[0019] Example 1: Disposal of waste quilts
[0020] like figure 1 As shown, the method successively undergoes crushing, cleaning, primary drying, disinfection, and secondary drying of cotton solid waste, and then weaves cotton cloth or cotton wool blocks, and then adds bio-glue to the prepared cotton wool blocks and completely mixes with the constructed wetland matrix. Mixing, preparing compressed wetland matrix blocks by compression, and finally wrapping the compressed wetland matrix blocks with the prepared single-layer cotton cloth, so as to prepare finished matrix blocks.
[0021] The crushed length of cotton solid waste should be less than 30mm, and it should be in the form of floc; after washing, the ash content of the crushed cotton flocs should be less than 0.3%; Moisture content is less than 10%.
[0022] Ultraviolet disinfection is used for disinfection, and the intensity of ultraviolet rays irradiated by ultraviolet lamps shall not be lower than 70uW / cm 2 , the i...

Abstract
The invention discloses a cotton solidwaste treatment and artificial wetland utilization method. The technological process of the method includes crushing cotton solid waste, cleaning, primary drying, disinfection, secondary drying, weaving cotton cloth or cotton wool blocks, The cotton wool block is mixed with the constructed wetland matrix after adding biological glue to prepare the constructed wetland matrix compressed block, and the constructed wetland matrix block is wrapped with cotton cloth to prepare the finished matrix block. This method effectively applies cotton solid waste to constructed wetlands, and this method can realize the complete resource utilization of cotton solid waste in domestic waste, and at the same time effectively promote the effective utilization of solid waste and the improvement of the technical level of constructed wetlands. improve. The method is simple, low in operation cost, strong in operability, and has high promotion and application value.
Description
technical field [0001] The invention relates to the technical field of waste utilization in environmental protectionengineering, in particular to a cotton solid waste treatment method and a constructed wetland utilization method. Background technique [0002] Because cotton clothes are warm in winter and cool in summer, they are favored by consumers. In recent years, my country has produced a large amount of cotton waste, and improper treatment has seriously polluted the environment. Because cotton solid waste contains pollutants, it is an effective To utilize cotton waste, its unfavorable factors should be overcome. [0003] In addition to the renovation of waste cotton, there is currently no effective method for the treatment and utilization of cotton solid waste. Therefore, it is of great significance to develop cotton solid waste treatment and utilization technology to realize the complete resource utilization of cotton solid waste. At present, the main authorized or p...
