Technical field
The present invention relates to technical field of waste water processing, more particularly relate to a kind of method and device that is used for Phenol-Containing Wastewater Treatment.
Background technology
Along with the raising of China's economic level, ceramic industry is current to be obtained flourishly, but has also brought a large amount of reluctant waste water simultaneously, and as the Foshan City as the township of pottery, the sewage quantity of generation every day is more than 6000 tons, and the pollution of environment also is on the rise.The main energy sources that present ceramic enterprise uses is changeed gas as coal, therefore, contains reluctant phenolic wastewater in the ceramic wastewater, the concentration height of phenol wherein, and toxicity is big, and is also special big to the pollution of environment, so it is extremely urgent to handle ceramic phenol wastewater.
At present, the general employing of the method for handling this class ceramic phenol wastewater carried out flocculation treatment by the flocculation agent for preparing high strong oxidizing property, also can adopt the biomembrance process Phenol-Containing Wastewater Treatment, can also adopt the direct oxidation of FENTON reagent to handle, or handle waste water with the catalytic air oxidation method.Also develop in the eighties in last century and to utilize special the handle organic waste water of water under supercritical state, this several method, because certain condition restriction is arranged, or need the on-site preparation flocculation agent, or owing to pH value, influence such as temperature is bigger, therefore be difficult to stably handle ceramic phenol wastewater, in addition, also be subjected to the influence of cost, equipment etc., limited their extensively promoting the use of at home.
Summary of the invention
Purpose of the present invention is exactly that a kind of not only cost that provides for the deficiency that solves prior art is low, technology is simple, and the treatment process of the high ceramic phenol wastewater of clearance.
Another object of the present invention provides that a kind of not only cost is low, technology is simple, and the treatment unit of the high ceramic phenol wastewater of clearance.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of treatment process of ceramic phenol wastewater is characterized in that it comprises the steps:
A, preliminary treatment waste water, ceramic phenol wastewater at first enter absorption and the filtration that the cinder jar carries out waste water, enter dosing conditioned reaction pond again, add the reaction medication, regulate to make waste water and the oil removing of medicament uniform mixing;
B, will send to successively in iron charcoal first order reaction pond and the iron charcoal second order reaction pond through the waste water of preliminary treatment and carry out the aeration micro-electrolysis reaction, stay for some time, and between two reaction tanks, make pump around circuit simultaneously and handle;
C, the waste water that the b process is handled through step of reaction are sent to and are further removed phenol and COD pollutent in the biochemistry pool;
D, advanced treatment, discharge can reach the water of country and local sewage drainage standard.
As further specifying of such scheme, in aforesaid method step b process, adopt even stringing mode to handle at two reaction tank intercropping cyclic aeration micro-electrolysis reactions, the time of processing is 0.8～2 hour.
In aforesaid method step b process, also need regularly to add waste iron filing to reaction tank.
A kind of treatment unit of ceramic phenol wastewater, it is characterized in that, it comprises cinder jar, the dosing conditioned reaction pond that connects successively, two reaction tanks, biochemistry pool and the advanced treatment apparatus that is provided with reflux, the inside in each pond has pipeline to distribute and is interconnected by this pipeline, and this pipeline is a pvc pipe.
Described cinder jar is a cylindrical shell, is provided with pipeline in the cylindrical shell.
Upper end, described dosing conditioned reaction pond is provided with feed-pipe and feed system, and side, dosing conditioned reaction pond is provided with chemical feed pipe, slag-drip opening, and lower end, dosing conditioned reaction pond is provided with rising pipe.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: the present invention adopts the little electrolysis advanced treatment of aeration, can effectively remove phenol and COD in the waste water, and the biodegradability of water outlet has simultaneously had and increases substantially; Cinder adopts waste from a factory, burning disposal once more after the use, and non-secondary pollution has also reached the meaning of " treatment of wastes with processes of wastes against one another " simultaneously; Aeration micro-electrolysis reaction district feeds intake convenient and simple, and the processing efficiency height, only need regularly add a certain amount of waste iron filing, processing cost is low, and has reached the purpose that refuse utilizes once more, value of environmental protection height, and have good treatment effect, current consumption is few, and Inlet and outlet water is convenient.

Embodiment
The treatment process of ceramic phenol wastewater of the present invention, in the treating processes of handling ceramic phenol wastewater, its reaction process can be divided into four-stage:
Fs: mainly be adsorption process, ceramic phenol wastewater at first enters absorption and the filtration that the cinder jar carries out waste water, and main in the cinder jar have the cinder adsorption can remove the phenol of the phenolic wastewater of part because be; The main effect that this stage plays is to handle the bigger suspended matter of particle and the phenolic wastewater of absorbed portion concentration, enter dosing conditioned reaction pond once more, add the reaction medication, regulate making waste water and medicament uniform mixing, further oil removing when handling waste water to contain phenol;
Subordinate phase: this process is a step of reaction of its dominant position, to send to successively in iron charcoal first order reaction pond and the iron charcoal second order reaction pond through the waste water of preliminary treatment and carry out the aeration micro-electrolysis reaction, in this process iron charcoal first order reaction pond and iron charcoal second order reaction pond all is the aeration micro-electrolysis device, waste water must stop 0.8～2 hour in these two reaction tanks, also can carry out reflow treatment several times simultaneously, improving the processing efficiency of waste water, the clearance of its waste water of reaction by this stage can reach higher level;
Phase III: waste water enters biochemistry pool through after the subordinate phase, and this process mainly is the biochemical degradation process, is further to remove pollutents such as phenol and COD again on original basis, and the requirement of the water outlet of this moment can reach the processing efficiency of 80%-85%;
Quadravalence section: the treatment stage that this process being last, be exactly an advanced treatment apparatus, require water outlet can reach country and local sewage drainage standard.
