Problems solved by technology
Although industrial wastewater has been filtered, some pollutants will still remain in the wastewater, which will inevitably pollute the natural environment
[0003] It is also a waste of resources to discharge the filtered sewage directly. It is feasible to use the filtered industrial sewage for steam production in the steam industry. Currently, in the steam production industry, there is still no complete set of industrial sewage recycling for steam production. Methods

Embodiment Construction
[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0017] As shown in the figure, a method of utilizing industrial waste water to produce steam is characterized in that: comprising the following steps:
[0018] Preliminary treatment: collect industrial wastewater generated during production, remove heavy metals, dissolved organic matter, and radioactive substances in industrial wastewater through physical and chemical treatment and biochemical treatment; inject ozone into wastewater after physical and chemical treatment and biochemical treatment to remove peculiar smell in wastewater and decolorization;
[0019] Primary filtration treatment: The industrial wastewater that has been preliminarily treated is filtered through a sand filter, a precision filter and an ultrafiltration membrane in sequence to remove larger particle pollutants and floating objects in the industrial wastewater;

The invention discloses a method for producing steam by utilizing industrial waste water. The method is characterized by comprising the following steps: collecting the industrial waste water generated in production for physicochemical treatment and biochemical treatment, pouring ozone into the waste water subjected to physicochemical treatment and biochemical treatment for removing peculiar smell of the waste water and decoloring, carrying out primary filtering on the initially treated industrial waste water sequentially through a sand filter pool, an ultrafilter and an ultrafiltration membrane for removing large particulate pollutants and flotages in the industrial waste water, carrying out secondary filtering on the industrial waste water subjected to primary filtering treatment sequentially through a cartridge filter and a reverse osmosis membrane for removing small particulate pollutants and flotages in the industrial waste water, introducing the industrial waste water after secondary filtering treatment to the reverse osmosis membrane and ultrafiltration water production so that the degree of purity of the industrial waste water meets the requirements of steam production, and transmitting the filtered and purified industrial waste water to a boiler for steam production. By utilizing the method, the structure is compact, waste of resources is reduced, energy is saved, and environment is protected.
Description
technical field [0001] The invention relates to the field of steam production, in particular to a method for producing steam by utilizing industrial waste water. Background technique [0002] Industrial wastewater (industrial wastewater) includes production wastewater and production sewage, which refers to wastewater and waste liquid generated during industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water. This kind of pollutant is produced in large quantities in industrial production, and the general treatment method is to discharge the pollutant directly into rivers and lakes after being filtered. Although industrial wastewater has been filtered, some pollutants will still remain in the wastewater, which will inevitably pollute the natural environment. [0003] It is also a waste of resources to discharge the filtered sewage directly. It is fea...
