Description

Device for F content reducing treatment of drinking water

The utility model belongs to water treating equipment, and what particularly relate to a kind of tap water falls the fluorine treatment unit.

Fluorine is an indispensable element in the human body, and is to take in the body through drinking of water mostly.But fluorine content is too high or too low in the tap water, all will cause the generation of disease and is unfavorable for HUMAN HEALTH.For this reason, need be drinkable for the too high water of fluorine content through falling fluorine processing rear.In view of above-mentioned known reason, at present, occurred and formed activated alumina absorption method, the fluorine-reduction processing method and the corresponding apparatus of various ways such as electroosmose process, coagulant sedimentation, bone carbon method, ion exchange method.Because tap water fluorine-reduction processing method and device still are in constantly among the perfect exploratory development, so, there are following defective and deficiency in the prior art; 1. aluminium composition surpasses standard for drinking in falling the water after the fluorine device is handled, as the method for application of active alumina adsorption.2. handle the useful ion content that human body needs in the water of back and reduce, as Fe ⁺⁺Useful ionic minimizing such as ion is unfavorable for HUMAN HEALTH equally.3. it is too high to handle the back water turbidity.4. treatment unit complex structure, volume are big, operation labour intensity is big, running cost is taken higher.

The purpose of this utility model provides that a kind of structural volume is little, stable performance and can realize that control automatically and effluent quality meet standard for drinking the fluorine treatment unit falls.

For achieving the above object, the technical scheme that the utility model adopted designs this device according to the electrocoagulation reducing fluoride method.

It is an electrolysis, hydrolysis, cohesion, absorption, precipitation, filtering cascade process that so-called electrocoagulation falls fluorine actual, that is to say the aluminium hydroxide flco that produces by the electrolytic aluminum plate electrode chromium complex with fluorion in the planar water and fluorine.Because the aluminium hydroxide flco that produces is to be formed by extremely purified aluminium electrolysis, and in entire reaction course, do not add other impurity, do not remove simultaneously in the water other to human body beneficial's trace element yet, so, can guarantee that flco is to the extremely strong adsorption activity of the chromium complex of fluorion and fluorine.Whole device is made up of a reaction box and a two-position controller.Its reaction box is made of casing, electrolyzer, flocculation groove, settling bath, filter vat, water-in, water outlet, mud discharging mouth etc.Promptly in the reaction casing, be provided with electrolyzer, flocculation groove, settling bath, four spaced-apart parts of filter vat by its vertical direction.Wherein, electrolyzer is built-in with and is no less than 36 aluminum electrode plate, and the peripheral ring of its notch end is put a distributing trough.The flocculation groove adjacent with electrolyzer is built-in with more than 4, and its internal structure is the tubular reactor of labyrinth-like, and water inlet is arranged at reactor top, and there is water outlet the lower end, and flocculating, trench bottom is porose to communicate with settling bath.Settling bath is built-in with 60 ° monoblock type inclined tube heap.The top of settling bath and filter vat partition is shaped on the hole and was used for water.The filtrate that filter vat is built-in with up-thin-low-thick (granularity) is in order to filter dirt impurity.The original water inlet pipe is connected to bottom of electrolytic tank, and pure water inlet is connected to filter vat bottom, and the effluent trough of suspend on the filtrate in the filter vat recoil washing trough and the outer setting of its filter vat joins, and the two all is used for washing and discharge the dirt impurity etc. of filtrate.Two-position controller is to be made of silicon controlled rectifier and switch circuit, mu balanced circuit, trip switch and rectifying circuit, controlled polarity reversing circuit and control polarity reversing circuit etc., make the direct current output element owing to adopt high-power silicon controlled rectifier, the Faradaic current of its output can be regulated voluntarily according to fluorine content height, can realize the automatic conversion of current polarity (promptly automatically the utmost point) because of control section adopts multichip integrated circuit.The controller output end positive and negative electrode is connected to the aluminum electrode plate in the electrolyzer, and the processing of whole device, use are undertaken by following flow process; Water of high fluorine content should be sneaked into an amount of diluted acid and the pH value of water is adjusted to about 6.5 before entering electrolyzer by original water inlet, this former water is from bottom to up by being provided required Faradaic current to battery lead plate by controller, electrolysis goes out aluminium hydroxide flco and the tubular reactor in distributing trough flows into the flocculation groove, when slowing down water flow process, strengthens the reactor of maze-type structure its reaction effect, the fluorine water that falls that is entered in the settling bath by flocculation bottom land perforate is precipitated in the uphill process in the inclined tube heap and the aluminium hydroxide flco that adsorbs fluorine is discharged from shore pipe, enters filter vat through the water of this post precipitation in the perforate of crossing Qi Bi top and filters by water outlet and flow out as clear as crystal qualified low fluorine water.

Reaction box in the utility model is owing to adopt that electrolyzer, flocculation groove, settling bath, filter vat are closed four is one structure design, has rationally distributed, compact construction, is convenient to the characteristics installed and used.This device is all processes that is fallen fluorine by electrocoagulation in the controller control reaction box, in view of controller adopts existing comparatively advanced circuit layout, have that dependable performance, working stability, volume are little, in light weight, the characteristics of operation simple and convenient, outstanding is can realize automatically the utmost point and unattended and this device applicable to various water of high fluorine content source the fluorine processing falls, and can obtain its fluorine content, PH, Al ⁺⁺, turbidity value all meets the water quality of the drinking water standard of country promulgation.
