Description

The pure oxygen apparatus for treating sewage

The utility model relates to a kind of waste disposal plant.

Existing waste disposal plant generally is provided with equalizing tank, preliminary sedimentation tank, settling tank, oxidation pond, sterilization pool, sludge sump, can separate between each pond, also can connect together, domestic oxidation pond adopts blast aeration, and 79% component is water-fast nitrogen in the air.Therefore, a large amount of foul smell of when sewage disposal, can overflowing, general 10 tons of sewage of the every processing of biochemical treatment system will be emitted 5m at least ³Foul smell solves when water pollutes and has really caused atmospheric pollution, is unfavorable for the integrated environment protection.The waste disposal plant that adopts pure oxygen aeration is arranged, but the equipment complexity costs an arm and a leg abroad, need usually with four pumps runnings, and pipeline is long, easily obstruction, is not suitable for China's characteristics.

The purpose of this utility model provides a kind of pure oxygen apparatus for treating sewage, makes the treatment system simplified equipment, only just can finish water yield adjusting, mud backflow automatically with a pump, and polluted air is not economical and practical.

The technical solution of the utility model is:

The pure oxygen apparatus for treating sewage comprises the sewage lagoon that is provided with the water inlet pipe mouth and the draining mouth of pipe, is located at sump pump in the sewage lagoon, contains the sewage treatment pot of settling tank and sludge sump, and it is characterized in that: sewage lagoon water inlet pipe mouth place is provided with and cuts dirty basket; Divide three sections in the sewage treatment pot, the stage casing is a settling tank, one end is a mixing pit, the other end is a sludge sump, mixing pit and settling tank bottom communicates, and has shore pipe to be communicated with between settling tank and the sludge sump, is communicated with by overflow adjustable pipe, waste pipe, clear water pipe between sewage lagoon and the sewage treatment pot, the overflow adjustable pipe crosses sewage treatment pot, and the water surface that mouth is separately positioned on settling chamber, mud room, mixing section is regulated in three overflows; Waste pipe outlet is located at the place that communicates, settling chamber bottom mixing section; The end of clear water pipe links to each other with one section perforation header that is located at settling chamber's water surface;

Link to each other with the threeway gas dissolver that the micropore plug is housed by flexible pipe between waste pipe and the sump pump, threeway gas dissolver and the oxygen hose that is connected oxygen generator connect; Mud return channel of exit end cover of waste pipe;

The outlet of clear water pipe is arranged on the overflow groove of sewage lagoon, and overflow groove communicates with water shoot, and the aquifer yield of clear water pipe is controlled by float(ing)valve.The ball float of float(ing)valve connects a lever and pressure bar.

Can establish inclined tube, filler, disinfect box in the settling tank.

Sewage lagoon and sewage treatment pot are that glass reinforced plastic, metal or plastic material are made.

Pipe is a nozzle in the mud return channel of waste pipe, and outer tube is tapered pipe.

Working process of the present utility model is:

Sanitary sewage or kin other sewage flow into hold well 2 through cutting 3 sections dirty sand settings of dirty basket by waste pipe 1, deliver to dissolved oxygen in the gas dissolver 6 by sump pump 4 by flexible pipe 5; Oxygen is produced by oxygen generator 8, is delivered to the oxygen inlet that micropore disperse plug 10 is housed of gas dissolver by oxygen hose 9; Sewage is delivered to the mixing section of sewage treatment pot by mud return channel 11 behind the abundant dissolved oxygen in gas dissolver, in mixing section 12, remove pollutent, partially mixed then liquid flows into settling chamber 13, and another part mixed solution is regulated mouth 14 by the mixing section overflow and flowed back to dirty this well 2; In the settling chamber, get clear water by perforation header 15 collection, regulate mouthful 16 collection by overflow and get issuable scum silica frost; A mud part that precipitates enters mud return channel 11 and returns mixing section, and another part is sucked mud room 18 by shore pipe 17 and carries out slaking, after concentrating, regularly takes away by taking out dung-cart; The mud room supernatant liquor is regulated mouth 19 from overflow and is flowed back to hold well 2, produces spoil disposal suction by the overflow effect.Regulate overflow respectively and regulate the mouth of pipe height and the float(ing)valve 20 of mouth 14,16,19, be may command activated sludge concentration, reflux ratio, sludge volume, hold well water level, clear water output, make the Inlet and outlet water total amount self-poise of total system, after system reaches optimum Working, i.e. operation continuously automatically.

When the utility model was installed, with hold well inlet tube and outlet tube and outside water-in and water-out pipe coupling, sewage treatment pot can be arranged on the ground, also can be embedded in underground.Only need a few days once to clear up and cut dirty basket, at ordinary times need not personal management to taking mature sludge away annually half a year, sewage automatic overflow discharging when accident or maintenance.

The utility model has the advantages that: do not produce foul smell, no atmospheric pollution; Do not establish equalizing tank, quantities is little, reduces by 40% than the existing installation investment, takes up an area of and reduces 30%; Waterpower self-control self-regulated, reliable, do not need on duty; The molten gas of pure oxygen, the efficient height, energy-conservation more than 20%; Automatically operation installs, safeguards, manages simple.Be applicable to sanitary sewage such as factory of school of restaurant, residential area sanatorium and industrial organic waste water with handling.
