Abstract
The invention relates to a water treatment device, in particular to a drinking water filtering device which comprises an outer shell and a membrane component. The drinking water filtering device is characterized in that the outer shell of the device is a semi-closed circular cylinder, that is, one end is closed, and the other end is open; the outer shell is made of organic glass, the wall thickness is 5mm, the inside diameter is 75mm, and the length is 600mm; the ultrafiltration membrane is a bundling membrane, the size of the membrane component is that, the diameter is 75mm, the length is 586mm and the area of the membrane is 2m<2>; the ultrafiltration membrane is arranged in a cylindrical container of the outer shell, and the water outlet end of the membrane component just closes the other open end of the cylinder. Tap water permeates the membrane under the action of a free head after entering the container, and viruses, bacteria and other microbes are intercepted, thereby, the microbes are removed. Condensate can be regularly emitted, and the membrane component can be regularly cleaned by using sodium hypochlorite. The drinking water filtering device is used for the micro-pollution processing of a drinking water source.
Description
Technical field
The present invention relates to a kind of water treatment facilities, particularly relate to a kind of filtering apparatus for drinking water, the little pollution that is used for drinking water source is handled.
Background technology
Drinking water safety is to concern health and significant problem national economy, ensures drinking water safety, safeguards that people's healthy life is the primary need of current socio-economic development to water conservancy working.Yet running water dispatches from the factory the back long apart from course of conveying in, do not exceed standard in order to guarantee the terminal chlorine residue of pipe network, chlorinity reduces gradually in the pipe network, adds a small amount of organic matter residual in the running water, has caused growing of microorganism in the water distributing network; Also have hydropexis overlong time in the water storage equipment, chlorine residue easily disappears, and water quality easily changes, and causes microbial growth; The not on-call maintenance maintenance of water storage equipment does not have thorough cleaning and sterilizing, can grow microorganism yet; Sometimes the long-term stasis of tip water also can produce colored water, Ru Hongshui, brown water, clear water etc.In use also there is pollution problem at water dispenser, water courage water too much and is not for a long time drunk, barreled drinking water total number of bacteria, mould and saccharomycete and the equal severe overweight of coliform that water dispenser cold water end flows out, the water dispenser microbiological indicator that has surpasses 10 times of state-set standard.
Because the quality requirement to drinking water is more and more stricter, water treatment company drops into the amount that increasing energy is controlled the microorganism that exists in the water supply network.In order to accomplish this point, therefore a kind of method is to carry out costliness, frequent water examination, perhaps prevents the barrier that bacterium and virus enter in the setting of water supply terminal.
Summary of the invention
The object of the present invention is to provide a kind of ultrafiltrationmembrane process treating apparatus at the drinking water secondary pollution.This device builds up such barrier very easily, can reach 6log to the clearance of bacterium, reaches 4log for the clearance of virus, and equally very high to the removal of colourity, the water user needn't worry bacterium and virus and color problem.
The objective of the invention is to be achieved through the following technical solutions:
A kind of filtering apparatus for drinking water includes shell and membrane module, and this crust of the device is semiclosed rounded cylindrical, i.e. end sealing, and the other end opens wide; Shell is that lucite is made wall thickness 5mm, inside diameter 75mm, long 600mm; Milipore filter is the film of getting one's things ready, and the membrane module size is diameter 75mm, and long 586mm, membrane area are 2m
2Hyperfiltration membrane assembly is placed in this shell cylindrical vessel the other end sealing that the membrane module water side is opened wide cylinder just.
Described a kind of filtering apparatus for drinking water, the mode of this device filtered water is: after the running water with free head enters container, under the free head effect, see through film, microorganisms such as virus, bacterium are trapped, thereby obtain the drinking water of the health that does not contain microorganism.
Described a kind of filtering apparatus for drinking water, this device water inlet and outlet pipe and delivery pipe place are equipped with butterfly valve, for stainless steel is made.
The invention has the beneficial effects as follows: can not contain bacterium, virus, colibacillary cleaning, free of contamination health water for the water user provides.And this device has the producing water ratio height, and is safe, and control easily, and is easy to operate, characteristics such as small investment.In order to allow the running water of water user's safe for drinking, health, health,
Description of drawings
Fig. 1 is the floor map of apparatus of the present invention.
Number in the figure: 1. water inlet; 2. container (shell); 3. hyperfiltration membrane assembly; 4. outlet pipe; 5. delivery pipe.
The specific embodiment
Adopt existing UF film system, can build up such barrier very easily.Milipore filter can reach 6log to the clearance of bacterium, reaches 4log for the clearance of virus, so water factory and water user needn't be in the problems of worrying bacterium and virus.Because the quality of drinking water itself is very high (turbidity and suspended solid are all very low) just, therefore the film system of this moment can adopt very high membrane flux, can reach 135 liters/square meter. hour.Simultaneously higher go into water condition, the frequency that therefore recoils and chemistry are strengthened the frequency of backwash can be very low, and aquifer yield can reach 99%.Can also set up the two-stage ultrafiltering system if desired, with the further reuse of the backwash water of the first order.
As Fig. 1, running water pipe is registered one's residence the back earlier through water inlet 1, enters container 2, sees through hyperfiltration membrane assembly 3 then, handles back water and inserts indoor sparge pipe through delivery port 4 again, and concentrate is regularly discharged by delivery pipe 5.Water inlet and outlet pipe and delivery pipe place are equipped with butterfly valve, all have stainless steel to make, and the water inlet diameter is 20mm, the delivery pipe diameter is 15mm, and it is lucite that diameter of outflow tube is made material for the 20mm. crust of the device, and thickness is 5mm, inside diameter 75mm, long 600mm.Milipore filter is the film of getting one's things ready, and the membrane module size is diameter 75mm, and long 586mm, membrane area are 2m
2
Because the quality of drinking water itself is very high (turbidity and suspended solid are all very low) just, therefore the film system of this moment can adopt very high membrane flux, can reach 140L/m
2.h.Simultaneously higher go into water condition, so the frequency of Chemical cleaning can be very low, aquifer yield can reach 99%.Cleaning agent can adopt the liquor natrii hypochloritis.
