Abstract
The utility model relates to a waste water treater. The utility model has the structure that a plurality of jet flow ejectors are arranged at the upper part of a sealed circular cylinder, and an air pressure regulating tube is arranged at the top of the circular cylinder. By utilizing mechanical shearing force, the utility model effectively disintegrates the air mixed in the waste water into minute air bubbles which then enter a ladder diffusion tube to convert kinetic energy into potential energy to further increase the dissolvability of the air in the water, and finally, the minute air bubbles enter a flotation tank to separate the air from the water. The sludge floating slag which floats up to the water surface is eliminated by a sludge scraper, and the clear water is overflowed and discharged through an overflow plate. A small amount of sludge deposited at the bottom of a groove flows back through a return conduit to carry out the secondary treatment. The utility model has the advantages of small occupation area, less investment and high efficiency of processing the waste water and is an ideal waste water treater.
Description
The utility model relates to a kind of wastewater treatment machine, particularly a kind of equipment that utilizes the air supporting method to handle waste water.
Existing waste paper pulp-making waste water, mthod of white water from paper making, sugar production wastewater, dissolved air floatation equipment and technology are mainly adopted in the processing of leather waste water and dyeing waste water, its principle is under the stressed outside situation, air is dissolved in the state that reaches capacity in the waste water in dissolving, discharge with atomic little bubble, the suspended particle in the waste water with its come-up, forms foam on every side with regard to adhering to bubble on the water surface of air flotation pool, remove by scraper then, waste water is purified.The shortcoming of this equipment is that power consumption is big, running cost is high, and the mud separating effect is relatively poor, and investment is bigger.
The purpose of this utility model provides that a kind of floor space is little, reduced investment, easy and simple to handle, working cost is low, treatment effect is good jet air float waste waster processor.
The utility model is realized by following mode: the jet air float waste waster processor is by the cylinder of a sealing and be contained in the rising pipe of air pressure adjustment pipe, bottom at some jet ejectors, the top of its inside and parts such as air flotation pool constitute, and industrial sewage is entered by the inlet spray tube of jet ejectors.The outlet of jet ejectors lead to sealing cylinder and with the inwall tangentially of cylinder, jet ejectors is made up of case of sprayer, spray tube, gas inlet pipe and spout, the opening of spray tube is at the intravital middle part of shell.Air flotation pool comprises cell body, water inlet pipe, clear water output pipe and mud scraper, sewage backflow pipe, and water inlet pipe is the ladder diffuser tube, and sand setting ditch and return line are arranged at the cell body bottom.
Spray the simplified waste water that comes out from jet and enter air flotation pool, the structure of air flotation pool is to establish some ladder diffuser tubes to reach the effect of eliminating function at the waste water entrance end, the secondary flow deflector is then arranged, guarantee that the suspended particle come-up is effective, mud scraper is installed in the top of air flotation pool, to scrape off the mud scum silica frost that floats to the water surface from the air flotation pool upper surface, mud is discharged by the mud discharging machine, again reuse after clear water is discharged outside the air flotation pool by outlet pipe, the tail end of air flotation pool can be established splash pan, prevents that the mud that floats from flowing out with clear water.
The principle of above-mentioned jet air float waste waster processor is to utilize mechanical shear stress, is ground into tiny bubble effectively and carries out flotation being mixed in air in the waste water.Promptly the high-speed waste water that is penetrated by nozzle makes suction chamber form negative pressure, and from tail pipe suction air, after entering the trunnion section, the gas-vapor mix body carries out fierce energy exchange, air is ground into micro-bubble, enters diffusor (expansion section) then, and kinetic energy is converted into potential energy, further compressed bubble, increased the solubleness of air in water, entered at last and carry out aqueous vapor separation, i.e. floatation process in the flotation cell.In floatation process, with the suspended solid of a large amount of micro-bubbles, in the body of pond, rise reposefully in the waste water, reach the water surface after suspended solid just rely on these bubbles to support and maintain the water surface, and scraped exit end to section between cleaning shoe from inlet section, again it is pushed the mud discharging pipeline.After entering overflow groove, the outlet by spacer plate below of purifying waste water of isolating suspended solid discharges clean water basin.
The utility model has the advantages that:
1. equipment manufacturing cost is low, than existing settling pond and air flotation pool reduced investment.
2. working cost is low: the power consumption of system is extremely low, only gets final product with 0.75-2kw, and drug dosage is few, and processing cost is no more than 0.25 yuan/m
3, take all factors into consideration, can also produce certain economic benefits.
3. treatment effect is good: the SS clearance is more than 98%, and the COD clearance is more than 75%, and the draining of outlet reaches national requirements, can be used as water coolant or water of productive use reuse.
4. simple to operate: total system only needs a worker management, and simple to operate, labour intensity is extremely low, and maintenance cost is low, and easy disassembling is convenient to maintenance.
5. floor space is little: floor space is no more than 40m
2, and equipment is installed easily and is moved.
6. it is big to handle the water yield: the process range of this system is big, can handle 50-500m
3The waste water of/h.
7. wide accommodation: this system not only can handle paper mill effluent, can also handle sugar production wastewater, dairy industry waste water effectively, meat processing waste water, refinery water, chicken processing waste water, food processing wastewater, leather waste water and dyeing waste water etc.
