Abstract
The invention provides a method using a coagulation air floatation machine to treat sewage. The method includes: the filtered and flocculently precipitated sewage is guided into the coagulation air floatation machine, and coagulant is added; the motor of the coagulation air floatation machine drives blades to rotate through a rotary shaft so as to allow the coagulant to have mixed reaction with the impurities in the sewage to form floc; an ultrasonic transmitter cavitates air entering the coagulation air floatation machine through an air inlet pipe to generate fine bubbles; the fine bubbles floats and adheres and carries away the floc during floatation; the floc floats to the water surface along with the fine bubbles and forms floating residues, the floating residues are removed, and the water treated by the fine bubbles is discharged from the water outlet in the bottom of the coagulation air floatation machine. The method has the advantages that the water treatment method is simple, low in cost and capable of effectively removing the impurities such as suspended particles, emulsified oil, fibers and heavy metal in the sewage, environmentally friendly, free of pollution and high in market application value.
Description
Technical field
The present invention relates to sewage treatment area, be specifically related to a kind of method utilizing coagulation air-float machine to process sewage.
Background technology
Along with the substantial amounts of rural population of China pours in city, urban population is continuously increased, and the water resource in city has suffered that heavy damage, China are faced with the problem that water resource is exhausted.Water resource is the guarantee that the mankind depend on for existence, and it is non-renewable resources, and it not only affects the productive life of people, more the national conditions state on China and transports and have important impact.As can be seen here, the city sewage treatment works strengthening China is very urgent.
Municipal sewage is mainly in city the sanitary sewage of discharge, industrial wastewater etc., and the sewage treatment plant after these waste water is mainly collected by the sewage network in city or through city enters water body after processing.In the last few years, the urban wastewater discharge of China had been continuously increased.And the wastewater pollution source of China mainly has industrial source, agricultural sources, urban life source and least a portion of centralized pollution facilities exhaust source, wherein, tool relevant information shows, town domestic sewage discharge capacity is to increase the main cause of China's quantity of wastewater effluent.As can be seen here, although China has set up many sewage treatment plants, the city sewage treatment works of China puts in place the most not.
21 century is the epoch that economy, science and technology develop rapidly, and interstate competition grows in intensity also with the quickening of economic globalization step.In order to occupy a tiny space between the world, China is constantly accelerating the urban construction process of China, takes part in international competition power improving the overall national strength of China.But, China but causes the serious problems of water resource pollution during urbanization, and this continuable development principle always advocated with China is runed counter to, the problem that China must solve urban water pollution by every means.
On the other hand, sewage is in the processing procedure of sewage treatment plant, first from flowing between coarse rack, after coarse rack removes bigger floating foreign material, then sewage is after fine fack removes tiny floating thing, in rotational flow grit chamber, remove silt, be deposited on the silt bottom setting pot in sand sucker enters sewage sludge storage pond；Sewage after desanding enters such as back-end processing facilities and equipment coagulative precipitation tank, the suspended solids thing in sewage mainly removed by coagulative precipitation tank, and through coagulation formed floc particle little, lightweight, sedimentation function is poor, this sewage disposal brings huge challenge.Therefore, invent a kind of sewage water treatment method and process the impurity of residual in the sewage after coagulative precipitation tank processes, to promoting that sewage disposal development and water conservation recycling are significant.
Summary of the invention
In order to solve prior art problem, the present invention provides a kind of method utilizing coagulation air-float machine to process sewage.The sewage water treatment method of the present invention is simple, and processing cost is low, can effectively remove the impurity such as the particle in sewage, oil emulsion, fiber, heavy metal, environment friendly and pollution-free, has wide market prospect and using value.
For solve solve prior art problem, the present invention by the following technical solutions:
A kind of method utilizing coagulation air-float machine to process sewage, it is characterised in that including following process step: processed by filtration, flocculation sediment by sewage, then introduce coagulation air-float machine, add coagulant, sewage, after coagulation air-float machine processes, obtains clear water；Described coagulant is one or more in aluminum sulfate, aluminium polychlorid, bodied ferric sulfate.
Further, coagulation air-float machine described in described coagulation air-float machine includes cavity, described cavity top is provided with water inlet, block it is arranged at intervals with on cavity inner wall, cavity bottom is provided with outlet, cavity top is provided with motor, described motor is connected with impeller by the rotating shaft of inside cavity, at least two panels blade it is provided with on impeller, described rotating shaft is provided with air inlet pipe, air inlet pipe one end and external connection, the air inlet pipe other end is connected with inside cavity by impeller, the bottom inside of cavity is provided with ultrasonic transmitter, and described ultrasonic transmitter is in the underface of impeller.
Further, described in be filtered into grid filtration, the grizzly bar gap of grid is 5-20mm.
Further, described coagulation air-float machine blade working rotating speed is 200-800rpm；
Further, described blade has micropore, micropore size 0.1-0.3mm, increases micro air bubble quantity of formation, make micro air bubble be formed evenly.
Further, the addition of described coagulant is 40-120mg/L.
Coagulation air-float machine such as Fig. 1 of the present invention.
The present invention utilizes the principle of the method for coagulation air-float machine process sewage: the motor of coagulation air-float machine is rotated by the blade in rotating shaft impeller, simultaneously because the concussion effect that block plays, makes coagulant be more easy to hybrid reaction with the impurity in sewage, forms flco；And ultrasonic transmitter not only makes the air cavitation being entered coagulation air-float machine by air inlet pipe form micro air bubble, micro air bubble sticks flco, makes flco proportion be less than water, thus floats together with micro air bubble；Simultaneously because cavitation, make the surface of dirty impurities in water by destruction drastically, be more easy to be taken away removing by micro air bubble.
A kind of method utilizing coagulation air-float machine to process sewage of the present invention, compared with prior art, has and highlights substantive features and significant advantage as follows:
1. the present invention is rotated by the blade of coagulation air-float machine and the concussion effect of block, can promote the combination of coagulant and impurity, improves air flotation effect；
2. due to the fact that the micro air bubble of coagulation air-float machine produces via ultrasonic transmitter cavitation, make micro air bubble quantity increase, and diameter is little and uniform, and flco is more effectively removed by floating under the common effect of micro air bubble, ultrasound wave and baffle plate；
3. the sewage water treatment method of the present invention is simple, and low cost can effectively remove the impurity such as the particle in sewage, oil emulsion, fiber, heavy metal, environment friendly and pollution-free, has wide market using value.
