Description

Plain type filter-cloth filtering device

Technical field

This utility model relates to sewage treatment area on a small scale, particularly relates to a kind of plain type filter-cloth filtering device.

Background technology

In recent years, along with the raising of environmental requirement, some small-scale sewage disposal to reach " urban wastewater treatment firm pollution Thing discharge standard " GB18918-2002 one-level A standard, the SS advanced treating to be carried out to effluent quality, the most commonly used It it is filtering technique.

In filtration art, although traditional sand filtration technology technique is simple, filter material easily takes, but the regeneration washing of sand filter is numerous Miscellaneous, the less stable of filtration, and civil engineering floor space is big, structure is complicated, these problems promote insider constantly to seek and Advance the filtering technique that new filtering technique development is new.

Filtering cloth filtering pool is a kind of brand-new filtering technique, good filtration effect.But filtering cloth filtering pool there is also, and cost is high, safeguard pipe The problem that reason is complicated, is not well suited for the small-scale sewage disposal of below 100T/D.

Utility model content

For the problem of current advanced treatment of wastewater, the purpose of this utility model is to provide a kind of at small-scale sewage The plain type filter-cloth filtering device of reason factory, invests little, simple to operate；Solve conventional filtering techniques cost height, maintenance management complexity Problem, sewage after treatment can reach " urban wastewater treatment firm pollutant emission standard " GB18918-2002 one-level A row Put standard.

For achieving the above object, this utility model takes techniques below scheme:

A kind of plain type filter-cloth filtering device, when the process technique gone out in entering outside using, i.e. system are run, sewage is through filter disc Module ecto-entad percolation filters；Filter disc module is spigot-and-socket, uses and seals at special (purpose) rubber pad docking port, can Fast Installation and Splitting out, the surface of each filter disc is covered with the long wool filter cloth of 10 μm filtering accuracies, forms the filtering layer of densification, it is possible to retain during filtration Particulate matter in suspension, solves the problems such as tradition filtering cloth filtering pool structure is complicated, install trouble, maintenance cost is high.

Described plain type filter-cloth filtering device, main body uses the body structure that corrosion resistant plate is welded, and is divided into filtration single Unit, water collecting unit and water unit three part.

Described filter element is positioned at whole device top, has water inlet top on the side, and water inlet has intake chamber anti-slow Rush in water to wash away, be evenly arranged in filter element and filter disc module is installed.

Described filter disc designs for blocking criteria, square structure body, and each filter disc is a standard module, and each module has Two outlets, filter assemblies predominantly stretches tight on stainless steel structure body and wraps up in the filter disc module of long wool filter cloth, and filter disc module is vertical Inserting the socket joint hole of the space bar of filter element and water collecting unit, before filter, liquid enters in filter disc module through filter cloth, after filter liquid from Filter disc module outlet flows into water collecting unit.

Described water collecting unit is positioned at bottom of device, water from filter disc module outlet flow into, have gripper shoe the most uniform for Supporting the dividing plate between filter element and water collecting unit, every piece of gripper shoe has bottom to have the mouth of a river；Water flows through water collecting unit side Face is crossed the mouth of a river and is flowed into water unit；Evacuated tube is installed for emptying bottom water collecting unit.

Described water unit is positioned at device side, and water (flow) direction is bottom in and top out, and outlet, outlet and device are arranged at top Water inlet has the horizontal drop of 10cm, and after filter, liquid is discharged by outlet.

The beneficial effects of the utility model:

This utility model general solution problems the such as certainly investment of tradition filtering cloth filtering pool is high, structure is complicated, maintenance cost is high, are especially suitable for The small-scale advanced treatment of wastewater of below 100T/D.

Described device uses filter disc block combiner to form, and device integral device can overall ship；And filter disc modular filtration Device is easily installed cleaning than filtering cloth filtering pool, joint connection in site pipe fitting and after having connected, and can come into operation；And filtering cloth filtering pool Then generally require the installation carrying out filter cloth and vacuum pumping device, long construction period, trouble is installed.
