Description
Technical field
The present invention relates to the purified treatment engineerings of the industries waste water such as such as printing and dyeing, chemical industry, plating, coking, belong at environment-protective water
Reason field is related specifically to a kind of fast demountable biological selector.
Background technique
The principle for the biological selector that the present invention uses are as follows: the growth of active microorganism all meets Monod equation in sludge:
The KS(saturation constant of most of der Pilzs) and μm ax(microorganism in saturated concentration maximum Specific incremental rate) value is than bacterium glue
Group bacterium is low.Der Pilz according to Monod equation with low KS and μm ax value has high growth under the conditions of low substrate concentration
Rate, and the Zoogloea bacteria with higher KS and μm ax value is just dominant under Super matrix concentration conditions.In substrate concentration height
When zoogloea matrix be higher than der Pilz using rate, therefore can use the culture Zoogloea bacteria of matrix motive force selectivity
And limit the growth of der Pilz.Biological selector can be set before aeration tank according to this principle, i.e., be arranged in aeration tank front end
High load capacity mixed zone is effectively to inhibit der Pilz growth in practical applications at present, prevents that SVI from increasing and sludge bulking relatively has
The method of effect.
A kind of Chinese Patent Application No. are as follows: CN2015201891107, title are as follows: life for city domestic sewage processing
Object selector.Rectangle water distributing trough is mounted on the middle position of outer pool wall length direction, water inlet pipe by the structure of the biological selector
It is mounted on outer pool wall and is connected to the direction of rectangle water distributing trough, the aerobic mixed liquor of biological selector can be increased and water inlet is abundant
The problem of mixed effect difference.More complicated but there are installment works, effect is undesirable, the relatively high problem of cost.
Summary of the invention
1, technical problem to be solved:
In view of the deficiencies of the prior art, the present invention provides a kind of fast demountable biological selector, for pointedly right
High load capacity mixed zone is set before aeration tank, effectively inhibits der Pilz growth, prevents SVI raising and sludge bulking, so that enhancing is set
Standby regulation effect.The biochemical system that need to be transformed is accomplished without clear pond, it is only necessary to which the time of a small amount of installment work, operation is short.And
And sewage is under distributor effect and sludge mixing is more abundant, and it is excessively high to avoid local load.
2, technical solution:
A kind of fast demountable biological selector, including processing pond, water inlet pipe, outlet pipe.The water inlet pipe is located at processing
The top in pond and across the upper end in processing pond；Water inlet pipe connects water dispensing apparatus；The water dispensing apparatus is the spray of at least two spirals
Waste water is discharged into processing pond by head, the spiral nozzle, and the processing pond is filled with filler；Outlet pipe is located at processing bottom of pond portion.
The present invention is simple for structure, can select existing processing pond top layout across at the top of processing pond into
Water pipe, hydraulic pressure when spraying liquid using spiral nozzle, which is unevenly distributed, drives not arrheaing for liquid in processing pond to move so as to reach
To the purpose as a biological selector, the load of biological selector is reduced.The effect of present apparatus selection spiral nozzle is choosing
The spiral nozzle of dress can not only be by sewage spurting into processing pond more evenly, and can be formed not in the pre-mix zone of processing pond
Same hydraulic pressure；Different hydraulic pressure can accelerate the flow velocity of the water of pre-mix zone to increase the efficiency of sewage treatment, increase biology choosing
It selects the aerobic mixed liquor of device and water inlet is sufficiently mixed effect.
Further, the present apparatus further includes mud return line.The mud return line is located at the pool wall of processing pond.
Further, the spiral nozzle water outlet diameter is different.In order to further enhance biological selector in processing pond
Aerobic mixed liquor and water inlet are sufficiently mixed effect, and the water outlet diameter of the spiral nozzle of present apparatus selection is different.
Further, the height of the spiral nozzle water outlet is different.The injection well downhole flow regulator selected in the present apparatus is spiral nozzle,
By different from the coupling part of the water inlet pipe freeboard different in size for allowing spiral nozzle in each spiral nozzle, processing pond is allowed
The middle aerobic mixed liquor of biological selector is sufficiently mixed with water inlet.
3, the utility model has the advantages that
(1) the configuration of the present invention is simple can accomplish the biochemical system that need to be transformed to be not necessarily to clear pond, it is only necessary to a small amount of soil
Building work can be completed, and the present apparatus can be mounted directly at the top of existing processing pond can play the work of biological selector
With.
(2) present invention is convenient for disassembly and assembly, helps to replace the filler in processing pond.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention,
Fig. 2 is the structural schematic diagram for the spiral nozzle that the present invention uses.
Specific embodiment
1 the present invention will be described with reference to the accompanying drawing.
The sewage that chemical company generates enters water inlet pipe, and the water dispensing apparatus being connected with water inlet pipe uniformly sprays sewage
It into processing pond, is sprayed by water distribution structure, so that the liquid of pre-mix zone accelerates flowing stirring, the flowing of liquid is made not need to move
Power supports.Liquid is reacted with the filler in processing pond, and last processed water enters aeration tank by outlet pipe.
It is as shown in Fig. 1 the present invention: a kind of fast demountable biological selector, including processing pond 5, water inlet pipe 1, water outlet
Pipe 2.The water inlet pipe is located at the top of processing pond and across the upper end in processing pond；Water inlet pipe connects water dispensing apparatus；It is described to match
Water installations are at least two spiral nozzles 3, and waste water is discharged into processing pond by the spiral nozzle, and the processing pond is filled with filler
6；Outlet pipe is located at processing bottom of pond portion.The item number of water inlet pipe is configured as needed.
The present apparatus further includes mud return line 4.The mud return line is located at the pool wall of processing pond, and lower than distributor
Water outlet.Very easily mud can be cleared up.
It is as shown in Fig. 2 the structure chart of spiral nozzle.The spiral nozzle water outlet diameter used in the present invention can not
Same, spiral nozzle water outlet height is different.It is aerobic that biological selector in processing pond can be further enhanced by above-mentioned selection
Mixed liquor and water inlet are sufficiently mixed effect, and the aerobic mixed liquor of biological selector in processing pond is allowed to be sufficiently mixed with water inlet.
Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe
This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention
Shield range should be subject to what claims hereof protection scope was defined.
