The invention discloses a method for preparing polymer modified phase-stable ammonium nitrate. The method comprises the steps of synthesizing an organic polymer from styrene sodium sulfonate, acrylic ester, dimethyl diallyl ammonium chloride and butene diacid sodium by use of monomers, dissolving an organic monomer in water, stirring and heating the water, dripping initiator, preserving heat, heating, preserving heat, adding the synthetic organic polymer to a ammonium nitrate aqueous solution, heating the solution for dissolution, stirring the solution fast, naturally cooling the solution forcrystallization, drying crystals at a temperature between 50 and 80 DEG C and obtaining the polymer modified phase-stable ammonium nitrate. As the method adds the organic polymer to ammonium nitrate,and as the polymer is low in air permeability and excellent in film-forming property, a film is great in toughness and elasticity, high in strength, capable of bearing volume expansion caused by crystal ...

The invention relates to a biological nitrogen and phosphorus removal process of sewage and a matched device of a V-shaped biological aerated filter pool, belonging to the field of sewage treatment. The biological nitrogen and phosphorus removal process of sewage of the V-shaped biological aerated filter pool is characterized in that sewage enters a biological filter medium layer from the upper part of the V-shaped biological aerated filter pool and is subjected to nitratlon reaction and denitrification reaction in the biological filter medium layer, and the sewage is sequentially discharged from the bottom of the biological aerated filter pool through a fine filtering layer, a support layer and a filter head. The biological nitrogen and phosphorus removal process of sewage of the V-shaped biological aerated filter pool gets rid of the main flow type of upward flow light biological aerated filter pool, adopts a downward flow type, and is additionally provided with the fine filtering layer ...

The invention belongs to the technical field of water treatment and in particular relates to a method for performing advanced treatment and reuse on oil-refining sewage and a matched device. The advanced treatment and reuse method comprises the following steps of: performing preoxidation flocculation filtering on effluent (pressure flow) from a sewage treatment field by using a multi-medium filter; allowing the filtered water to enter an ozone-biological active carbon unit; decomposing, degrading, and removing pollutants such as organic matters and the like by utilizing a chemical oxidation reaction principle and a biological reaction mechanism; allowing the obtained water to enter a UF-RO desalination system and a conventional anion-cation exchange bed system successively and then reusing continuously. After being treated by the method, the effluent meets various indexes of reuse water; treatment cost of acid and alkaline wastewater is reduced; service life of resin is prolonged; and advantages ...
