Description

Micro air floatation system
Technical Field
The utility model relates to a sewage treatment device technical field, more specifically say, relate to a miniature air supporting system.
Background
The rural domestic sewage treatment is to remove and degrade harmful substances and polluted environment components in the domestic sewage for harmless treatment. The rural domestic sewage treatment mainly considers selecting mature and reliable technology suitable for rural characteristics and practical sewage treatment application technology, and in recent years, rural domestic sewage treatment processes are different but are different combinations of unit treatment technologies. The rural sewage treatment practical technology comprises a septic tank, a sewage purification methane tank, a common aeration tank, a sequencing batch bioreactor, an oxidation ditch, a biological contact oxidation tank, an artificial wetland, land treatment, an ecological pond and the like. In the prior art, the air flotation separation technology is that air and water are dissolved into water to the utmost extent under a certain pressure condition, the air and the water are strived to be in a saturated state, then the formed pressure dissolved air water is released through decompression to generate a large amount of micro bubbles which are fully contacted with suspended flocs in the water, so that the suspended flocs in the water are adhered to micro bubbles and float to the water surface along with the bubbles to form scum, and the scum is scraped, so that the water quality is purified. The air-float water purifying technology is widely applied at home and abroad. The air flotation device applied in China has a dispersed air flotation method, an electrolytic air flotation method, a pressure dissolved air flotation method and the like, but the equipment has higher power and lower release concentration generally and can not meet the requirement of rural sewage treatment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a miniature air supporting system, this system compare with current air supporting system, have the power low, release concentration advantage such as big, especially are fit for supporting rural area's integration sewage treatment device and use.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides a miniature air supporting system, includes the controller, dissolves gas pitcher, releaser and air supporting pond, the controller have the air water pump of dissolving through the line connection, the air water pump of dissolving pass through the pipeline respectively with the air supporting pond with dissolve the gas pitcher intercommunication, wherein be located and be equipped with the end of intaking on the inside pipeline of air supporting pond, the gas pitcher top of dissolving intake and be equipped with the pneumatic valve on the pipeline, the pneumatic valve pass through the circuit and be connected with the controller, the air outlet end of dissolving gas pitcher below be connected with the releaser, the releaser go deep into inside the air supporting pond.
Furthermore, the controller and the dissolved air water pump are externally connected with a working power supply.
Further, the outer end of the air inlet pipeline is connected with an air compressor, and the air compressor is connected with the controller through a circuit.
Furthermore, the micro air floatation system is integrated in the integrated sewage treatment equipment.
Compared with the prior art, the utility model has the advantages that:
the utility model discloses in control respectively through the controller and dissolve gas water pump and air compressor collaborative work, will add pressure water and mix with the air dissolving the gas pitcher, have power low, release concentration advantage such as big.
Drawings
FIG. 1 is a schematic view of the connection structure of the components of the present invention;
in the figure: 1. a dissolved air water pump; 2. a controller; 3. an air valve; 4. an air floatation tank; 5. a dissolved air tank; 6. a releaser; 7. a water inlet end.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the utility model easy to understand and understand, the utility model is further explained by combining with the specific figures.
As shown in fig. 1, a miniature air supporting system, including controller 2, dissolve gas pitcher 5, releaser 6 and air supporting pond 4, controller 2 has dissolved air water pump 1 through the line connection, dissolved air water pump 1 communicates with air supporting pond 4 and dissolved gas pitcher 5 respectively through the pipeline, wherein be located and be equipped with into water end 7 on the inside pipeline of air supporting pond 4, be equipped with pneumatic valve 3 on the air inlet pipeline of dissolved gas pitcher 5 top, pneumatic valve 3 is connected with controller 2 through the circuit, it is connected with releaser 6 to dissolve 5 below water ends of gas pitcher, releaser 6 is deepened inside air supporting pond 4, controller 2 and the external working power supply of dissolved air water pump 1, the air inlet pipeline outer end is connected with air compressor, air compressor passes through the circuit and is connected with controller 2, miniature air supporting system integration is inside integration sewage treatment device of integration.
During actual installation, the equipment parts are connected in sequence, wherein the air floatation device mixes part of treated clear water (the design index is 20-40%, usually 30%) with air in the dissolved air tank 5 through the dissolved air water pump 1, the air is dissolved in the water, and the dissolved air efficiency reaches over 80%; the air in the dissolved air tank 5 is controlled by an air compressor machine through a controller 2, the air is automatically supplemented into the dissolved air tank 5, the dissolved air water from the dissolved air tank 5 passes through a releaser 6, the pressure of the dissolved air water is reduced to be released, the pressure of the dissolved air water is reduced to zero or negative pressure, the air dissolved in the water is filled with water and released, micro bubbles with the particle size of 20-50um are formed, the micro bubbles are combined with suspended matters in sewage, part of the micro bubbles directly grow in the suspended matters of the micro air floatation machine, the specific gravity of the suspended matters in the sewage is reduced until a large amount of floating slag is formed on the surface of a floating water body, then the floating slag is removed by a foam scraping machine, clean water at the lower part of an air floatation tank 4 passes through a clean water collecting pipe and enters the air floatation clean water tank, and then the clean water can be directly discharged outwards.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
