Description

Integral water purifier

Technical field

The utility model relates to integral water purifier, and particularly a kind of city occupies the integral water purifier of reuse after the advanced treatment of villager's Drinking Water, industrial and mining enterprises' water water quality and part trade effluent and sanitary sewage.

Background technology

Along with the continuous development of modern production, resource is more and more nervous, and the water resources world is faced with the reality of sternly completing equally, and China south is the water quality lack of water, and the north is water yield lack of water, and available water resources is on a declining curve.Human society constantly develops, the also corresponding raising of people's demand.The production demand that people are different has different requirements to water quality.Existing first-generation water purifier (FXZ), s-generation water purifier (TLZ), the initial stage is satisfied enterprise demand fully, because enterprise development needs the corresponding raising of water quality and quantity standard, original water purifier can not satisfy related request.It is the full-automatic water quality refining plant of one that the water purifier assemblage closes purification process such as reaction, precipitation, filtration.Water quality is lower but existing product has the water of producing, the high shortcoming of the little while blowdown flow rate of water production rate, incompatible more and more higher national water purification parameter request.For example the coacervation thing is a viscous substance in the water body, directly contacts with the quartz sand filter media layer, and the quartz sand surface layer easily hardens, unfavorable backwash and many water loss.

The utility model content

Goal of the invention: utility model technical problem to be solved is at the deficiencies in the prior art, and a kind of integral water purifier is provided.

Technical scheme: the utility model provides a kind of integral water purifier, comprise housing, stretch into housing water inlet pipe, shore pipe and backflushing water intake pipe, be arranged on intravital first reaction chamber of shell, first packing layer and filter material layer, below first reaction chamber, be provided with the negative area; Also be provided with second reaction chamber that the bottom communicates with water inlet pipe and shore pipe and extends into the negative area in described first reaction chamber, be arranged at intervals with grid in first reaction chamber and in second reaction chamber; Below first packing layer, also have additional second packing layer; First packing layer and the second packing layer angle are oblique staggered arrangement; Above filter material layer, be provided with anthracite coal measure.

In the utility model, there are two reaction zones to constitute reaction chamber, under the situation that volume does not increase, guarantee long reaction time.The coacervation thing is attached to above the hard coal when filtering in the water body, is convenient to backwash.Multi-layer net is to increase the water body flocs unit in equipment internal reaction space, slow down mixed water body water inlet speed, make mixed water body thorough mixing more in grid reaction, increase flocs unit collision probability, reaction thoroughly, reduce the suspended substance in the water body, thereby the effect of increasing water quality realizes that really water purifier obtains optimum water quality and quantity in limited space.

In the utility model, preferably, described water inlet pipe tangential direction shape in the shape of a spiral is communicated with the bottom of second reaction chamber.Guarantee to form sheet flocs unit current, do not react the dead band, make the water body mixture in equipment, can obtain filling a part reaction.

As further improvement of the utility model, also be provided with one and help wash pipe to be communicated with the bottom of first reaction chamber and second reaction chamber.Help the effect of washing pipe to be, during intermittent operation, the bottom mud of get excited earlier first reaction chamber, circular cone negative area.Purpose is to prevent that first reaction chamber, bottom, circular cone negative area mud from hardening; Also make reaction zone the utmost point in the short period of time throw out reach certain sludge concentration.

In the utility model, preferably, described second packing layer is by the inclined tube of aperture 50mm and be configured to.In the stability of guaranteeing current simultaneously,, increase desilting area, can improve water treatment capacity according to shallow pond sedimentation theory.Identical water inlet flow velocity can improve effluent quality.Guarantee that the prerequisite of effluent quality can improve the water production rate of single device simultaneously.Stay suitable water distribution layer in the middle of two layers of packing layer, constituting the settling section characteristics by first packing layer, second packing layer and water distribution layer is clearance height, and the residence time is short, and floor space is little.

As further improvement of the utility model, described filter material layer is a homogeneous quartz sand.

As further improvement of the utility model, described backflushing water intake pipe stretches into the intravital part of shell and radially is provided with a pair of above range pipe.Change former big resistance water distribution into the slight drag water distribution, backflushing water intake pipe, range pipe also have the function of the water header and the arm that catchments simultaneously.

As further improvement of the utility model, perforate and twine stainless (steel) wire outside the hole on described range pipe makes evenly water distribution rationally, and homogeneous filtering material is difficult for stray arrow.

Beneficial effect: treating plant described in the utility model adopts integral structure, the water inlet energy consumption is less, save washing water quantity, the remarkable filtering layer flushing of coagulation clarification and filtration purifying water effect is clean fast, before great advantage is to reach and transforms 1.5 times of the water production rate of equipment of the same type, save water resources, and reduced energy consumption.
