Description

Water reuse treatment facility in the integrated form

Technical field

The utility model relates to a kind of sewage disposal device, especially a kind of middle water reuse treatment facility.

Background technology

At present, the conventional process of handling for middle water reuse has following several substantially: the one, and bio-contact oxidation+filter-sterilized technology; The 2nd, dosing air supporting (or dosing precipitation)+filtration+gac (or ultrafiltration) and sterilization process; The 3rd, film activity mud technology; The 4th, acidication+BAF+filtration and sterilization process.First kind of art breading effect stability is reliable, but the technical process complexity, the construction investment height, the treatment facility floor space is big, and major equipment can only carry out the in-situ processing manufacturing; Second kind of technology has that construction investment is few, and running starts characteristics such as flexible, but adaptive surface is narrow, and can only be used for bathing, washing is the processing of the cleaning water at water source, and effluent quality is relatively poor and unstable; The third art breading water quality is good, and treatment scheme is simple, but the construction costs height, work-ing life lacked (general 2-3) by the ultra-filtration membrane that is used for solid-liquid separation, and processing cost is higher; The 4th kind of technology investment is low, and floor space is little, but that BAF goes out water suspension is higher, could reuse after needing to filter, and this is the shortcoming of prior art

Summary of the invention

The purpose of this utility model provides a kind of novel middle water reuse treatment facility, and it has, and equipment manufacturing cost is low, floor space is little, the characteristics that treatment effect is good.

The purpose of this utility model is achieved through the following technical solutions, it comprises housing, housing is provided with inlet flume, the place is provided with the flap reaction tank at the corresponding inlet flume of housing internal upper part, the bottom is provided with inclined-plate clarifying basin in housing, the flap reaction tank links to each other with the swash plate reaction tank by effluent trough, it is characterized in that: the side at the swash plate reaction tank links to each other with the flotation reaction tank that swash plate reaction tank top is set by water outlet, the flotation reaction tank links to each other with heavy filtrate biological filter by pipeline, top in heavy filtrate biological filter is provided with the light filter material biological filter, and the side in the light filter material biological filter links to each other with clear water zone by water outlet.

The utility model is owing to adopt technique scheme, the upper and lower layout of settling tank and flotation cell, improved the height of this equipment, make the water outlet run by gravity enter follow-up biological filter and become possibility, greatly reduce processing cost, double-layer filter material is adopted in the biological filter simultaneously, and it has the following advantages: (1) double-layer filter material is thick down thin, prolong the backwashing time in filter tank greatly, reduced the energy consumption of system; (2) arrange C, N reaction tank in same pond, upper and lower two-layer filtrate is respectively C, N reaction tank; (3) the low particle diameter of upper strata filtrate has effectively been removed suspended substance in the water, has overcome existing aeration type biological filter and has gone out the water suspension height, and needing increases filtering basin, goes out water suspension ability shortcoming up to standard, and treatment scheme is simplified more; (4) less pond holds and floor space: the BOD in this filter tank ₅Volumetric loading is conventional activated sludge method or contact oxidation method 6-12 a times, so its pond holds and floor space has only about 1/10 of activated sludge process or contact oxidation method, has saved floor space and a large amount of civil engineering costs greatly; (5) simplify treatment scheme: because double-layer filter material C/N aeration type biological filter reactor is to the biological crown_interception of suspended substance, make in the water outlet active sludge seldom, so do not need to be provided with second pond and filtering basin, treatment scheme is simplified, and floor space is further reduced.
