Abstract
The present invention discloses a composite flocculant for urban sewage treatment. The composite flocculant is characterized in that the composite flocculant is mainly prepared by respectively compounding diatom with a concentration of 70% and a polymeric iron oxide with a concentration of 40% according to a mass ratio of 80-90:10-20. The present invention further discloses a use method of the composite flocculant. According to the present invention, advantages of biological treatment and biochemical treatment can be concurrently provided by using the composite flocculant of the present invention, nitrogen, COD and other substances can be effectively removed, no secondary pollution can be generated, cost is low, a reagent effect is significant, and a decolorizing effect on water color is good.
Description
Technical field
The present invention relates to a kind of flocculation agent, specifically be a kind of in polymerization oxidation iron compound a kind of material, obtain having the composite flocculation agent of the municipal sewage treatment of sewage treatment capacity preferably.
Background technology
Along with development of city, the quantity discharged of municipal effluent reached must improvement stage.And to the improvement of municipal effluent, general what adopt is that water is purified, and removes or reduces compositions such as nitrogen, COD, BOD, SS, total phosphorus, then clear liquid is continued reuse.The result of this kind treatment process OK, depend mainly on the used flocculation agent of purifying waste water in fact.
Summary of the invention
Main contents of the present invention are to provide a kind of composite flocculation agent of municipal sewage treatment, specifically are that a kind of to have adsorptive power strong and can effectively reduce the composite flocculation agent of water body chroma.
In order to solve above technical problem, of the present invention a kind of be that 70% diatom and concentration are that 40% polymerization oxidation iron is composite respectively the making of ratio of 80-90:10-20 in mass ratio mainly by concentration.
The present invention also provides a kind of method of use of composite flocculation agent of municipal sewage treatment; It is characterized in that: pending waste water Ph value is transferred to 6-8; Input concentration is 70% diatom 80-90 mass parts earlier, stirs after 3-5 minute, and dropping into concentration again is 40% polymerization oxidation iron 10-20 mass parts; Stir leave standstill 8-12 hour after 20-30 minute after, isolate clear liquid.
The invention has the advantages that: adopt this flocculation agent, have the advantage of biological treatment and biochemical treatment concurrently, can effectively remove materials such as denitrification, COD, and can not produce secondary pollution.And cost is low, and the reagent effect is obvious, the water colour good decolorizing effect.
Embodiment
Form solution for later use in the zero(ppm) water that the zeyssatite and the 1 gram polymerization oxidation iron of 5 grams is dissolved in 0.5 liter respectively.
Select 1 liter of sewage, transfer pH value to 8, pour tripolite solution earlier into, stirred 5 minutes with acid.And then pour into
The polymerization oxidation ferrous solution, stir saw that the flocculation particle increased in 30 minutes after, left standstill 40 minutes.Measure, 9 minutes settling of floccus time, the percent of decolourization 96% of calculating, to the clearance about 75% of COD, the BOD clearance is about 80%, and about 90%, the place to go of total phosphorus is about 95 to the SS clearance, and ammonia nitrogen removal is 40%.
Claims (2)
1. the composite flocculation agent of a municipal sewage treatment is characterized in that: be that 70% diatom and concentration are that 40% polymerization oxidation iron is composite respectively the making of ratio of 80-90:10-20 in mass ratio by concentration mainly.
2. the method for use of the composite flocculation agent of a municipal sewage treatment; It is characterized in that: pending waste water Ph value is transferred to 6-8; Input concentration is 70% diatom 80-90 mass parts earlier, stirs after 3-5 minute, and dropping into concentration again is 40% polymerization oxidation iron 10-20 mass parts; Stir leave standstill 8-12 hour after 20-30 minute after, isolate clear liquid.
