Description
Technical field
The present invention relates to a kind of water-purifying process, and in particular to a kind of quadratic micro-flocculation intensive filtration water-purifying process belongs to net
Water technical field.
Background technology
Tiny flocculation refers in the muddy water containing suspended particulate, and the wadding of small aggregation is formed by adding in flocculant
Solidifying process；Filter type in connection has contact filtration and directly filtering；Contact filtration and directly filter that difference lies in connect
Tactile filtering is to immediately enter filter tank after adding in flocculant in water, i.e., all moves in filter tank flocculation reaction process and carry out；Directly
Filtering flocculation basin is then set before filter, i.e., flocculation reaction part is placed in flocculation reactor and carried out, partly move in filter tank into
Row；Quadratic micro-flocculation intensive filtration technique belongs to microflocculation-filtration scope, refers to after sedimentation basin water outlet, treats that drainage enters
Before filter tank, tiny flocculation pond is set, adds flocculant, forms small and dense real tiny flocculation body, this tiny flocculation body can be to pass through filter
Bed of material surface, enters among filtering layer, makes deeper filtrate that can also adsorb, retains and receive dirt, so as to improve the retaining power in filter tank；
Its mechanism of action is that flco current potential enters filtering layer when reaching peak, makes the compression diffusion originally in flocculation basin in filtering layer
Middle progress；Since particle has larger affinity between filter bed, once current potential reduces, particle just coagulates rapidly in filter material layer
Poly-, the suction between particle starts to play a role, and attraction reaches maximum when current potential is close to zero, takes off steady particle and mutually adsorbs wadding
It coagulates and is constantly retained by filtrate and removed；This process progressively carries out on filtrate surface layer to deep, so as to play section dirty energy of filter material layer
Power achievees the purpose that length filter cycle, good filtration effect.
The content of the invention
To solve the above problems, the present invention proposes a kind of quadratic micro-flocculation intensive filtration water-purifying process, have take up little area,
Intensive degree height, low cost, the advantages of saving water and energy, have certain for the water plant design using micro- pollution lake, storehouse raw water
Reference value.
The quadratic micro-flocculation intensive filtration water-purifying process of the present invention, includes the following steps：
The first step, compound pre-oxidation by adding potassium permanganate and lime, and combine adding for coagulant in water-purifying process, group
Into compound preoxidation technique, algae is removed；
A. potassium permanganate is added, by the mixing in long range muddy water pipeline, raw water is pre-oxidized, so as to handle micro- pollution
Water source and control algae, while reduce the dosage of coagulant and chlorine；
B. basicity and flocculation core in water are increased by feeding lime, plays Coagulation aiding；Lime also have deodorization, sterilization,
Except color and remove the work of micro poisonous substance and the dephosphorization such as arsenic, cyanide, surfactant and raising ductwork water quality stability in water removal
With；
Second step, folded plate flocculation horizontal sedimentation tank precipitation, using folded plate flocculation rectangular sedimentation tank, centre sets passageway and leads to
Filter tank；It is divided into three sections by flow velocity by opposed flap, parallel folded plate, parallel straight panel in flocculation basin, every section of velocity gradient value is respectively
90. 32、42. 85、15.74s-1；Sedimentation basin is catchmented using perforation water distribution tracery wall water distribution, water outlet using sawtooth weir effluent trough, and
Using two hydrocone type machinery suction dredge spoil disposals；
3rd step, tiny flocculation pond flocculation, sets tiny flocculation pond between sedimentation basin and filter tank at the connection canal of both sides；During except algae
Tiny flocculation pond adds filter aid, using the stronger adsorption bridging characteristic of polymer substance, forms coarse closely knit flco；
4th step, air-water backwash filter filtering, using homogeneous filtering material gas-water backwash filtration, and on the total canal of filter tank piping lane water outlet
The reserved position for installing UV sterilizer additional；
5th step reserves advanced treating, and reserved depth is handled by ozone or activated carbon；
6th step, liquid chlorine disinfection.
Further, the filter aid in the 3rd step is polypropylene phthalein amine.
The present invention compared with prior art, quadratic micro-flocculation intensive filtration water-purifying process of the invention, have take up little area,
Intensive degree height, low cost, the advantages of saving water and energy, have certain for the water plant design using micro- pollution lake, storehouse raw water
Reference value.
