Description
Technical field
The utility model is related to water purifying technical field, more particularly to a kind of wadding nuclear device improved and by its ginseng
With the water treatment system of structure.
Background technology
The flocculation basin for completing flocculation process, occupies important position status in clean water treatment.Suspended matter in natural water
The grain size of matter and colloidal substance is very tiny, in order to remove these substances, generally by means of the means of coagulation, i.e., adds in raw water
Enter coagulant appropriate, by fully mixing, colloidal stability is made to destroy（It is de- steady）And the polymer phase after being hydrolyzed with coagulant
Absorption makes particle have flocculating property.And the purpose of flocculation basin be exactly create suitable hydraulics make it is this have flocculability
The particle of energy is assembled in contacting with each other, to form larger floccule body.
Notification number is that the Chinese utility model patent of CN203222507U discloses a kind of wadding nuclear device, including hollow upper
Small stage body, the upper shell being connected with stage body upper end and the lower shell being connected with stage body lower end, lower shell are connected with into water under big
Pipe and blow-off pipe, upper shell are connected with outlet pipe, and the junction of stage body and lower shell is internally provided with grid, is loaded inside stage body
There is filler.Raw water initially enters lower cylinder by water inlet pipe, and then flows up in the wadding nuclear cavity in stage body, by wadding a quilt with cotton
When filler in nuclear cavity, countless tiny flows are formed, not only increase the area of reaction, and meet turbulent flow appropriate
Intensity, to strengthen the collision probability between wadding core nucleus；Meanwhile in the wadding nuclear cavity of up big and down small cone, in flow
The speed risen realizes that the particle in flow is fully assembled and forms wadding nucleome, then by upper cylinder by being discharged by slowing down soon
Pipe is discharged, into subsequent flocculation or precipitation process process.
The flocculating effect of above-mentioned flocculation plant is good, and wadding core speed is fast, is placed on flocculation basin front end, enters flocculation basin in raw water
It before flocculation, can fully mix, and reinforce flocculate collision probability, formed preferable with suspended matter in flocculation plant Chinese medicine
Flocculate nucleus, lays a good foundation for subsequent flocculation, but this flocculation plant is only suitable for the few raw water of sand content, for
The high raw water of sand content needs to increase preformed precipitate pond, and to remove the big sand grains of grain size in raw water, the floor space in preformed precipitate pond is thrown
Money is larger, substantially increases the cost of water purification.
