FIG. 2 is a flow chart of the industrial wastewater purification method of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1-2, the industrial wastewater purification method provided by the present invention comprises the following steps:
the first step, pass through the filter screen with sewage and filter, discharge to the tank 1 after the great debris of filtering aquatic, great debris are some waste materials in the industrial production process generally, can retrieve and recycle, are favorable to practicing thrift the cost, the environmental protection.
And secondly, atomizing the sewage by adopting an ultrasonic atomization mode, depositing impurities insoluble in water in the sewage at the bottom of the water storage tank 1, and allowing the impurities soluble in water to enter a condensation bin along with water mist and then flow into a regulating tank.
Supersonic generator sets up in tank 1 middle part, and supersonic generator atomizes the water in with tank 1, and the fog condenses into the water droplet after getting into to condense in the storehouse 2, and silt and the large granule impurity of tank 1 bottom deposit can regularly carry out manual cleaning, purification.
And thirdly, adding a regulator into the regulating tank 3, stirring and mixing to ensure that the pH value of the water body is 7.0-8.0, filtering the water body, and introducing the filtered water body into the adsorption tower 4.
The regulator added into the regulating tank 3 is soda ash or sulfuric acid, and the soda ash or the sulfuric acid can be added to regulate the pH value of the water body so as to be suitable for the survival of microorganisms on one hand and can precipitate calcium ions, magnesium ions and copper ions in the water on the other hand.
Fourthly, the water body is subjected to adsorption reaction in the adsorption tower 4 for about 5 to 8 minutes, and then the purified water is discharged.
Be equipped with the active carbon cage in the adsorption tower 4, the active carbon cage is a polyhedron, stably fixes in the adsorption tower, and the inside vertically and horizontally staggered of active carbon cage is provided with the active carbon skeleton, and the active carbon skeleton increases adsorption area on the one hand, and on the other hand is used for hanging and establishes the microbial film, and the inside microbial film that is equipped with is all hung with the surface to the active carbon cage.
