Description
Technical Field
The invention relates to the field of water treatment, in particular to a treatment process of oily heavy metal industrial wastewater.
Background
In the production fields of machining, mining, metal smelting, electroplating and the like, a large amount of oily heavy metal wastewater can be generated, heavy metals in the wastewater have toxicity, if heavy metal pollutants are directly discharged, the heavy metal pollutants can be remained in the environments such as atmosphere, water, sediment, soil and the like, the land polluted by the heavy metals in China at present reaches over ten million square hectares, under the influence of the heavy metal pollution of the soil, the health problems caused by the heavy metal pollution are frequently reported in recent years, no alarm clock is required to be knocked, the influence of the heavy metals on the soil at present is warned to be continuously expanded, and therefore the work of preventing and treating the heavy metal wastewater is very important.
The treatment method of heavy metal containing oil in the existent technology mainly includes chemical treatment and physical treatment and chemical and physical mixing treatment, at present, the treatment of heavy metal containing oil waste water adopts the air-float machine which is a comprehensive chemical and physical method to treat, in the air-float machine a flocculating agent and a coagulating agent are added, the flocculating agent is used to make suspended matter and grease flocculate mutually, the flocculating agent is used to make the small granules formed by flocculating agent adsorb and connect mutually so as to form large flocculate body which can be quickly separated from water, then the gas-dissolving system of air-float machine can release small bubbles in the combining zone of air-float machine, these small bubbles are attached on the flocculate body to make the flocculate body float upwards, then the floated scum is cleaned, the coagulating agent and flocculating agent can be used to make the oil and heavy metal in the heavy metal containing oil waste water form flocculate body, and the flocculate body can be floated upwards floated by means of bubbles, then the scum of the floating floc is scraped and cleaned by the scraper to realize the purification effect of the oil-containing heavy metal, but in the existing air floating machine, the scum is cleaned by the rolling scraper, the method needs to accurately control the scraping frequency and the scraping speed of the scraper, because the scraping frequency of the scraper is not adjusted frequently, the forming speed of the scum can be changed continuously according to the content of fine particles in the oil-containing heavy metal waste liquid, if the scraping frequency is lower than the forming speed of the scum, more scum thickness can be thickened, the thickened scum has less water content, the scum with reduced water content is scraped into a sludge tank, the scum is transmitted into a scum treatment device through a transmission device to treat the scum, and the scum needs to be contacted with the scum which does not flow out when the scum is scraped by the scraper, at the moment, the scraper can crack the tiny bubbles on the floc, the floc loses the buoyancy of bubble and can continue to sink to the aquatic, but if the moisture content of dross reduces the back comparatively dry dross can cause the jam to transmission device, if scrape the frequency too fast, this just will require the removal rate of scraper blade to accelerate, and scraper blade removal rate will strengthen the effort to the dross too fast, and this is just destroyed the dross more easily, causes waste water purifying effect to reduce.
Therefore, in order to prevent the scum from being damaged by contact when the scum is cleaned and prevent floc from settling in water to influence the water purification effect, the treatment process of the industrial wastewater containing the oil and the heavy metal is provided.
