Technical field
The invention discloses a kind of water treatment additive, particularly a kind of water treatment flocculant.
Background technology
Flocculation agent mainly is just to have (bearing) electrical group to neutralize and have some particles that negative (just) electrically be difficult to separate in some water or be particle, reduce its electromotive force, it is played pendulum, and utilize its aggregation property to make these particles concentrate, and separate by physics or chemical process.Be generally the medicament that reaches this purpose and use, be referred to as flocculation agent.Flocculation agent is mainly used in feedwater and sewage treatment area.The chemical agent coagulating sedimentation is the method for generally using in the water technology.This method has less investment, takes up an area of little, characteristics such as working cost is low, wide adaptability.In the water treatment coagulating sedimentation, relate to flocculation agent feed intake opportunity, feed intake environment control, charging capacity, stimulation effect etc. widely, to reach suitable flocculating effect, satisfy the requirement to water treatment.The dyeing waste water complicated component, colourity is big, the concentration height, hard-degraded substance is many, and the COD value is high, and water quality is changeable, the main difficult point of handling such waste water is decolouring, adopt flucculation process treatment of dyeing and printing medicament commonly used based on inorganic aluminate, molysite at present, but these materials are relatively poor to the decolorizing effect of reactive dyestuffs, matching stain etc., are difficult to reach actual environment and administer requirement.
Summary of the invention
For addressing the above problem, the invention discloses a kind of water treatment flocculant, form simple, raw material sources are extensive, with low cost, to produce easy to usely, charging capacity is little, stimulation effect is good, flocculating effect is good, can efficiently generate gel flocculation deposition, thereby can reduce the flocculating and purifying cost effectively, improve the utilization ratio of water treatment efficiency and flocculation agent, be conducive to reduce the cost of water treatment.
For achieving the above object, the method that the present invention adopts is: a kind of water treatment flocculant, and composed of the following components: the aluminum contained compound of 15-30 weight part, the ironic citrate of 15-20 weight part, the bodied ferric sulfate of 5-8 weight part, the Na2Fe04 of 3-5 weight part; The polymerize aluminum chloride of 5-10 weight part, the non-ionic polyacrylamide of 10-15 weight part, 5-10 weight part polyamine compounds, and expanded perlite micro mist and the flyash micro mist mixture of 3-5 weight part; When described flocculation agent is 1g/l in usage quantity, be 97%-99% to the COD value for the percent of decolourization of the soil mud draining of 300-400mg/l, the COD clearance is 85%-89%, and the BOD clearance is 73%-76%, and total tp removal rate is 93%-95%, and total ammonia clearance is 44%-47%.
As a kind of improvement of the present invention, the granularity of described expanded perlite micro mist is the 200-300 order.
As a kind of improvement of the present invention, described flocculation agent activating component is the combination of described expanded perlite micro mist and flyash micro mist, and the weight ratio scope of expanded perlite micro mist and flyash micro mist is 3:2-5:3.
As a kind of improvement of the present invention, described polyamine compounds is a kind of in quadrol, the butanediamine or two kinds.
The invention has the beneficial effects as follows:
Flocculation agent disclosed by the invention, raw material sources are extensive, low production cost, charging capacity is little, the flocculation stimulation effect is good, and flocculation treatment is with low cost, and moisture resistance has good quality stability well simultaneously, long quality-guarantee period has good adaptive faculty to physical environment, and is easy to use.
Compound increases the flocculating agent molecule amount in the polyamines by introducing, and its viscosity is increased, and good stability is convenient to industrial production, and it is fast to have a sedimentation, characteristics such as good decolorizing effect.
By in flocculation agent, having added the flocculation agent activating component that is selected from a kind of or two combinations, the 3-5 weight part in expanded perlite micro mist and the flyash micro mist, not only improved the nucleation performance of stimulation effect and the gel of flocculation agent effectively, be conducive to reduce charging capacity, promote water treatment capacity, can regulate simultaneously the proportion of flocculation jello, increase the deposition capability of flocculation agent gel, thereby promoted the water treatment effect, reduce secondary pollution, improved the quality of handling water.
