Description
Technical field
The utility model is related to technical field of waste water processing, more particularly to a kind of reverse osmosis equipment for pre-processing negative pressure.
Background technology
Sewage, is often referred to discharge water necessarily polluted, from life and production.It is dirty according to the viewpoint of sewage source
Water can be defined as from the discharge of house, office, business or industrial area and underground water.The mixing such as surface water, snowstorm are taken
Liquid or water with waste.Sewage reduced by many classifications, correspondingly influence of the sewage to environment also have many technologies and
Technique.According to sewage source, sewage can be divided into this four class.The first kind：Industrial wastewater is lived from manufacture mining and industrial production
Dynamic sewage, including from the runoff live leachate stored, processed with industry or business, and other is not sanitary sewage
Waste water.Equations of The Second Kind：Sanitary sewage is from house, office building, machine-operated or similar sewage；Hygienic sewage；Effluent sewerage, bag
Include the industrial wastewater mixed in sewerage system in sanitary sewage.3rd class：Business sewage from commercial facility and also it is some into
Divide nontoxic, the harmless sewage more than sanitary sewage.Such as sewage from catering business.Sewage of wash house, animal feeding sewage, what hairdressing place produced
Sewage etc..4th class：Overland flow comes from water under rainwater, snow-broth, highway, the water from city and industrial area etc.,
Overland flow does not infilter soil, enters underground water along street and land.
In existing sewage reverse osmosis treatment equipment, the air in pretreatment stage in buffer tank is arranged by passage
Go out, be not closed, so foreign matter also can enter buffer tank by passage because buffer tank is provided with passage
In, so as to produce pollution；Existing reverse osmosis equipment cleaning capacity is poor, it is impossible to avoid pollutant from entering in counter-infiltration system, shadow
Treatment effect is rung, in addition, when producing negative pressure in due to insufficient water, pretreatment system, often causing pre-processing device quilt
Inhale it is flat, cause damage the problem of.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of reverse osmosis equipment for pre-processing negative pressure, for gram
Take prior art presence seal is poor, the easy blocking pollution of pipeline, can not solve the technology of generation negative pressure in pretreatment system
Problem.
The purpose of this utility model is achieved through the following technical solutions：
A kind of reverse osmosis equipment for pre-processing negative pressure, including pretreatment system and counter-infiltration system, the pretreatment system
System is included by the stainless steel pipes successively raw water box of sequential communication, raw water pump, more medium filter and active carbon filter, its
Described in raw water box top be provided with inlet channel, close to the active carbon filter water side pipeline on install one
Check-valves；The counter-infiltration system includes reverse osmosis unit and buffer, and the water side of the counter-infiltration system is provided with pure water tank,
Flow detector is installed on the inlet channel and counter-infiltration system.
Further, scale inhibition chemicals dosing plant, precision are also connected with turn between the pretreatment system and counter-infiltration system
Filter and high-pressure pump.
It is preferred that, the pipe between the scale inhibition chemicals dosing plant, accurate filter, high-pressure pump, counter-infiltration system and pure water tank
Multiple valves are provided with road.
Further, it also is provided with flow detector on the pipeline between the accurate filter and high-pressure pump.
Compared with prior art, the utility model at least has advantages below：
By above-mentioned the technical solution of the utility model, without using buffer tank of the prior art, hindered by setting
Dirty chemicals dosing plant, using hermetic design, it is to avoid sewage enters counter-infiltration system, and is conveniently cleaned to pipeline, makes pipeline not
Easy blocking pollution, improves the effect of water process；On the other hand, pacify before counter-infiltration system pipeline is entered after pretreatment is completed
A check-valves is filled, when equipment is normally run, has certain pressure, check-valves is by hydraulic pressure jack-up, when the dirty stifled output of pretreatment
When not enough, check-valves sucks air by counter-infiltration main frame high-pressure pump, it is therefore prevented that due to insufficient water, produces and locates in advance caused by negative pressure
Reason equipment by inhale it is flat, cause damage, the service life of extension device.
Brief description of the drawings
Fig. 1 is a kind of attachment structure signal for reverse osmosis equipment for pre-processing negative pressure that the utility model embodiment is provided
Figure.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out clearly and completely
