Along with the raising of people's living standard and developing rapidly of industry, kind and the quantity of waste water also increase thereupon, especially chemical industry, dyestuff, medicine, agricultural chemicals, rubbish transudate etc., they enter water body and cause serious pollution to environment, waste water wherein containing a large amount of difficult degradation, the common feature of this kind of waste water is high COD, high salinity, low BOD, adopts conventional chemical purification method process to be difficult to technology and the economic requirement that maybe cannot meet purifying treatment.At present in process used water difficult to degradate method, conventional employing method of evaporation, its investment is large, and running cost is high, more than 100 yuan, water per ton, makes these methods can not carry out spread aborning.
The principle of advanced oxidation processes process adopts the strong oxidizing property of hydroxyl radical free radical to process macromolecule organic in trade effluent.Usual employing diverse ways produces hydroxyl radical free radical, as Fenton reagent, electrolytic solution, ozone etc., again by hydroxyl radical free radical and organism generation oxidizing reaction, thus reach the object of decomposing organic matter, macromolecule organic is decomposed into can the small organic molecule of subsequent biochemical process.But the COD that the shortcoming of employing advanced oxidation processes is processed waste water can not arrive emission standard completely.
The principle of positive infiltration technology is: the solution placing two kinds of different concns on the both sides of a skim, because the characteristic of water, water molecules can pass this tunic by nature, and the side low from concentration is moved to the side that concentration is high.Compared with reverse osmosis, positive infiltration technology achieves the naturally osmotic of water by semi-permeable membranes, and energy consumption is low, does not need extraneous pressure can realize the sepn process of water molecules and macromole virus, bacterium; Material itself has water-wet behavior, effectively can prevent fouling membrane; The rate of recovery is up to 90%.But also have 10% concentrated solution not discharge, real zero release can not be realized.
Utility model content
In order to solve the problem, the utility model provides the energy-efficient treatment device of a kind of indegradable industrial effluent and sanitary sewage, and the waste water after process reaches the requirement of truly zero release, can directly discharge, there is working cost low, processing efficiency be high, energy consumption is low, the feature of green non-pollution.
The technical solution adopted in the utility model is:
An energy-efficient treatment device for indegradable industrial effluent and sanitary sewage, comprises settler, catalyst-assembly, advanced oxidation device, positive permeator, water-freeing arrangement.
On the right side of described settler, sewage outlet is set; Wastewater inlet and precipitant inlet are set above described settler; The outer discharge pipe of mud is set bottom described settler; The outer discharge pipe of described mud is connected with water extracter; Described water extracter is connected by reflux line with settler; Described sewage outlet is connected by pipeline with advanced oxidation device import; Described advanced oxidation device is connected by pipeline with catalyst-assembly, and described catalyst-assembly is connected by pipeline with volume pump by chemicals dosing plant; The mouth of a river is set out on the right side of described advanced oxidation device; Described advanced oxidation device water outlet is connected by pipeline with positive permeator water inlet; Arrange forward osmosis membrane in the middle of described positive permeator, bottom arranges concentrated solution outlet, and described concentrated solution outlet is connected by reflux line with advanced oxidation device, and described positive permeator is connected by pipeline with water-freeing arrangement.On the left of described positive permeator, water-in is set, high density is set above described positive permeator and is just permeating and draw liquid entrance; Described positive permeator is connected by pipeline with water-freeing arrangement.
Principle of work: first waste water enter settling tank under the effect of precipitation agent by sludge settling out, mud passes through the outer discharge pipe of mud to water extracter, water extracter is utilized to remove moisture in mud, the sludge water content removed is back to settling tank again by reflux line, settling tank sewage enters into advanced oxidation device through water outlet and carries out redox reaction, the organism making the difficult degradation in sewage fast and hydroxyl radical free radical generation redox reaction, polymer and larger molecular organics reaction are formed micromolecular compound until generate carbonic acid gas, COD index in quick reduction water thus improve the biodegradable ability of sewage, waste water after advanced oxidation enters in positive permeator and processes, the side of the forward osmosis membrane of waste water in positive permeator is through out-of-date, poor according to the strength of solution of film both sides, draw the driving of liquid in high density under, in waste water, water molecules penetrates into the opposite side of forward osmosis membrane, namely liquid side is drawn, and COD in waste water, heavy metal, the pollutents such as chlorion are trapped, this part waste water be trapped can not directly discharge, advanced oxidation device is back to again through reflux line, proceed oxidation, form a sewage treatment process capable of circulation, sewage after treatment achieves the requirement of zero release, and treating processes is energy-conservation, environmental protection.
The advantage that the utility model has and positively effect are:
1. larger molecular organics is decomposed into small organic molecule by advanced oxidation, and its wastewater biodegradability processed can improve, and chemical oxygen demand (COD) (COD) clearance is high, can meet follow-up water treatment requirement.
2. positive osmosis treatment system is physical filtering system, and by the flow of water concentration of semi-permeable membranes both sides, all the other organism and virus through semi-permeable membranes, and are trapped in the opposite side of film by water molecules, high to the decreasing ratio of pollution substance.
3. the utility model adopts positive osmotic treated device, and saved a large amount of energy consumptions needed for reverse osmosis, the COD of sewage after process meets direct emission request, achieves zero release, and working cost is low, and processing efficiency is high, energy consumption is low, green non-pollution.
