Description

Integration washed-out sand wastewater recycling device
Technical field
The invention belongs to wastewater treatment and resource utilization field, the integrated washed-out sand wastewater recycling device being specifically related in washed-out sand field mud waste water process technology and reusing sewage equipment.
Background technology
The materials of man-made sand system of processing of current China, major part adopts wet process technique, general classification and the cleaning adopting screw classifier to carry out fine sand. The maximum shortcoming of the method is exactly that water consumption is big, in waste water containing a large amount of silt, it is generally that battle field water consumption per hour is up to about 300 tons concerning the husky industry of system, that is the mud that can produce more than 300 ton per hour, if directly discharge not only pollutes the environment, river course also can be caused to block. A lot of battle field uses natural sedimentation method, several bigger settling tanks are built exactly by mud natural sedimentation in place, building settling tank to need to be that expense is not said and to be had enough places in a large number, the mud precipitated does not reach certain mass dryness fraction, and dealing with also is a very thorny thing.
Summary of the invention
The present invention is on the mud-water separation Process ba-sis such as existing heavy sand and precipitation, for single heavy sand process can only segregation ratio great in the grains of sand of 1, proportion close to the mud mud-water separation weak effect of water, a kind of integration washed-out sand wastewater recycling device that centrifugal heavy sand, tube settling, flocculation reaction and Automated condtrol are organically combined and propose by the feature of single settling tank mud-water separation sedimentation time length. The implication of SWWR is Sandwashingwastewaterreuse, i.e. washed-out sand wastewater recycling device. Its core process is enter centrifugal heavy sand unit after utilizing the turbulent fluidised form of pipeline to be mixed by flocculation agent and utilize two-stage precipitation to carry out mud-water separation, and the sewage after process reaches washing water quality standard in " urban sewage reutilization industry water standard " (GB/T19923-2005).
For achieving the above object, the present invention adopts following technical scheme:
Integration washed-out sand wastewater recycling device, comprising:
Flocculation dosing pond, is provided with pump in described flocculation dosing pond,
Rotational flow grit chamber, the side of described rotational flow grit chamber is provided with water-in and water outlet, and described rotational flow grit chamber is equipped with diversion mixing device for stirring waste water,
The bottom that the mouth of a river of described rotational flow grit chamber is connected in first stage precipitation tank by water pipe, the bottom that the spillway of first stage precipitation tank side top is connected in second-level settling pond by water pipe, the spillway of the side top of second-level settling pond connects outlet conduit,
The bottom of described rotational flow grit chamber, first stage precipitation tank, second-level settling pond is all connected to mud discharging pump by pipeline,
In flocculation dosing pond, the rising pipe of pump is connected with the water inlet pipe of rotational flow grit chamber,
The water inlet pipe of described rotational flow grit chamber is provided with ejector.
In technique scheme, described rotational flow grit chamber comprises the dirty grit removal part of upper part of column construction and the lower part sand deposition hopper of taper structure
In technique scheme, described diversion mixing device is arranged on dirty grit removal part, and the described guide vane of diversion mixing device and the top of sand deposition hopper are put down together.
In technique scheme, the water-in of described inlet channel is arranged on the tangent position in rotational flow grit chamber.
In technique scheme, the diameter of the water outlet of described rotational flow grit chamber is the twice of inlet channel.
In technique scheme, in described first stage precipitation tank and second-level settling pond, it is provided with some inclined tube fillers.
In technique scheme, the high-strength corrosion-resisting particular fillers that described inclined tube filler adopts the compacting of Q235 steel matter and becomes.
In technique scheme, described inclined tube filler becomes 60 degree to be inclined in first stage precipitation tank and second-level settling pond.
In the present invention, adopting integrated arrangement form between rotational flow grit chamber, first stage precipitation tank, second-level settling pond, flocculant concentration pond and control, compared with single precipitation or heavy sand technique, its technical superiority is mainly reflected in:
(1) the mud-water separation time is short, and occupation area of equipment is little. Because washed-out sand waste water water consumption is greatly, it is long to there is the required residence time in the single heavy sand of tradition or depositing technology, and floor space is big waits deficiency. The present invention is in the same water yield washed-out sand waste water situation of process, and floor space is only about the 1/20-1/10 of tradition settling tank floor space.
(2) effluent quality is good. Sewage after process reaches washing water quality standard in " urban sewage reutilization industry water standard " (GB/T19923-2005).
(3) working cost is low. Its main operating expenses is embodied in electricity consumption and medicament two aspects. Ton water treatment expense of the present invention is below 0.8 yuan/ton of water.
(4) construction cost is low, processes its useful volume of the same water yield little. Owing to reducing occupation area of equipment and space, therefore construction cost is far below tradition depositing technology.
