Abstract
The utility model discloses a biological contact oxidation tower. The biological contact oxidation tower comprises a shell, wherein a water inlet is formed on the upper part of the shell, and a water outlet is formed on the lower part of the shell; the interior of the shell is divided into three sections, namely a water distribution section, a biological filling material section and a gas distribution section from top to bottom; and a mud discharging port is formed at the bottom of the shell. A gas collecting device is arranged on the top of the shell, and a filter screen is arranged in the gas collecting device. By adoption of the biological contact oxidation tower, water and mud residues at the bottom are collected in a concentrated mode, and then are concentrated, and the yielding water is returned to the water inlet and is subjected to circular treatment in a contact tower. The amount of return water can be controlled through a valve, so that the stable operation of the biological contact oxidation tower is further ensured. The chemical oxygen demand (COD), the oil content and the mud residues of the yielding water can be further reduced through the circular treatment, so that the quality of the yielding water is improved, and the investment cost and the treatment load of the follow-up processes are reduced at the same time.
Description
Technical field
The utility model relates to a kind of sewage treatment equipment, specifically is a kind of oil and organic biological contact oxidation tower equipment that reduces in the waste water.
Background technology
At present, to the processing of emulsifying liquid waste water, " air supporting+biochemistry " technology is the main flow that cold rolling emulsifying wastewater is handled.But the actual effluent index of investigating domestic a plurality of cold rolling mill emulsifying wastewater treatment systems is seen, accomplishes that really the enterprise of COD stably reaching standard discharging is also few.
Sum up the water quality situation and the discharge characteristics of this type of waste water, be not difficult to find that emulsifying liquid waste water has characteristics such as Pollutant levels height, wastewater flow rate are little, intermittently discharged.This has directly caused follow-up biochemical reaction to be difficult to the operation of continuous and effective, has influenced the stability of water outlet.And that scum silica frost is handled in air supporting is many, enter be easy to float over behind the sludge thickener above.Can not sink if untimely processing meeting is cumulative.Top scum silica frost is easy to kill caking through exposing to the weather.Wastewater effluent COD after the processing also is difficult to reach international and domestic first discharge standard.
Summary of the invention
The utility model equipment wants the technical solution problem to provide a kind of biological contact oxidation tower, through sufficient bio-contact oxidation, adopts aeration, biochemistry, coprecipitation mode to substitute the oil removal by air bubbling device, has solved the problem that scum silica frost produces.
The described a kind of biological contact oxidation tower of the utility model comprises shell, is provided with water-in in shell upper; The bottom is provided with water outlet; Be divided into three parts in the shell from high to low, be respectively water distribution section, biologic packing material section and gas distribution section, be provided with mud discharging mouth at outer casing bottom.
Improvement as the utility model is provided with gas extractor in cover top portion, is provided with filter screen in the gas extractor.
The mud discharging mouth of the utility model is positioned at the bottom, and the deposition body refuse in the waste water gets into settling system through shore pipe and further precipitates, and subsequent disposal mud is minimized, and guarantees the continuity and the stability of subsequent disposal system.
The water distribution section on top guarantees that microbiological treatment can not stop, and has improved the bio-contact oxidation time of waste water, has reduced the load of later stage biochemical reaction.
The gas extractor at top is collected gas delivery and is used the gas point to other, has practiced thrift the energy.The filter screen that natural gas gathering system has can also be removed a small amount of bubble that top produces.
During the operation of this biological contact oxidation tower, bottom water and body refuse are discharged further deposition, concentration through mud discharging mouth, and the water outlet centralized collection is returned once more to the biological contact oxidation tower internal recycle with pump and to be handled.Owing to can further guarantee the steady running of bio-contact oxidation through the size of the valve control backflow water yield.Circular treatment improves effluent quality with abundant reduction water outlet COD, oleaginousness and body refuse like this.
This equipment has solved the processing efficiency and the scum silica frost of such waste water completely and has handled problems, and makes the qualified discharging of final draining water quality, has satisfied production and environmental requirement.Also to have running cost low for this equipment simultaneously, and floor space is little, save energy, advantages such as operation use capable of circulation.
Description of drawings
Fig. 1 is the structural representation of this utility model equipment.
Embodiment
Like Fig. 1, the biological contact oxidation tower of the utility model comprises shell 1; Be provided with water-in 2 on shell 1 top; The bottom is provided with water outlet 3, it is characterized in that, is divided into three parts in the shell from high to low; Be respectively water distribution section 6, biologic packing material section 7 and gas distribution section 8, be provided with mud discharging mouth 4 in shell 1 bottom.Be provided with gas extractor 5 at shell 1 top, be provided with filter screen in the gas extractor 5.
The working process of the utility model is:
Waste water gets into water distribution section 6 water distribution uniformities in the biological contact oxidation towers through water-in 2, again with oxidizing tower in biologic packing material in the biologic packing material section 7 fully contact, guarantee the competent bio-contact oxidation time, guarantee the steady running of microbial reaction.
Inlet mouth 9 connects Aeration fan, and through 8 pairs of abundant aerations of biological contact tower of gas distribution section, equal and water quality guarantees microbic activity.The gas extractor 5 of cat head is collected gas simultaneously, is connected to other and uses the gas point, has practiced thrift the energy.
The body refuse and the waste water of the sludge drainage system collecting precipitation of tower bottom drain into the further concentration of settling system through shore pipe, have reduced the subsequent disposal sludge quantity.
The visual concrete water quality of biological contact oxidation tower water outlet, centralized collection is promoted to the biological contact oxidation tower internal recycle again with pump and handles, and reduces waste water COD.
This equipment can improve the level of automation and the plant factor of system greatly, reduces energy consumption and operating cost, has solved scum problem completely, has alleviated workman's operation intensity.
Above-mentioned these embodiments only are used to explain the utility model; But do not limit the scope of the utility model; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
