Description

A kind of domestic sewage treatment unit

Technical field

The invention belongs to the waste disposal plant field, be specifically related to a kind of domestic sewage treatment unit.

Background technology

China is the country of a Freshwater resources serious lack, and along with the further quickening of rapid economic development and urbanization process since the reform and opening-up, the city water resource imbalance between supply and demand is further outstanding.China at present in nearly 700 cities lack of water up to more than 400, and nearly 100 city serious water shortages are arranged wherein.For solving shortage of water resources contradiction, must adopt continuable water resources to utilize pattern-saving type pattern.Except the water of advocating thriftiness, to open up outside the new water source, the regenerated using of sewage and waste water also is an important channel.

Sewage as the water source, is made miscellaneous water after suitably handling, between Shang Shui and following water, be called middle water between its water-quality guideline, corresponding techniques is called reused water technique.In water can be used for lavatory flushing, gardens and field irrigation, road are kept a public place clean, the additional water of carwash, city fountain, cooling apparatus etc.Technology of middle water recycle is applied to practice abroad already.State's lavatory flushing, gardens and field irrigation, roads such as the U.S., Japan, Israel are kept a public place clean, carwash, city fountain, cooling apparatus replenish water etc. all use in large quantities in water, accumulated many successful experience aspect the Zhong Shui utilizing.China from six or five, the Seventh Five-Year Plan just begin one's study the utilization of water, bring into use in late 1990s, formed certain scale at present, developing the use in industry and agricultural.

Summary of the invention

The invention discloses a kind of domestic sewage treatment unit, developed a cover and be applicable to the sewage reuse device that family uses, to technology of middle water recycle popularize and water saving subtracts dirty significant.

For realizing objects of the present invention, adopt following technical scheme:

1. a domestic sewage treatment unit is characterized in that comprising by water purification catridge and actuating unit two portions constituting; Water purification catridge is arranged at tank water outlet bottom, connect water pipe again after, connect actuating unit.

2. the described actuating unit of step 1 mainly is made up of middle water hopper, vacuum breaker, rising pipe, piston, piston rod, pin handle, spring, vacuum breaker; Wherein, water hopper during the water pipe of family expenses connects, the water outlet of hopper is flowed through through rising pipe and is discharged behind the vacuum breaker; Vacuum breaker is by the piston trip switch, and piston is connected with spring through piston rod; It is consistent that the open-circuit position of vacuum breaker and piston move down direction.

3. the described water purification catridge of step 1; It is to design according to the MULTIPLE COMPOSITE work principle of filter; It is 5 layers that filter core is divided into from top to bottom; Every layer filtration medium is all selected to the removal of certain pollutent, is respectively: coarse filtration layer, filter bed of essence, layer of fibers, granulated active carbon layer and rete.

4. the described coarse filtration layer of step 3, its material of selecting for use is a stainless steel mesh, and base plate can be opened circular hole or strip hole, and percentage of open area is bigger, and its major function is to hold back dish leaf, suspended substance that grain of rice equal-volume is bigger.

5. the described filter bed of essence of step 3, what it was selected for use is the fabric medium, like fine and close gauze etc., hole is very little, is used to hold back fine suspension such as hair, meat foam.

6. the described layer of fibers of step 3, what it was selected for use is the synthetic fiber through modification.

7. the described granulated active carbon layer of step 3; Its carbon leaching material is owing to have special pore texture; Formed the minute aperture of different shape, thereby constituted huge adsorption surface area, can effectively remove deliquescent small organic molecule, colourity, chlorine residue etc. in the water with size.

8. the described rete of step 3, it is last one deck filtering material, utilizes its microvoid structure, can effectively remove impurity such as colloid in the sewage, small organic molecule, bacterium, virus.

The invention discloses a kind of domestic sewage treatment unit; Studied the feasibility of the sewage regeneration techniques being introduced average family; Developed a cover and be applicable to the sewage reuse device that family uses, to technology of middle water recycle popularize and water saving subtracts dirty significant.

Embodiment:

In conjunction with Fig. 1 and Fig. 2, the present invention is further described through embodiment.

Embodiment 1

Domestic sewage treatment unit of the present invention is characterized in that comprising by water purification catridge 2 and actuating unit two portions constituting; Water purification catridge 2 is arranged at tank 1 water outlet bottom, connect water pipe again after, connect actuating unit.

Described actuating unit mainly is made up of middle water hopper 8, vacuum breaker 6, rising pipe 7, piston 3, piston rod 4, pin handle, spring 5, vacuum breaker 6; Wherein, water hopper 8 during the water pipe of family expenses connects, the water outlet of hopper 8 is through the rising pipe 7 vacuum breaker 6 back dischargings of flowing through; Vacuum breaker 6 is by piston 3 trip switchs, and piston 3 is connected with spring 5 through piston rod 4; It is consistent that the open-circuit position of vacuum breaker 6 and piston 3 move down direction.

Domestic sewage flows into water purification catridge 2 through tank 1, and sewage successively passes filter core under action of pressure, and the water after the processing is discharged from the water pipe of family expenses, and water hopper 8 is for use in the entering.7 places are equipped with vacuum breaker 6 at rising pipe, and water can only be discharged from inside to outside, have prevented to form the backflow of clear water in the negative pressure process.After treating that sewage drains, unclamp foot-operated, spring 5 resiliences, piston 3 moves up through piston rod 4, returns back to original state.

Embodiment 2

The water purification catridge of this device designs according to the MULTIPLE COMPOSITE work principle of filter; It is 5 layers that filter core is divided into from top to bottom; Every layer filtration medium is all selected to the removal of certain pollutent; Be respectively: coarse filtration layer 9, filter bed of essence 10, layer of fibers 11, granulated active carbon layer 12 and rete 13, the structure of water purification catridge and filtering layer are arranged as shown in Figure 2.

Because what the water purification catridge of this device adopted is the mode of independent filling, complete installation; So the difference that can require according to the difference and the effluent quality of raw water quality is selected different filter media for use; Filter the number of plies and also can suitably increase and decrease, apply in a flexible way according to practical situation.

The process characteristic of this device:

(1) open up second water source for urban water supply, can reduce the consumption of " go up water " (tap water) significantly, conserve water resource greatly, thus strengthened water resources to society, economic, ecological guaranteeing role;

(2) solved " following water " (sewage) to a certain extent to the contaminated water source problem, thereby played the effect at protection water source, had very big social benefit and economic benefit;

(3) this device is that unit uses with the family, need not lay pipe network, need not concentrate water delivery, need not take up an area of and found the factory, and has solved extensive intermediate water reuse system and has built difficult problem;

(4) utilize idea to promote into average family again technology of middle water recycle and water resources, improve the consciousness of saving water of the whole society, help constructing " saving type " and " harmonious co-existence between man and nature " society.
