Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A kind of adjustable micro-flocculation clarifier, described depositing reservoir comprises tiny flocculation reaction zone 1 and settling zone 6, and described settling zone 6 is provided with inclined-pipe settler.
Tiny flocculation reaction zone 1 is in the present invention provided with the flashboard in adjustable reaction time, can, according to the turbidity size adjustment reaction time, while guarantee fully reaction, the flco of generation can not be made again because the reaction time is long to precipitate in reaction tank.
In the present invention, depositing reservoir adopts circular, and the periphery of circular depositing reservoir is provided with water inlet 9 and delivery port 10, adopts the water intake mode of circumferential water feed, its water inlet current are more close to center, and flow velocity is larger, then hydraulic radius is less, Froude number is larger, and the stability of current is become better and better; Adopt circumferential water feed, peripheral effluent, can improve the surface loading in pond, makes surface loading reach 9m3/ (m2.h), and the mistake flow rate of depositing reservoir can be made to reach 36m
3/ (m
2.h), improve the disposal ability of depositing reservoir, its fluidised form can adapt to the density current fluidised form caused by Inlet and outlet water concentration of suspension difference, avoid the harmful effect such as various short stream, circulation caused by density current, volumetric efficiency is high, and water intake mode is flexible in addition, ensures the outlet effect when different influent quality, save energy consumption, improve treatment effeciency.
The course of work of adjustable micro-flocculation clarifier is:
(1), after former water adds PAC, through pipe-line mixer mixing, tiny flocculation reaction zone 1 is entered.Tiny flocculation reaction zone 1 is provided with the flashboard in adjustable reaction time, and the reaction time is between 30min-15min.Summer water temperature higher, when turbidity is larger, the adjustable reaction time at 15min, to ensure that abundant reaction can not make again the flco of generation precipitate in reaction tank because the reaction time is long; In the winter time during low-temperature and low turbidity, can the proper extension reaction time, to ensure fully to react in flocculation reaction district.
(2) carry out abundant reacted water at tiny flocculation reaction zone 1 and enter guiding region 2.Because this discharge area, district is large, therefore defluent flow velocity is less, to sinking mud at the bottom of pond without impact phenomenon.
(3) water flowing through guiding region 2 enters water distributing area 3 from perforation water distribution wall.Water can form backflow in water distributing area 3, can impel the further flocculation of de-steady colloid in water, accelerate the precipitation of settling zone 6;
(4) water evenly enters settling zone 6 through water distributing area 3.Water is carry out in accordance with shallow-layer tube settling mechanism in the centrifugation of this part.Under the condition that sedimentation basin dischargeable capacity is certain, inclined-pipe settler can increase the desilting area of settling zone 6, thus greatly can improve the treatment effeciency of depositing reservoir; The hydraulic radius of settling zone 6 reduces greatly, and current are essentially laminar condition, meets the stability of water and the requirement of laminar flow.
(5) former water enters clear water zone 4 via behind settling zone 6, and clear water zone 4 turbidity is less than 10NTU, and clear water zone 4 water outlet directly enters filtration plant and carries out filtration treatment.
(6) bottom, water distributing area 3 is sludge discharging area.Sludge discharging area is divided into mud collection area 7 and bucket 5.Alumen ustum accumulates mud and concentrates in mud collection area, depositing reservoir bottom 7, mud collection area 7 sinks mud after bucket 5 scraped by center driving suspension mud scraper, adopts the mode of gravity spoil disposal to discharge and is discharged by discharge pipeline 8.
In sum, invention increases the disposal ability of depositing reservoir, thus greatly can shorten the sedimentation time; Increase the desilting area of depositing reservoir, thus greatly can improve treatment effeciency.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
