Description
Technical field
The invention belongs to drinking water treatment equipment field, particularly a kind of integral water purifying device removed for ground water hardness.
Background technology
Much higher hard or too lowly all can affect our HUMAN HEALTH in water, also can make troubles to daily life simultaneously.Such as, when washing with hard water can and soap response produce infusible precipitate, except affecting washing effect, clothes fiber also can be made to harden become fragile fragile, can puckery when having a bath wash hair with hard water.In regulation tap water, total hardness content should lower than 450mg/L(in CaCO3 in existing " drinking water sanitary standard " (GB5749-2006)).
Calcium ions and magnesium ions at present in the hardness minimizing technology of drinking water treatment field comparative maturity is utilize the precipitator method to make a return journey to dewater, uses the medicament precipitated calcium magnesium ions such as calcium hydroxide, sodium hydroxide, sodium carbonate usually.But the problems such as the precipitator method exist precipitin reaction time length, reaction is carried out thoroughly, calcium ions and magnesium ions residual concentration height, the pH of product water also can be caused significantly to raise.In addition, because generated contents of precipitate is higher, cause filtering unit back flushing frequent, significantly increase the personal water water yield and production cost.How according to the problems referred to above, the fundamental characteristics of association reaction, designs and a kind ofly novelly will be conducive to the solution of ground water hardness problem except hardness equipment and device.
Summary of the invention
Goal of the invention: the object of the invention is according to the existing response characteristic except hardness medicament, provides that a kind of effluent quality is safe, simple to operate, working cost is low, take up an area the little integral water purifying device removed for ground water hardness.
Technical scheme: the invention provides a kind of integral water purifying device removed for ground water hardness, the cone-shaped body comprising inlet unit, adding of agent unit, main body and be inverted in main body, the summit of described cone-shaped body is connected with inlet unit, bottom surface opening; Described cone-shaped body is provided with initial reaction unit and microdilatancy coarse filtration unit from bottom to top successively, and described main body is provided with water distribution layer, depth type filtration unit, catchment area and disinfection unit from top to bottom successively; Described adding of agent unit is located in inlet unit.
As improvement, the cone angle of described cone-shaped body is 20-50 °.
Improve as another kind, the medicament that medicament addition device adds is sodium hydroxide, and dosage is 30-150mg/L.Do
For another kind improves, the hydraulic detention time in initial reaction unit is 0.1-0.5min.
Improve as another kind, fill the pottery sand of particle diameter at below 0.5mm in expansion coarse filtration unit, the thickness of expansion coarse filtration unit is 0.5-2.0m; Expansion coarse filtration unit turgidity is at 5-15%.
Improve as another kind, it is the quartz sand of 0.85-1.35 that described depth type filtration unit fills particle diameter, and the thickness of depth type filtration unit is 0.8-1.2m; The filtering velocity of depth type filtration unit is 8-12m/h.
Improve as another kind, arrange the short-handled filter head for catchmenting in described catchment area, the height of catchment area is 0.2-0.5m.
Improve as another kind, in disinfection unit, hydraulic detention time is 5-10min.
Beneficial effect: the integral water purifying device removed for ground water hardness provided by the invention according to traditional underground water except the reaction process of hardness medicament and characteristic design, have except advantages such as hardness process are rapid, simple to operate, working cost is low, effluent quality is good, there is the advantage that floor space is little simultaneously.
Device provided by the present invention is arranged according to the fundamental characteristics except hardness reaction that early stage, a large amount of institute drew and the requirement of subsequent cell to influent quality by the setting of initial reaction unit, significantly improve the process of reacting and carrying out, meet the demand of subsequent processing units to influent quality simultaneously, be conducive to the normal operation of subsequent disposal, and finally ensure effluent quality.
Specifically, the microdilatancy coarse filtration unit that the present invention is arranged has selected particle diameter less and pottery sand that is that cannot use in general filtration procedure (general ceramic grain filter particle diameter used is between 0.5-5mm), thus facilitates effective utilization of resource; More importantly, in the solution of the present invention, pottery sand has crucial effect.Because particle diameter own is less and proportion is less, microdilatancy or micro-suspension can be realized relatively easily under ascending current effect; Simultaneously owing to having comparatively concrete dynamic modulus, effectively catching, absorption hardness can remove the throw out that process generates, and throw out be constantly adsorbed in around self; By the faint collision between pottery sand and itself vibrates, the throw out of attachment and self component are combined, and in use constantly grows up, facilitate the increase of thickness of filter bed, do not need to carry out backwash process, avoid the problem needing regular back flushing in traditional Interception process.The microdilatancy coarse filtration unit that the present invention is arranged adopts inverted cone-shaped body reactor types, the pottery layer of sand degrees of expansion of different heights has certain difference, bottom expansion is higher, top expansion is less does not even expand, this and water (flow) direction match, thus can effective guarantee rejection effect, the process for subsequent cell provides good condition.
The present invention adopts sodium hydroxide as except hardness medicament, its comparatively faster speed of response and form the relatively less feature of throw out and determine subsequent technique and can normally run, be the medicament corresponding with subsequent technique form.And sodium hydroxide except hardness advantage of lower cost, thus be conducive to reducing running cost.
The depth type filtration unit that the present invention is arranged can guarantee that effluent quality meets the demands, and due to water inlet in particle content relatively low, thus there is the longer recoil cycle, generally can reach more than 5-7 days, be significantly higher than the 24-48h of general filtration procedure, significantly reduce the water consumption of back flushing process.
This device, after later stage steady running, is regularly removed the pottery sand being coated with a large amount of calcium carbonate, magnesium hydroxide and so on dirt settling, can be developed and utilized further, saving resource, and avoid secondary pollution problem from system.
The disinfection unit that the present invention is arranged also can double as the backwash water storage pool of depth type filtration unit, miniature clean water basin use, and saves space further.
