Detailed description of the invention
For the process demand to waste water particularly refuse leachate now, provide a kind of Waste Water Treatment.?
In this system, use the mode that combines with ozone of ultrasonic wave, carry out physics and chemical treatment, sufficiently simultaneously
Separate the harmful components in waste water, carry out high-frequency pulse voltage process further simultaneously, filter the huge sum of money in waste water
Belong to composition.
Refering to 1, the structural representation of one embodiment of the invention Waste Water Treatment.Waste Water Treatment includes:
First process pond 10, frees device and ozone flow in pipes 103 equipped with ultrasonic wave in the first process pond 10.
By introducing pipeline, waste water introducing the first process pond 10 typically by water leg, waste water enters
After first process pond 10, supersonic generator 101 is started working, and enters ultrasonic wave in water.Ultrasonic wave
After entering in water, cavitation effect can occur, cavitation effect can make various composition mixed at high speed internal in waste water,
There is provided good environment for the degraded of organic ammonia nitrogen composition and separation, and ultrasonic wave itself also can be in Decomposition Wastewater
Some impurity.Passing through ozone flow in pipes 103 injection of ozone in waste water, ozone has Strong oxdiative and makees simultaneously
With, can ammonia and nitrogen components in Decomposition Wastewater, owing to there being ultrasonic wave simultaneously so that ozone is in waste water
Oxidation carry out more thoroughly and fully.Through the double action of ultrasonic wave and ozone, the ammonia in waste water
The organic principles such as nitrogen are adequately broken, and have reached to promote the purpose of water quality.Process through the first process pond 10
Waste water, enters the second process pond 20.
Second process pond 20, processes the waste water after pond 10 is processed through described first, processes pond 20 second
In equipped with high-frequency pulse voltage generator.
After waste water enters the second process pond 20, open high-frequency pulse voltage generator 201, height is applied to waste water
Frequently pulse voltage.Under the effect of high-frequency pulse voltage, the heavy metal contaminants in waste water is removed.
3rd process pond 30, receives the waste water after the second process pond 20 is processed, and waste water processes pond the 3rd
MRB processing system 301 is utilized to carry out MRB process and carry out precipitation decomposition in 30, the 3rd process pond 30

The Acidity of Aikalinity of joint waste water, increases water quality further.
From the waste water processing through the 3rd process pond 30 it is believed that complete the process of waste water, discharge.
Further, as a new more specifically embodiment, above-mentioned each processes pond and collecting pit 40
It is all single, complete transfer in each pond for the waste water by arranging waterworks, it is also possible to switch valve is set
80 grades keep UNICOM and partition between pond.Ensure that waste water does not refluxes.
Further, before waste water enters collecting pit 40 or in collecting pit 40, doughnut is carried out to waste water
3012MBR process.Also other further purified treatment can be carried out.
In the first process pond 10, realize that ozone injects and waste water is discharged with the pipeline of a threeway.Ozone is sent out
The ozone that raw device 105 produces enters pipeline, extracts waste water out, enter ozone and inject bottom the first process pond 10
Pipeline 103, the ozone flow in pipes 103 producing ozone generator 105, water and ozone mix, by gas
Liquid mixing pump makes gas-liquid be sufficiently mixed, and is then passed through ozone flow in pipes 103 and injects in the first process pond 10
Waste water, pipeline can be extended to the bottom in the first process pond 10.Ozone flow in pipes 103 can be with
The waste outflow pipe UNICOM in one process pond 10, ozone flow in pipes 103 part in the first process pond 10 is led to
Cross three ports and receive the wastewater discharge pipe in the first process pond 10, drain into the second process pond 20.
A console 107 can be set on the side in the first process pond 10, be used for controlling ozone generator 105
And ultrasonic wave voltage generator.In the second process pond 20, the electric discharge of high-frequency pulse voltage generator 201
Plate 2012 can carry out modularized processing.For example the discharge electrode 2012 processing a waste water ability is made one
Module.Each module is independent, to realize carrying out block combiner flexibly for treating capacity.The control of radio-frequency generator
Part can hang over outside the pond in the second process pond, it is possible to is placed in console 107.Refering to Fig. 2, discharge electrode 2012
The top view of one module, is a fixing module in figure.
In the 3rd process pond 30, MBR processing system is set.Multiple back-shaped water pipe 3014 is set in pond,
On the water pipe of a reversion, connecting doughnut 3012 between the part on both sides, it is fine that waste water penetrates into hollow
Dimension 3012, enters into back-shaped water pipe 3014 by doughnut 3012.Top at each back-shaped water pipe 3014
Portion is provided with opening, connects collector pipe, each collector pipe be pooled at one the 3rd process pond 30 drainpipe,
To get rid of waste water.Can carry out extracting waste water to collector pipe by water pump.
It is additionally provided with gas-adding pipe in the second process pond 20 and the 3rd process pond 30, in waste water, inject air so that
Waste water can fully stir in pond.
Further regard to Fig. 3, collecting pit 40, described 3rd process pond 30 UNICOM can also be increased, receive warp
Cross the waste water after the described 3rd process pond 30 is processed to be collected；And
Fourth process pond (not shown), described fourth process pond and collecting pit 40 UNICOM, receive through collecting pit
Water in 40, Waste Water Treatment is discharged carry out reverse osmosis (RO) process to water therein after in this fourth process pond.
Further, in the build process of specific Waste Water Treatment, ozone can use the finished product of buying smelly
Oxygen, can install ozone generator 105 in present treatment system simultaneously further, and ozone generator 105 produces
Ozone injection of ozone flow in pipes 103.
In order to realize more preferable effect, referring to Fig. 4, the above waste gas of can setting up in the first process pond 10 is received
Ji Gai, because in the first processing procedure to waste water for the process pond 10, ammonia and nitrogen components has carried out sufficient decomposition,
Can produce the gases such as nitrogen, ammonia, and other impurity also can produce under the ultrasonic effect involving ozone other from
Waste water is separated, if these gases are directly discharged in air, then can air born pollution be increased useless
Abandon to collect and cover and can get up isolating gas collection from waste water by the escape pipe arranging on gas sampling lid
112 collect and process.
Further, the present invention implements to give the method that waste water is processed, and i.e. processes waste water in said system application
Method.
Refering to Fig. 5, the embodiment of the present invention processes the method flow diagram of waste water.
