Description

The second-stage treatment device that in underground water, ferrimanganic exceeds standard

Technical field

The utility model relates to Water warfare field, the second-stage treatment device that particularly in a kind of underground water, ferrimanganic exceeds standard.

Background technology

In recent years, government has carried out a large amount of " red beds well-digging " people's livelihood engineerings in water-deficient area, vast western countryside, many lack of water peasant households are made to have had motor-pumped well, and submersible pump has been installed, use " tap water ", but there is content of iron and manganese in a big chunk red beds underground water higher, considerably beyond safe standard for drinking.

Make a general survey of technical field of water purification, for solving underground water ferrimanganic excessive problem, multiple efficient water technology and device are developed at home at present, but in groundwater treatment engineering, often need to use biological uniform filtration device or add deferrization and demanganization bacterium liquid etc., all there is use cost higher, the problems such as complicated operation and water treatment effect instability; And the Poor Farmers Household being mostly to disperse lived in vast Based on Red Bed, buy complete water processing establishment expensive, both uneconomical also unrealistic, therefore, in daily life when using underground water, namely people often only by using after simple precipitation, filtration, and in water, iron, manganese element and other foreign matter contents are higher, long-term drinking health risk.

Utility model content

The utility model aims to provide a kind of with low cost, workable, easy to maintenance, and the second-stage treatment device that the significant underground water ferrimanganic of decontamination effect improving exceeds standard.

For this reason, the technical scheme that the utility model adopts is: the second-stage treatment device that in a kind of underground water, ferrimanganic exceeds standard, comprise shower nozzle aerator, expose to the sun oxygen pond, filter vat and settling tank, described shower nozzle aerator is positioned at directly over oxygen pond of exposing to the sun, described filter vat comprises the first filter vat and the second filter vat, be equipped with sand grid, support gravel and quartz sand in described first filter vat successively, in the second filter vat, be equipped with sand grid, support gravel and manganese sand successively; Former water sprays through shower nozzle aerator oxygen pond of exposing to the sun, and carries out catalytic oxidation with abundant aeration, then carries out filtering, adsorbing through the first filter vat and the second filter vat successively, finally flows into settling tank and carries out precipitating rear for living; Have mudhole bottom described settling tank, the sidewall of settling tank is provided with rising pipe.

Further, described oxygen pond of exposing to the sun is arranged at left side, first filter vat, the second filter vat and settling tank are arranged at right side and interval setting successively from top to bottom, in addition, exposing to the sun the bottom in oxygen pond must not lower than the top of the first filter vat, and oxygen pond of exposing to the sun, the first filter vat, the second filter vat, settling tank are successively by pipeline connection, this arranges compact construction, rationally, can be farthest cost-saving.

Further, the cone apex angle of described shower nozzle aerator 60 °, basal diameter 0.1m, eye diameter 4mm, percentage of open area 15%, eyelet flow velocity is 2.5m/s, mounting height distance is exposed to the sun oxygen pond top 0.6m, the parameters combination of this shower nozzle aerator can make that former water is more large-area to be contacted with oxygen, and the aeration better effects if played, promotes subsequent filter and absorption.

On the basis of such scheme, the laying depth of described quartz sand, manganese sand and support gravel is 0.2m, and the grain size of gravel of support gravel is 8 ~ 16mm, described quartz sand, manganese sand and gravel laying order are first path grain, rear particle size grain, the filtering layer be laid to thus can better filter and adsorption effect, and manganese, ferro element and other impurity in the former water of the more effective reduction of energy, provide the domestic water of more high-quality.

The beneficial effects of the utility model are: structure is simple, lower cost for material, workable, safeguard convenient, decontamination effect improving is remarkable, and in use, do not need to add biological or chemical degerming agent, the secondary pollution of water quality is avoided while reducing costs, guarantee the safety of urban residents' domestic water of vast scattered settlement, also effectively solve Based on Red Bed puzzlement underground water ferromanganese excessive problem for many years.
