A process for recovering the waste acid in producing titanium oxide powder by the sulfuric acid method features use of gas-liquid separation type non-volatile solution concentrating apparatus. It includes such steps as depositing the waste acid to receiver solid Ti, pre-concentrating at 50-60 deg.C until acid concentration is 40-50%, filtering, and concentrating at 65-75 deg.C until its concentration reaches more than 70%.

The object of the present invention is to provide a cassette paint machine with a painting unit for spraying paint, a simple, light and cheap cartridge for storing paint therein and for supplying paint to this painting unit A cassette is removably mounted to the paint coater. In the painting machine (11), a painting device having a rotary spray head (14) etc. is arranged at the front part of the casing (12), and a cartridge (21) in which paint is stored is detachably mounted to the casing ( 12) back part. The paint in the cartridge (21) is supplied to the rotary spray head (14) by pressurizing the cartridge (21) with a liquid, and the housing (12) and the cartridge (21) form a chamber for storing the liquid Pressurize the solvent storage chamber (18b).

The invention relates to a system for reutilizing bromomethane by vacuum heating, which comprises a heating cavity, a closed fumigation facility, a valve, a vacuum pump and pipelines, wherein a plurality of carbon material packed columns are arranged in the heating cavity, and the structure of each carbon material packed column is a cylinder with a cavity; the carbon material packed columns are connected in parallel and communicated; the upper communicating pipeline is led out of the upper part of the heating cavity and then connected with the vacuum pump, passes through the vacuum pump and is further connected to an upper pipeline interface of the closed fumigation facility; the lower communicating pipeline is led out of the lower part of the heating cavity and then connected with a circulating fan, passes through the circulating fan and is further connected to a lower pipeline interface of the closed fumigation facility; the carbon material packed columns adopt the vertical placement, thereby effectively solving the difficult problems of non-uniform distribution of activated carbon or carbon fibers, and difficulty in replacement of the activated carbon or the carbon fibers; the vacuum pump is adopted for vacuum-pumping of the carbon material packed columns, and then the bromomethane adsorbed in carbon material is heated for desorption, thereby improving the desorption effectand reducing the heating desorption temperature; and the bromomethane which is desorbed by vacuum heating can be directly discharged to the fumigation facility with goods to be fumigated, thereby reducing the reutilizing cost of the bromomethane.

The invention discloses a process for recycling electroplating wastewater. The process comprises the following steps: (1) carrying out advanced-treatment pretreatment on the electroplating wastewater; (2) carrying out advanced-treatment aftertreatment on discharge water; (3) enabling treated wastewater to flow through filter paper so as to filter the treated wastewater; (4) pumping the wastewater into reverse-osmosis equipment; (5) carrying out detecting. By adopting the wastewater recycling process disclosed by the invention, requirements of the reverse-osmosis equipment on influent water quality can be met, the water quality of recycled water is stable, normal operation for the reverse-osmosis equipment can be ensured, the reverse-osmosis equipment can normally work for 10 months and even longer than 1 year, and meanwhile, the wastewater of a high-pressure side can be discharged after reaching standard.

The invention discloses an extraction method for ferulic acid in rice bran meal. According to the method, cross-linking fixation is carried out on biomagnetic nanometer materials such as magnetosome and feruloyl esterase by adopting transglutaminase so as to obtain immobilized feruloyl esterase, then ferulic acid ester in rice bran meal after rice bran oil is extracted is pretreated by adopting the immobilized feruloyl esterase, extraction is carried out by using isopropyl alcohol after pretreatment, after solid-liquid separation of the extracting solution, then microfiltration and nanofiltration two-stage decontamination and low-temperature vacuum concentration are adopted, and activated carbon decoloration and recrystallization carried out on concentrated solution, so that a ferulic acid product with the purity of more than 98% is obtained. Natural ferulic acid is extracted from rice bran meal by adopting the immobilized feruloyl esterase, so that the problems of environmental pollution, low safety and high industrialized production cost existing in the prior art are overcome, and the extraction method has preferable application prospects.
