Description
Technical field
The invention belongs to water-treatment technology fields, and in particular to a kind of composite flocculation agent and its application.
Background technique
Wastewater treatment is a multistage process, since filtering out big object, is carried out in second stage to water clear
Clearly.Specific water to be processed and required water quality are depended on the next stage.The pollutant that these stages are capable of handling is mostly
Suspended contaminant, and a small amount of dissolved contaminants removed by clarifying process.
Clarification is realized by using the chemical substance of referred to as flocculant, this makes to this flocculant or clarifying agent
Foundation reference it is very universal.Flocculation process itself is related to the presence of the charge species such as ion, and wherein charge is higher, and force of flocculation is got over
By force.Once flocculation is completed, treated water will enter precipitation process, in this process, floccule body precipitating and and moisture
From.Process efficiency depends on the physical chemistry and mechanical performance of floccule body, that is to say, that low-density floccule body or " spongy " wadding
The settling efficiency of solidifying body is lower than fine and close floccule body.In addition, this group is that a kind of particle or one group of particle, their behavior are originated from
In being integrated into chemical substance together, because before treatment, charge can be such that pollutant stays in water.
The clarification of water, most commonly aluminum sulfate were realized using multiple compounds in the past.This chemicals have technology,
Business and advantage economically.It is one of most widely used product in water process, because it has low health and environment
Risk and commercial applicability.
Removal and mistake of the aluminum sulfate with its different form of expression (anhydrous, single water or more water) for suspended solid in water
Adjuvant is filtered, strainability is improved.The dosage of aluminum sulfate needed for wastewater treatment can be higher than 2 kilograms every cubic metre.Institute as above
It states, in most of filter process, aluminum sulfate can increase the removal of suspended solid as filtering agent, molten without removing
The heavy metal or organic compound of solution.
Polymer has been developed to substitute the use of aluminum sulfate；Polymer volume is than aluminum sulfate much less.These polymerizations
Object is the high molecular weight organic chain with different functional groups, mainly ionic or cationic or anionic.Therefore they
Sometimes referred to as polyelectrolyte.The validity of polymer derives from many functional groups.Have on thousands of due to synthesizing a kind of polymer
Ten thousand kinds of different precursors (monomer), so the amount of polymer that can actually be synthesized is unlimited.However, flowing to water flow from water
Change procedure in, how to obtain optimal polymer is an extremely difficult problem.
In the polymer not occurred using inorganic flocculating agent, there is also pH and temperature sensitivity high, dosage and mixing
Equipment influences the technical problems such as big.Polymer be usually it is powdered, be formulated in use site with water because it be easy very
Fast failure.Polymer flocculation body is generally intolerant to turbulent flow, and when encountering technical problem, pollutant is returned in water.
Therefore, the good composite flocculation agent of the easy to use and clarifying effect of one kind and its application are needed.
