Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a method of utilizing coagulation air-float machine treated sewage.
Background technology
As a large amount of people in the countryside in China pour in city, urban population is continuously increased, and the water resource in city is by tight
It destroys again, China is faced with the problem of water resource exhaustion.Water resource is guarantee for the survival of mankind, it is non-renewable money
Source, it not only influences the production and living of people, more has important influence to the national conditions state in China fortune.It can be seen that reinforcing
The city sewage treatment works in China are very urgent.
Municipal sewage is mainly the sanitary sewage discharged in city, industrial wastewater etc., these waste water mainly pass through city
The sewage network in city is discharged into water body after collecting rear or sewage treatment plant's processing by city.In recent years, the city in China
City's quantity of wastewater effluent is being continuously increased.And the wastewater pollution source in China mainly has industrial source, agricultural sources, urban life source and lacks
Partial centralization pollution facilities exhaust source, wherein tool relevant information shows that town domestic sewage discharge capacity is to increase China's dirt
The main reason for water discharge capacity.It can be seen that although China has set up many sewage treatment plants, the municipal sewage treatment work in China
Make still not enough in place.
21 century is the epoch of economic science and technology rapid development, and inter-State competition is also with economic globalization step
Quickening grow in intensity.In order to occupy a tiny space between the world, China constantly accelerate China urban construction process,
Overall national strength to improve China takes part in international competition power.However, China but causes water resource pollution during urbanization
Serious problems, this is runed counter to the continuable development principle that China is advocated always, and China must solve city by every means
The problem of city's water pollution.
On the other hand, sewage first between flowing into coarse rack, removes in the processing procedure of sewage treatment plant through coarse rack
After larger floating sundries, then sewage removes silt after fine fack removes tiny floating material in rotational flow grit chamber, deposits
Silt in setting pot bottom is discharged into through sand sucker in sewage sludge storage pond；Sewage after desanding enters as back-end processing facility is set
Standby coagulative precipitation tank, coagulative precipitation tank mainly remove the suspended solid particles object in sewage, and through the floc particle of coagulation formation
It is small, light-weight, sedimentation function is poor, this sewage disposal brings huge challenge.Therefore, it is next to invent a kind of sewage water treatment method
Processing is through remaining impurity in coagulative precipitation tank treated sewage, to promoting sewage disposal development and water conservation to repeat profit
With being of great significance.
Invention content
In order to solve prior art problem, the present invention provides a kind of method using coagulation air-float machine treated sewage.This hair
Bright sewage water treatment method is simple, and processing cost is low, can effectively remove suspended particulate, oil emulsion, fiber, heavy metal in sewage
Equal impurity, it is environment friendly and pollution-free, have a vast market foreground and application value.
To solve prior art problem, the present invention uses following technical scheme：
A method of utilizing coagulation air-float machine treated sewage, which is characterized in that including following processing step：Sewage is led to
Filtering, flocculation sediment processing, then introduce coagulation air-float machine, and coagulant is added, and sewage obtains after the processing of coagulation air-float machine
Clear water；The coagulant is one or more in aluminum sulfate, aluminium polychloride, bodied ferric sulfate.
Further, coagulation air-float machine described in the coagulation air-float machine includes cavity, and the cavity top is provided with into water
Mouthful, block is arranged at intervals on cavity inner wall, cavity lower part is provided with water outlet, motor, the motor are provided at the top of cavity
It is connect with impeller by the shaft of inside cavity, at least two panels blade is provided on impeller, air inlet is provided in the shaft
Pipe, air inlet pipe one end and external connection, the air inlet pipe other end are connect by impeller with inside cavity, and the bottom inside of cavity is equipped with
Ultrasonic transmitter, the ultrasonic transmitter is in the underface of impeller.
Further, described to be filtered into grid filtration, the grizzly bar gap of grid is 5-20mm.
Further, the coagulation air-float machine blade working rotating speed is 200-800rpm；
Further, micropore, micropore size 0.1-0.3mm increase micro air bubble forming quantity, make on the blade
Micro air bubble is formed evenly.
Further, the addition of the 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 treated sewage：The motor of coagulation air-float machine is driven by shaft
Blade rotation on impeller, simultaneously because the concussion that block plays the role of, makes coagulant be more easy to mix instead with the impurity in sewage
It answers, forms flco；And ultrasonic transmitter not only makes the air cavitation for entering coagulation air-float machine by air inlet pipe form fine gas
Bubble, micro air bubble stick flco, and flco proportion is made to be less than water, to float together with micro air bubble；Simultaneously because cavitation,
Make the surface of dirty impurities in water by destruction drastically, is more easy to take away removing by micro air bubble.
A kind of method using coagulation air-float machine treated sewage of the present invention has following prominent compared with prior art
Substantive features and notable advantage：
1. the present invention is acted on by the rotation of the blade of coagulation air-float machine and the concussion of block, coagulant and impurity can be promoted
In conjunction with raising air flotation effect；
2. the present invention makes micro air bubble since the micro air bubble of coagulation air-float machine is generated via ultrasonic transmitter cavitation
Quantity increases, and diameter is small and uniform, and flco more effective quilt under the collective effect of micro air bubble, ultrasonic wave and baffle
It floats and removes；
3. the sewage water treatment method of the present invention is simple, at low cost, can effectively remove suspended particulate in sewage, oil emulsion,
The impurity such as fiber, heavy metal, it is environment friendly and pollution-free, have a vast market application value.
