple
It closes, plays the strong point of different type and different structure flocculant, and overcome organically-modified compound and inorganic modified minerals sheet
The intrinsic defect of body, and change morphosis and the distribution of polymer, inorganic mineral ingredient adsorbing contaminant and suspended particulates, make
It forms particle and is gradually increased；And organic compound ingredient is by the bridge linking effect of itself, using being adsorbed on organic compound
Active group generate the net effect of catching, net catches other impurity particles and sinks together.Meanwhile the presence of inorganic mineral makes pollutant
Surface charge neutralizes, and promotes the flocculation of organic compound, greatly improves flocculating effect.Flocculant of the invention is used to locate
Desulfurization wastewater is managed, the removal rate that the removal rate of suspended matter is 98%~99.9%, COD is 70%~85%, the removal of heavy metal
Rate is 97%~99.5%, and the removal rate of ammonia nitrogen removal frank is 20%~25%, SS, turbidity removal rate reaches 99% or more.
Specific embodiment
The composite flocculation agent of processing desulfurization wastewater of the invention, the flocculant raw material includes following components by weight：
