The China's coal-mine major part is in the area of lack of water, and the reclamation of mine water utilization has become the main path that solves the mine water resource shortage.At present, domestic mine water desalting processing mainly adopts the reverse osmosis deaslination treatment process.For guaranteeing counter-infiltration system long-term stability, reliability service, the preliminary treatment of counter-infiltration system is very important.The preliminary treatment of counter-infiltration system must be satisfied the water quality requirement of feed water by reverse osmosis, i.e. turbidity<0.3NTU, pollution index FI value<4.Pretreated main purpose is to remove suspension, turbidity, colourity, organic matter etc.If do not remove these materials, can accumulate in the film surface film is polluted, and separate out with solid form, film properties is degenerated.Finally cause the permeability rate and the salt rejection rate of film to descend, influence aquifer yield and water quality.
The pretreating process of present domestic coal mine water reverse osmosis deaslination adopts traditional more medium filter, active carbon filter, accurate filter and security personnel's filter level Four to filter.This complex treatment process, poor processing effect, and bulky, complicated operation, labour intensity is big, is difficult to adapt to the development level of present China's coal-mine.
The utility model content
The purpose of this utility model one provides a kind of pretreatment unit of mine water desalination, makes that the pretreating process of reverse osmosis deaslination is simpler, treatment effect better, the volume of reduction means.
The purpose of this utility model two provides a kind of reverse osmosis deaslination equipment, makes the desalination pretreating process more simplify, and desalting effect is better.
In order to realize purpose one, the utility model provides a kind of pretreatment unit of mine water desalination, comprising: water pump, lamination filter and ultrafilter, described water pump, lamination filter are connected by pipeline successively with ultrafilter.
By above technical scheme as can be known: the pretreatment unit of the utility model mine water desalination, water pump, lamination filter and ultrafilter are formed a single unit system, have the following advantages: simplified pretreating process, finished the work by two kinds of filters; Treatment effect is good; Dwindled the cumulative volume of device, reduced requirement installing space; Simple to operate, reduced labourer's labour intensity.
In order to realize purpose two, the utility model also provides a kind of reverse osmosis deaslination equipment, the pretreatment unit, high-pressure pump and the Reverse Osmosis Desalination Process Equipment that comprise the mine water desalination, the delivery port of the pretreatment unit of described mine water desalination, high-pressure pump and Reverse Osmosis Desalination Process Equipment are connected successively by pipeline, the pretreatment unit of described mine water desalination, comprise: water pump, lamination filter and ultrafilter, described water pump, lamination filter are connected by pipeline successively with ultrafilter.
By above technical scheme as can be known: the utility model reverse osmosis deaslination equipment, by setting up the pretreatment unit of mine water desalination, can reduce the contaminated degree of reverse osmosis membrane, prevent that film from descending because of being subjected to polluting the permeability rate and the salt rejection rate that cause film.
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Description of drawings
Fig. 1 is the structural representation of the pretreatment unit of utility model mine water desalination;
Fig. 2 is the structural representation of utility model reverse osmosis deaslination equipment.
The specific embodiment
Embodiment one
As shown in Figure 1, the pretreatment unit of a kind of mine water desalination of embodiment of the present utility model comprises: water pump 1, lamination filter 2 and ultrafilter 3, described water pump 1, lamination filter 2 and ultrafilter 3 are connected successively by pipeline 5.
In concrete the application, water pump 1, lamination filter 2 and ultrafilter 3 are fixed in the same frame 4, by water pump 1 mine water is drawn in the pipeline 5.Mine water at first flows into lamination filter 2 by pipeline 5, removes suspensions such as the grains of sand, iron rust in the mine water by lamination filter 2, and reduces organic content in the mine water; Flow into ultrafilter 3 through lamination filter 2 treated waters by pipeline 5, by ultrafilter 3, materials such as bacterium, iron rust, colloid, larger molecular organics in the thorough filtering water, reservation is to the health beneficial trace elements, leading indicators such as the microorganism of purifying waste water, colourity and turbidity satisfy " GB5749-2006 drinking water sanitary standard " requirement.
By the mine water that the pretreatment unit of mine water desalination was handled, capacity of outlet water is 5~30t/h, and the water quality of water outlet can reach turbidity<0.3NTU, pollution index FI value<4, thus reach the preliminary treatment requirement of reverse osmosis desalinization system.
From technique scheme as can be seen, the pretreatment unit of a kind of mine water desalination of the utility model has following characteristics:
1, simplified pretreating process, treatment effect is good, has improved turbidity removal rate, pollution index FI value clearance and the water rate of recovery;
2, simple to operate, reduced labourer's labour intensity;
3, Zhuan Zhi cumulative volume is little, has reduced the requirement to installing space, and the manufacturing cost of complete equipment is descended.
Embodiment two
In described lamination filter 2, be provided with the full-automatic back washing controller.The full-automatic back washing controller under the situation of interruption of work, is not finished whole automatic backwash process in the several seconds.Automatically start backwash by the time differential pressure signal of setting, the backwash valve changes water (flow) direction in the filter element, and the impurity on the disc washes away in the lamination filter 2 with being trapped in.Reduced the workload that the staff clears up filter, reached and to reach better cleaning effect with self water consumption seldom.
