The application discloses a kind of based on non-complex state manganese oxidation technology's reclaimed water preparation method, it is related to reclaimed water preparation technical field, including following material: phosphate buffer, potassium permanganate, ferrous sulfide, modified chitosan, modified polyaspartic acid, glutamic acid diacetic acid tetrasodium;The application maintains water quality alkaline environment by adding phosphate buffer, greatly inhibits the risk of toxic gas generated by ferrous sulfide hydrolysis, guarantees the safety of preparation process;The modified chitosan added, by electric neutralization and adsorption bridging, small precipitate is quickly flocculated into sedimentable alum flower, realizes mud-water separation;By adding modified polyaspartic acid, can prevent the scale formed by precipitation in irrigation pipeline or equipment, and glutamic acid diacetic acid tetrasodium synergistic effect, jointly ensure the chemical stability of reclaimed water in storage and conveying process, protect irrigation system, water quality long-term stability.

This invention relates to a method and application for the recovery of salt mud, belonging to the field of chemical process technology. The invention utilizes a chemical reaction between sodium sulfate in mineral brine and calcium chloride in the wastewater discharged from a soda ash plant. The salt mud produced from the refined mineral brine is then mixed with the above reaction solution. After sedimentation and filtration, a mixture of sodium chloride, gypsum, and salt mud is generated. The obtained sodium chloride can be used to produce soda ash, while the gypsum and salt mud mixture can be used as a building material. The gypsum and salt mud mixture obtained by the method of this invention has stable properties and can be directly sold as a semi-finished product. The method of this invention employs multiple processing steps, reducing equipment and pipeline blockage during the recovery process and minimizing corrosion of equipment by raw materials and intermediate products. This significantly reduces operating costs, facilitates extended production cycles, and meets the current high demand in the soda ash market, resulting in high economic benefits.

This invention provides a high-efficiency and energy-saving pump station system, belonging to the field of pump station technology. It includes a pump station outer casing, pump station components, and a control cabinet. The outer casing is modularly designed, and the pump station components and control cabinet are installed in different modular casings at the factory. The system is then debugged and tested according to different pump station parameters to measure output water volume and power data. The modular casings are transported to the destination by truck and then assembled. Users can remotely view the working status data of the pump station components through a client application. This invention, by modularizing the pump station outer casing, makes the installation and transportation process more efficient. Traditionally, building a pump station takes approximately 45 days, but this invention allows for installation and construction to be completed in just two days, significantly improving efficiency. The standardized pump house and modular components enable rapid installation and commissioning.
