Abstract
The invention provides a mechanical filter for chromium wastewater treatment integrated equipment. The mechanical filter comprises a filter tank body, wherein the filter tank body is provided with a water inlet pipe, a water outlet pipe, a high-pressure air inlet pipe and an air outlet pipe; the interior of the filter tank body is divided into a coarse filtration layer at an upper layer and a fine filtration layer at a lower layer; the high-pressure air inlet pipe is provided with a high-pressure air pump and a pressure gauge; the air outlet pipe is provided with an electromagnetic valve, and the inlet of the air inlet pipe is provided with a water diversion baffle. The mechanical filter is simple in structure and reasonable in design; high-pressure gas is adopted to promote waste liquid filtration, so that the filtration rate is relatively high; furthermore, the water diversion baffle is arranged at the water inlet pipe, feed liquor is distributed and blocked, direct scouring performed on the coarse filtration layer by the waste liquid is reduced, opening and closing of the air outlet pipe are controlled by a pressure machine, and safety problems caused by overhigh internal pressure of the filter are effectively avoided; furthermore, after being absorbed by active carbon once, filtered water is quite clean, can be directly used for other processes or be used for cleaning, so that environmental pollution is avoided, the water source utilization rate is also improved, and wastes are avoided.
Description
Technical field
The present invention relates to chrome waste water is processed, particularly a kind of chrome waste water processes complexes mechanical filter.
Background technology
At present, chromate waste water is mainly derived from metal plating industry, the domestic smelting of the intermetallic composite coating such as steel making industry enterprise
20 1 30 ten thousand tons of chromium slags of annual about discharge in gold and chemical industry.Harmful components in chromium slag be mainly solubility sodium chromate,
The hexavalent chromiums such as acid-soluble calcium chromate.Due to these Cr VIs and its pollution spread and constitute to ecological environment of running off
Harm.Next to that the strong basicity harm of chromium slag.When chromium slag is in outdoor storing up, after long-term rain shower substantial amounts of Cr VI from
Son oozes, runs off, penetrating into earth's surface with rainwater is molten, thus polluted underground water, also pollutes rivers, lake, and then endangers farmland, Aquatic product
And health.
General chrome waste water processing equipment need to carry out to chrome waste water the step such as being acidified, break chromium, adjust and reduce and separate, after separating,
General enterprise directly discharges after waste liquid discharge or coarse filtration, not only environment is caused with pollution, also result in water source wave simultaneously
Take.
Content of the invention
For the problems referred to above, the present invention proposes a kind of chrome waste water and processes complexes mechanical filter.
For solving above technical problem, present invention provide the technical scheme that
A kind of chrome waste water processes complexes mechanical filter it is characterised in that including filter tank body, described filter canister
Body is provided with water inlet pipe, outlet pipe, high-pressure pipe and escape pipe, is divided into coarse filtration layer and the lower floor on upper strata in filter canister body
Smart filter layer, separated by dividing plate between described coarse filtration layer and smart filter layer, be provided with hollow cylindrical in coarse filtration layer
Quartz sand coarse strainer, be provided with quartz sand fine straining net, quartz sand coarse strainer and stone in hollow cylindrical in described essence filter layer
The inside UNICOM of sand fine straining net；
Described water inlet pipe, high-pressure pipe and escape pipe are respectively positioned on filter tank body top, and with coarse filtration layer UNICOM, height is pressed into
Trachea is provided with high-pressure pump and piezometer, and described escape pipe is provided with electromagnetic valve, and described outlet pipe is located under filter tank body
Portion, and with smart filter layer UNICOM；
The porch of described water inlet pipe is provided with point water baffle plate and strengthening connecting plate, and described point of water baffle plate is in arrange obliquely, its with
The inwall institute of filter tank body is angled, and described α is 30 ~ 45 ° for α, and a point water baffle plate is provided with a point liquid passage, described point of liquid passage
Quantity be 2, and be symmetrical arranged, the section of point liquid passage is in circular arc, described strengthening connecting plate and point water baffle plate, a filter
The inwall of tank body is fixedly connected；
Further, described water inlet pipe, high-pressure pipe, be equipped with valve on outlet pipe；
Further, described piezometer is connected with electromagnetic valve.
The invention has the benefit that
A kind of chrome waste water proposed by the present invention processes complexes mechanical filter, including filter tank body, filter tank body
It is provided with water inlet pipe, outlet pipe, high-pressure pipe and escape pipe, in filter canister body, be divided into the coarse filtration layer on upper strata and lower floor
Smart filter layer, high-pressure pipe is provided with high-pressure pump and piezometer, and escape pipe is provided with electromagnetic valve, and the porch of water inlet pipe sets
There is a point water baffle plate, present configuration is simple, reasonable in design, promote waste liquid to filter using gases at high pressure, filtering rate is more quick,
Setting point water baffle plate at water inlet pipe simultaneously, feed liquor carries out point liquid and stops, reduces waste liquid directly washing away to coarse filtration layer, gives vent to anger
By forcing press control, it is excessive to be prevented effectively from filter internal pressure for the opening and closing of pipe, leads to safety problem, and the water after filtering,
Again after an activated carbon adsorption, very clean, directly can use for other operations, or be used for cleaning, it is to avoid to ring
The pollution in border, also improves water utilization rate, it is to avoid waste.
