Description

A kind of Full automatic integrated water purifier back-flushing method

Technical field

The present invention relates to a kind of Water-quality treater sewage water treatment method, and in particular to a kind of Full automatic integrated water purifier back-flushing method, belong to environment-friendly products technical field.

Background technology

Continuous progressive and scientific and technical with society continues to develop, and people become more concerned with the earth that we depend on for existence, and most countries have also been fully recognized that importance of the environment to our human developments in the world.Each state is all taking active and effective measure improvement environment, reduces pollution；Mostly important among these is also that problem the most urgent is exactly water resources problems, fundamentally to solve water resources problems, except finding new water resource, waste water is carried out purified treatment be it is crucial be also important measures most directly effective at present；Purification of water quality is exactly the consumption for being reduced as far as water resource.With continuing to develop for society, the living standard of people also constantly improving, the consumption of water resource also being continuously increased, to the purified treatment of water resource into the most important thing；Present China each department water pollution is very much serious, and rivers, lake etc. need treatment containing more suspension；It is existing for processing rivers, the suspended solid pollutant in lake commonly use purifier, but the purifier for using at present needs substantial amounts of Valve controlling, easily breaks down, and the service life of equipment is shorter.Therefore, in order to solve problem above, it would be highly desirable to research and develop a kind of new Full automatic integrated water purifier back-flushing method.

The content of the invention

（One）The technical problem to be solved

To solve the above problems, the present invention proposes a kind of Full automatic integrated water purifier back-flushing method, and using siphon and the principle of backsiphonage, all Inlet and outlet waters, backwash turnover, without Valve controlling, service life is more long；The high efficiency filter of water cleaning systems, and energy automatic backflushing are ensure that, without separately setting the electric equipments such as backwash pump or air compressor machine, a large amount of capital expenditures and day-to-day operation, maintenance, upkeep cost can be saved.

（Two）Technical scheme

Full automatic integrated water purifier back-flushing method of the invention, comprises the following steps：

The first step：As that is filtered in filter chamber is constantly carried out, filter material surface starts to accumulate suspension and solid particle of the particle more than particle diameter of filter medium, at the same time, gradually increased through the pressure needed for filtrate by the water distribution of U-tube, this pressure exceed from elevated tank downflow weir to filter material surface between water column formed pressure when, water inlet in elevated tank will no longer pass through filtrate, and the water level on filter material layer top can rise to siphon pipe tedge；

Second step：Water level constantly rises in siphon tedge, when the mouth of pipe of water level to auxiliary siphon tube, water falls into auxiliary siphon tube mouthful, portion of air is taken away by current, vacuum increase in auxiliary tube, exhaust tube in communication takes the air in siphon down-comer away, increase siphon pipe vacuum, liquid level in siphon down-comer constantly rises, the air in siphon pipe is further extruded, air is all drained by exhaust tube, finally, siphon tedge is contacted with the water surface in siphon down-comer, forms serial siphon effect；

3rd step：With the carrying out of siphonage, the pressure drop on filtrate top in filter chamber, in the case where bottom clear water zone pressure is constant, clear water in the clear water zone of bottom begins to pass filter plate and enters filter material layer, filtrate is backwashed, at the same time, the clear water in filtered water tank passes through communicating pipe to enter bottom clear water zone, the waste water for producing is backwashed by after siphon tedge, backwash trench being entered into siphon down-comer.

（Three）Beneficial effect

Compared with prior art, Full automatic integrated water purifier back-flushing method of the invention, Collecting flocculation, the technique such as precipitates, recoils, catchmenting, filtering in one, is operated without professional and can reach monomer fully automatic operation；Using siphon and the principle of backsiphonage, all Inlet and outlet waters, backwash turnover, without Valve controlling, service life is more long；The high efficiency filter of water cleaning systems, and energy automatic backflushing are ensure that, without separately setting the electric equipments such as backwash pump or air compressor machine, a large amount of capital expenditures and day-to-day operation, maintenance, upkeep cost can be saved.

Specific embodiment

A kind of Full automatic integrated water purifier back-flushing method, comprises the following steps：

The first step：As that is filtered in filter chamber is constantly carried out, filter material surface starts to accumulate suspension and solid particle of the particle more than particle diameter of filter medium, at the same time, gradually increased through the pressure needed for filtrate by the water distribution of U-tube, this pressure exceed from elevated tank downflow weir to filter material surface between water column formed pressure when, water inlet in elevated tank will no longer pass through filtrate, and the water level on filter material layer top can rise to siphon pipe tedge；

Second step：Water level constantly rises in siphon tedge, when the mouth of pipe of water level to auxiliary siphon tube, water falls into auxiliary siphon tube mouthful, portion of air is taken away by current, vacuum increase in auxiliary tube, exhaust tube in communication takes the air in siphon down-comer away, increase siphon pipe vacuum, liquid level in siphon down-comer constantly rises, the air in siphon pipe is further extruded, air is all drained by exhaust tube, finally, siphon tedge is contacted with the water surface in siphon down-comer, forms serial siphon effect；

3rd step：With the carrying out of siphonage, the pressure drop on filtrate top in filter chamber, in the case where bottom clear water zone pressure is constant, clear water in the clear water zone of bottom begins to pass filter plate and enters filter material layer, filtrate is backwashed, at the same time, the clear water in filtered water tank passes through communicating pipe to enter bottom clear water zone, the waste water for producing is backwashed by after siphon tedge, backwash trench being entered into siphon down-comer.

Embodiment described above is only that the preferred embodiment of the present invention is described, and not the spirit and scope of the present invention are defined.On the premise of design concept of the present invention is not departed from; the all variations and modifications that this area ordinary person makes to technical scheme; protection scope of the present invention all should be dropped into, claimed technology contents of the invention have all been recorded in detail in the claims.
