The present invention provides a manufacturing method of copolyester for low acetaldehyde content of PET bottles. The polyethylene terephthalate (PET) polymer is added with an appropriate modifier in order to decrease the production of acetaldehyde caused by pyrolysis side reaction during the blow molding process of PET bottles. The modifier comprises stabilizer and primary antioxidant, wherein the stabilizer is an inorganic phosphorous compound with an addition quantity of 0.003~0.5 weight % based on the weight of the total copolyester copolymer and the primary antioxidant is a hindered phenolic antioxidant containing Ca+2 with an addition quantity of 0.005~5.0 weight % based on the weight of the total copolyester copolymer. The present invention owns an improving effect of decreasing the production of side product-acetaldehyde at least 30% than those without the addition of said modifier.

The invention relates to a method for treating glyphosate waste water by using calcium hypochlorite waste water. The method comprises the following steps: performing redox reaction on calcium hypochlorite waste water and glyphosate waste water, converting glyphosate and phosphite radical in the glyphosate waste water into inorganic phosphorus compounds, and combining with calcium ions in the treating liquid to form precipitate, so that the content and COD value of total phosphorus in a permeate can be reduced, and the purpose of treating glyphosate waste water can be achieved. Compared with the traditional treatment method, the method is good in effect and low in cost, the adopted treating liquid is waste water, so that the method is economic and environmentally friendly, capable of achieving the purposes of treating wastes with wastes and realizing comprehensive treatment, as well as is simple to operate, mild in conditions, and capable of performing large-scale treatment, and the treated waste water is in accord with the national emission standard and can be directly emitted.
