Summary of the invention
It is an object of the invention to provide and a kind of multiple types sewage can be carried out early stage pretreatment and/or last advanced treating, float and the high sewage separating device of COD clearance.
The above-mentioned technical purpose of the present invention has the technical scheme that
A kind of sewage separating device, including water inlet pipe, its described water inlet pipe one end connects first class pressure device;The described water inlet pipe other end connects to be had drain separator and connects with the secondary pressure pipe being arranged in described drain separator;Described secondary pressure pipe is provided above being positioned at the three stage pressure districts on described drain separator top;
It is provided with bubble sludge blanket accommodating area between described secondary pressure pipe and described three stage pressure districts;Around described secondary pressure pipe height interval in and to be positioned at below described bubble sludge blanket accommodating area be two grades of clear water accommodating areas;Described side, bubble sludge blanket accommodating area and be positioned at outside described drain separator and be provided with the first sewage draining exit;
Described three stage pressure districts are provided above exhalant region;
Described secondary pressure pipe and three stage pressure districts are connected to pressure control device.
Arranged by present configuration, form three stage pressure districts, and reserved place, the sludge blanket of self-assembling formation fine and closely woven bubble supporting after plant running, float and COD clearance are high between secondary pressure pipe and three stage pressure districts.
Adding medicine while water feeding of water pump, such as alkali, acid, flocculation agent and some specific material;Arrive Pressure chamber after carrying out vigorous reaction, then require discharge according to former water or water outlet or carry out advanced treating.This device municipal wastewater, wastewater from chemical industry, butcher, food, papermaking, weave, print and dye, leather, plating, PETROLEUM PROCESSING, chemical fibre, paint, rubber, medicine and other fields have sewage disposal purposes widely, float is removed including fish pond, all kinds of sewage can be carried out early stage pretreatment and last advanced treating by oxygen supplement and sterilization;Float and COD clearance are high.Need to control pressure size according to actual water quality and operation, reach float and the high requirement of COD clearance.
As preferably, it is provided with two grades of clear water between described two grades of sides, clear water accommodating area and described bubble sludge blanket accommodating area and introduces pipe.
Two grades of clear water introduce pipe and filter further hence into three stage pressure districts (filter material layer district) for two grades of clear water of a part are introduced sludge blanket top layer, improve separation efficiency.
As preferably, described exhalant region includes being arranged on the outlet pipe outside described drain separator.
As preferably, described two grades of clear water accommodating areas and be positioned at below described drain separator outside and be provided with the second sewage draining exit.
As preferably, in described exhalant region, it is provided with water outlet high density microvesicle injection apparatus.
As preferably, described water outlet high density microvesicle injection apparatus is jet-flow air-floatation apparatus.
As preferably, described jet-flow air-floatation apparatus includes at least two liquid-gas jet device and the dissolving communicated with described liquid-gas jet device.
As preferably, described water outlet high density microvesicle injection apparatus is externally connected with micro-filtration membrane processing means or ultrafiltration membrane treatment device or film bioreactor device.
According to actual raw water quality and effluent quality requirement, micro-filtration membrane processing means or ultrafiltration membrane treatment device or film bioreactor device are set further, meet the demand of Water condition occasion.
As preferably, described three stage pressure districts are filter material layer district.
In sum, the method have the advantages that and arranged by present configuration, adding medicine while water feeding of water pump, such as alkali, acid, flocculation agent and some specific material;Arrive Pressure chamber after carrying out vigorous reaction, then require discharge according to former water or water outlet or carry out advanced treating.This device municipal wastewater, wastewater from chemical industry, butcher, food, papermaking, weave, print and dye, leather, plating, PETROLEUM PROCESSING, chemical fibre, paint, rubber, medicine and other fields have sewage disposal purposes widely, float is removed including fish pond, all kinds of sewage can be carried out early stage pretreatment and last advanced treating by oxygen supplement and sterilization;Float and COD clearance are high.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As it is shown in figure 1, a kind of sewage separating device, including water inlet pipe 0, its water inlet pipe 0 one end connects first class pressure device 1;Water inlet pipe 0 other end connects to be had drain separator 10 and connects with the secondary pressure pipe 2 being arranged in drain separator 10;Secondary pressure pipe 2 is provided above being positioned at the three stage pressure districts 3 on drain separator 10 top;It is provided with bubble sludge blanket accommodating area 4 between secondary pressure pipe 2 and three stage pressure districts 3;Around secondary pressure pipe 2 height interval in and to be positioned at below bubble sludge blanket accommodating area 4 be two grades of clear water accommodating areas 5;Bubble sludge blanket side, accommodating area 4 and be positioned at that drain separator 10 is outside is provided with the first sewage draining exit 41;Three stage pressure districts 3 are provided above exhalant region 6;Secondary pressure pipe 2 and three stage pressure districts 3 are connected to pressure control device 7.Three stage pressure districts (3) can select suitable filtrate as filter material layer district.
It is provided with two grades of clear water between two grades of sides, clear water accommodating area 5 and bubble sludge blanket accommodating area 4 and introduces pipe 51.Exhalant region 6 includes the outlet pipe 61 being arranged on outside drain separator 10.Two grades of clear water accommodating areas 5 and be positioned at below drain separator 10 outside and be provided with the second sewage draining exit 52.Water outlet high density microvesicle injection apparatus 61 it is provided with in exhalant region 6.Water outlet high density microvesicle injection apparatus 6 can be jet-flow air-floatation apparatus, and jet-flow air-floatation apparatus can be to include at least two liquid-gas jet device and the dissolving device (being not shown) communicated with liquid-gas jet device.
In order to reduce related substances content in discharge water further, improve discharge water quality standard, can connect further outside water outlet high density microvesicle injection apparatus 61 and have micro-filtration membrane processing means or ultrafiltration membrane treatment device or film bioreactor device 8.
Use apparatus of the present invention that dyeing waste water is processed, the results are shown in Table 1.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in scope of the presently claimed invention.
