Abstract: An inner frame of a door or a window is disclosed. The inner frame is disposed at an inner side of a window sash, and is connected between a jamb of the door or the window sash and a door frame or a window frame. The inner frame includes a fixing portion for fixing to the jamb, a water baffle, and a connecting portion for connecting with the door frame or the window frame. One side of the fixing portion is fixed to the jamb, the water baffle is integrally disposed on the other side of the fixing portion opposite to the one side, and the connecting portion is integrally disposed on a side of the water baffle facing away from the fixing portion and is connected to the door frame or the window frame.

Abstract: The invention discloses an infinite-arbitrary-length bamboo chip integrated material. The bamboo chip integrated material is formed by a plurality of lengthened bamboo chips which are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are butted; sharp teeth and grooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matched to form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and each bamboo chip unit has a thickness of 4-12 mm and a width of 15-50 mm. The invention further provides a manufacturing method of the bamboo chip integrated material, comprising the steps of preparation of the bamboo chip units, meshing and butting, hot pressing and gluing and the like.

Abstract: Taught is a method for removing ammonia nitrogen from an ammonia-containing solution via atomization, comprising a) adjusting the pH of the ammonia-containing solution to above 10 by adding a base; b) after mixing, atomizing the ammonia-containing solution to produce an ammonia-containing mist so as to increase the gas-liquid interface and allow ammonia to transfer from the ammonia-containing mist to an ambient gas yielding a clean mist; and c) re-aggregating said clean mist. The method is applicable for treatment of liquids containing high, medium and low ammonia nitrogen concentration.
