A reaction cylinder is provided at the center of the housing, three stages of horn-shaped drop-aeration discs are sequentially provided from the top of the reaction cylinder wall to the middle portion, each of which includes a large round opening facing upwards, and a smaller round opening sheathed onto the reaction cylinder wall, wherein the second stage drop-aeration disc has diameter of the larger round opening larger than that of the first stage drop-aeration disc, and the third stage drop-aeration disc has diameter of the larger round opening larger than that of the second stage drop-aeration disc. The utility model has advantages of reasonable structure, high efficiency, stable effect, saved investments, convenient management, capability of continuous water supply, wide adaptation range or the like. The device uses a jet flow aeration machine and a staged drop-aeration device for continuous aeration, so that the aeration time is prolonged, the contact area between the air and the water is increased, oxidation reaction of the iron and the manganese is reinforced, the divalent iron and the divalent manganese are absorbed on the filtering material of the filtering pool to form active filtering film. The active filtering film has function of catalysis, and can further remove iron and manganese in the water.
Description
Technical field
The utility model relates to aerating apparatus, especially relates to a kind of underground water gravity type ferrum and manganese removal continuous drop aeration.
Background technology
Trace iron and manganese are the elements of needed by human in the underground water, but iron manganese content surpasses state specified standards in the underground water, it will be drunk and process water brings very big harm to life: the underground water of the high ferrimanganic of long-term drinking can bring out the various pathologies of human body, jeopardizes health and life; In the industrial production, as papermaking, brewage, industries such as food-processing, control, printing and dyeing, silk, plastics, process hides, film, plating, boiler, if use the underground water of high ferrimanganic, can cause serious accident, jeopardize the normal operation of production.Therefore, must take treatment process, reduce ferrimanganic in the underground water source content that exceeds standard, make it meet the regulation of country's " drinking water sanitary standard ".Be iron (Fe)≤0.3mg/l, manganese (Mn)≤0.1mg/l.
The villages and small towns equipment of removing iron and manganese mainly adopts the steel construction pressure type to filter and two kinds of forms of gravity filter at present, these two kinds of equipment of removing iron and manganese, in utilization, also exist many technological deficiencies: the one, gravity filter equipment is the structure of dissolved oxygen in water body not, water body only passes through simple pipe-line transportation, behind the aeration, ferrous iron in the water body changes in the ferric process, not sufficient as yet agglomeration process just enters filter bed fast, make iron in filter bed, hypomere is adsorbed, form the irony bed, because iron has more the ability of adsorption and oxidation than manganese, in case just at all can not demanganization when therefore equipment is in this situation; The 2nd, the pipeline dissolved oxygen must pass through the certain reaction time, and this point do not consider in prior art equipment, thereby makes oxygen deficiency in the water, can't make filter bed finish the process of ferrimanganic in the oxidation removal water, so that the active filter film of removing ferrimanganic can't form.
Summary of the invention
The utility model mainly is to solve iron, manganese content height in the underground water, and existing installation deferrization and demanganization effect is not satisfactory, the dissolved oxygen in water deficiency, and active filter film such as can't form at technical problem on the filter bed.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: this underground water gravity type ferrum and manganese removal continuous drop aeration comprises housing, water inlet pipe, rising pipe, position near housing bottom in housing is provided with the filter beam, the filter beam is provided with the integral filter plate, this screen plate is provided with some filters, described housing center is provided with reaction tube, jet aerator is installed at the reacting cylinder body top, this jet aerator water pipe that taps into suitable for reading, end opening connects mixing battery, and mixing battery extends in the reaction tube, the top of described reaction barrel to middle part is provided with three grades of horn-like drop water aeration dishes successively, the big round mouth of each drop water aeration dish up, on the then sheathed reaction barrel of its little round mouth, wherein secondary drop water aeration dish is bigger than the big round mouth external diameter of one-level drop water aeration dish, and three grades of drop water aeration dishes are bigger than the big round mouth external diameter of secondary drop water aeration dish.
In technique scheme, after first step drop water aeration dish filled with water, overflow automatically to second stage drop water aeration dish, after the second stage drop device filled with water, automatically overflow to third stage drop water aeration dish, after the third stage drop water aeration dish filled with water, overflow on the filter material layer of integral filter plate automatically.
The utlity model has rational in infrastructure, efficient height, effect stability, reduced investment, convenient management, but continuous water supply, advantage such as applied widely.It is by jet aerator and ladder of cascades aerating apparatus continuous aeration, prolonged aeration time, increase gas and water contact gear ratio area, the oxidizing reaction of ferrimanganic is strengthened, after using this device, oxygen in water reaches the 80-90% of saturation value, impels divalence Fe, divalence Mn to be adsorbed on the filtrate of filter tank and forms active filter film, this active filter film has katalysis, can further remove iron and manganese in the water.
In addition, the utility model device need not to add separately any medicament when removing ferrimanganic, just can be with CO in the water
2Gas and volatile matter are discharged in the air, and compare with the single stage system processing, and the utility model deferrization and demanganization must not improve former water ph value, does not need the water after handling is carried out acidifying.Therefore greatly reduce cost of water treatment.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
