Abstract

The utility model discloses a water treatment device integrating the adsorption, the sedimentation and the separation, which comprises a slop pail, a precoat barrel, a pump and a sedimentation and separation filter in which a septum drum is provided to divide the filter into an exterior sedimentation chamber and an interior filtration chamber in which a filtration element is provided. The equipment running, the high concentration suspension goes forward spirally in the sedimentation chamber to subside most particle suspended substance, and the supernatants enter the filtration chamber to participate in filtration. The introduction of the sedimentation chamber widens the application range of diatomite technology, so that the filtration of the wastewater with high concentration suspended matter is possible; and compared with the adsorption and separation integration technology, the utility model can effectively delay the raise of filtration water head and prolong the operating time. The utility model has the advantages of simple and close structure and high efficiency of water treatment.

Absorption, sedimentation, separation integrated water treatment device
Technical field
The utility model relates to a kind of absorption, sedimentation, separation integrated water treatment device, belongs to environmental technology and water treatment field.
Background technology
Nowadays the diatomite filtration technology is widely used, especially diatomite filtration has caused concern widely especially with the combination of various technology, but the diatomite filtration technology is applied to in the water treatment more, the process object turbidity is low, water quality is better relatively, and this has just influenced the application of diatomite filtration technology in sewage and it is with absorption, the combination of coagulating, because can make in absorption or the coagulating process that concentration of suspension increases in the water, especially with absorption reaction for very.Adding of heavy dose of sorbent material makes that filtering cloth head rose rapidly when diatomite separated, and makes to make system operation time short by the filtering terminal point of the very fast arrival in diatomite filtration unit.
Summary of the invention
The purpose of this utility model provides a kind of absorption, sedimentation, separation integrated water treatment device, to realize the high efficiency separation processing to high suspended matter concentration sewage.
Absorption of the present utility model, sedimentation, separation integrated water treatment device comprise the slop pail of being with stirrer, precoating bucket, pump and the settlement separate strainer of band stirrer; Be provided with in the settlement separate strainer with settlement separator be separated into outside settling pocket and self-filtering chamber every tube, the center of self-filtering chamber is equipped with filter element, the top of settlement separate strainer is equipped with tensimeter and rising pipe, rising pipe is communicated with the precoating bucket through first valve, the water-in of pump also is connected to two water inlet pipes, article one, water inlet pipe links to each other through the outlet of the 3rd valve with the precoating bucket, and another water inlet pipe links to each other with the water outlet of slop pail through the 4th valve; The water outlet of pump also is connected to three rising pipes, article one, the outside settling pocket bottom of rising pipe in the 5th valve and settlement separate strainer links to each other, the self-filtering chamber bottom of second rising pipe in the 6th valve and settlement separate strainer links to each other, article three, rising pipe is divided into two-way through the 7th valve, wherein one the tunnel links to each other with the filter element water outlet, another road second valve links to each other with the under meter import, and the outlet of under meter is connected with water shoot, and the slop pail bottom links to each other with rising pipe through the 8th valve.
The device working condition:
Adopt diatomite as precoating paint, forming thick on filter element is the filtering layer of 1-5 millimeter, in slop pail with the online sorbent material that adds of amount of inlet water, stir formation suspension by stirrer, open the 4th valve, the 5th valve, squeeze into suspension in the outside settling pocket of fractionation by adsorption filtration chamber with pump, in the externally settling pocket internal screw rising of water inlet suspension liquid, the rising filtering velocity satisfies≤0.2mm/s, the sorbent material that the suspension of high density externally forms high density in the settling pocket band that suspends, in this effect that forms similar settling pond, the suspended substance that dams and rise, the supernatant liquor overflow enters the self-filtering chamber and participates in filtering, treated water effluxes through behind the under meter, show that when filtering the pressure value of reaching capacity solid-liquid separation finishes, stop filtration, close the 4th valve, the 5th valve.Open the 3rd valve, the 6th valve, oppositely water inlet is washed, and the high density adsorbent suspension of outside settling pocket is discharged by its bottom pipe.After finishing, back flushing begins the adsorption and sedimentation isolation integral cycle of a new round.
The beneficial effects of the utility model are:
The object that diatomite filtration is used often is a low-cloudy water, filtering cloth head rises fast in the adsorption separation technology operational process, the cycle of operation is short, is provided with every bucket in device, and the filtration chamber has been separated into outside settling pocket and self-filtering chamber, the introducing of settling pocket, enlarged the range of application of diatomite technology, make high suspended matter concentration waste water be filtered into for may, compare the fractionation by adsorption integrated technique, can effectively delay the rising of filtering cloth head, prolong working time.Absorption of the present utility model, sedimentation, separation integrated water treatment device, compact construction is simple, the processing efficiency height has solved fractionation by adsorption integration apparatus transient problems working time effectively, and the scope of application of diatomite filtration has been expanded to high turbid sewage by original low turbidity water.
