Problems solved by technology
[0002] If the sewage from the printing factory is directly discharged into the urban sewage pipe network and enters the sewage treatment plant without treatment, it will have a great impact on the sewage treatment process, destroy the biochemical treatment system, and pollute the water environment
At the same time, there is a certain phosphorus content in the sewage, which is easy to cause water body phenomena such as blue-green algae

Embodiment 1
[0013] (1) The waste water formed by carton packaging and printing is sent to the filter to filter out solid impurities to obtain the first-stage waste water; among them, the first-stage waste water is 1L;
[0014] (2) After filtering out solid impurities, add 0.2L of 2mol / L hydrochloric acid to the first-stage wastewater for acidification, and further filter out solid impurities to obtain 1.1L of second-stage wastewater;
[0015] (3) Add 0.11L of hydrogen peroxide to the wastewater in the second stage, and treat it at room temperature for 20 minutes to obtain the wastewater in the third stage;
[0016] (4) Add 28g of color remover to the wastewater in the third stage and treat it at room temperature for 30 minutes to obtain 1.1L of wastewater in the fourth stage;
[0017] (5) Add 30g of rare earth slag to the waste water in the fourth stage, and then alkalize it, and add 5g of cesium chloride, and treat it at room temperature for 20 minutes.

The invention relates to a wastewater treatment method, in particular to a carton packing and printing wastewater treatment method. The method comprises the following steps: feeding wastewater formed by carton packing and printing into a filter net, and filtering out solid impurities to obtain first-stage wastewater; after filtering out solid impurities, adding 2mol / L hydrochloric acid to the first-stage wastewater, acidifying, and further filtering out solid impurities to obtain second-stage wastewater; adding hydrogen peroxide to the second-stage wastewater, and carrying out room-temperature treatment for 20 minutes to obtain third-stage wastewater; adding a decoloring agent to the third-stage wastewater, and carrying out room-temperature treatment for 30 minutes to obtain four-stage wastewater; adding rare-earth ore slag to the fourth-stage wastewater, and carrying out alkaline treatment; and adding cesium chloride and carrying out room-temperature treatment for 20 minutes. The carton packing and printing wastewater treatment method has the beneficial effects that through hydrogen peroxide treatment and oxidation, acrylic acid macro-molecules are removed; the nitrogen and phosphorus removal effect can be improved to the maximal extent employing the rare-earth ore slag and cesium chloride under an alkalinizing condition; and wastewater painting can be removed by the decoloring agent, so that the wastewater is relatively clear.
Description
technical field [0001] The invention relates to a wastewater treatment method, in particular to a carton packaging and printing wastewater treatment method. Background technique [0002] If the printing factory sewage is directly discharged into the urban sewage pipe network and enters the sewage treatment plant without treatment, it will have a great impact on the sewage treatment process, destroy the biochemical treatment system, and pollute the water environment. At the same time, there is a certain phosphorus content in sewage, which is likely to cause water body phenomena such as blue-green algae. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to overcome the deficiencies of the prior art and provide a carton packaging and printing wastewater treatment method with good nitrogen and phosphorus removal effect and reduced acrylic macromolecules. [0004] In order to achieve the above goals, ...
