This invention relates to the field of aquaculture water treatment technology, and discloses a multi-stage purification and filtration system and filter dam device for fish ponds. The system includes a multi-stage flow-guiding filter dam, a piezoelectric-biocoupled reactor, and an adaptive resonant control system. The piezoelectric-biocoupled reactor is filled with piezoelectric composite biological filler. A micro-electric field is generated by ultrasonic excitation, which works synergistically with the biofilm to degrade pollutants. The adaptive resonant control system monitors the acoustic impedance value within the piezoelectric-biocoupled reactor in real time and adaptively adjusts the ultrasonic output parameters based on deviation using a differential algorithm, achieving dynamic control and in-situ renewal of the biofilm thickness. The system also includes anoxic autotrophic denitrification and reoxygenation reflux devices at the back end. Through the microscopic coupling of piezoelectric catalysis and biodegradation, and intelligent closed-loop feedback control, the system achieves simultaneous and efficient removal of recalcitrant organic matter and ammonia nitrogen, ensuring the high activity and long-term stable operation of the purification system.

The invention relates to the technical field of waste liquid treatment, in particular to a self-adaptive pH amphoteric polymer-calcium salt compounded bentonite slurry rapid sedimentation treatment method. According to the method, a calcium salt working solution, a buffer working solution, an amphoteric polymer working solution and a functionalized calcium carbonate micro-powder dispersion solution are added in stages, and the stirring speed and time are accurately controlled, so that rapid sedimentation of the slurry is realized. The amphoteric polymer is formed by copolymerizing a plurality of monomers and has wide pH adaptability; the functionalized calcium carbonate micro powder is used as a weighting carrier to enhance the floc density. The method solves the problems of slow sedimentation, high supernatant turbidity and poor adaptability to water quality fluctuation in the traditional method, has the advantages of high sedimentation speed and high supernatant clarity, can be directly reused, and is suitable for bentonite slurry treatment in the fields of electric power engineering and the like.

The invention provides a traditional Chinese medicine composition for treating diabetic nephropathy as well as a preparation method and application thereof, and belongs to the technical field of biological medicines. The traditional Chinese medicine composition is prepared from the following raw materials in parts by weight: 40 to 50 parts of rhizoma coptidis, 40 to 50 parts of radix astragali seu hedysari, 25 to 35 parts of radix paeoniae rubra, 25 to 35 parts of radix salviae miltiorrhizae, 3 to 9 parts of scalded leech, 1 to 5 parts of wine-treated radix et rhizoma rhei, 110 to 130 parts of fried fructus rosae laevigatae, 110 to 130 parts of fried semen euryales, 25 to 35 parts of rhizoma anemarrhenae and 25 to 35 parts of radix trichosanthis. Animal experiments prove that the traditional Chinese medicine composition reduces fasting blood-glucose and urine trace protein content of rats with diabetic nephropathy. Clinical cases prove that the traditional Chinese medicine composition improves various symptoms of the diabetic nephropathy and has a remarkable curative effect on treating the diabetic nephropathy.

The application discloses a kind of high top pressure and the regulation and control method of fixed pressure difference of blast furnace, comprising the following operating steps: S1: before implementing high top pressure, confirm that blast furnace system is stable and proceeds in order;Blast furnace fan air release line is adjusted to 30kpa~40kpa;S2: the blast furnace belongs to the blast furnace of control edge open center operation, after improving top pressure, the edge coke ring of blast furnace coke distribution reduces a ring, after adjustment, if the furnace condition reaction still tends to edge airflow development, then the ore coke angle is simultaneously increased 0.2°~0.3°;The blast furnace belongs to the blast furnace of balance two airflow operations, after improving top pressure, the edge coke ring of blast furnace coke distribution reduces a ring;After adjustment, if the furnace condition reaction still tends to edge airflow development, then the edge ore ring is increased a ring, center coke ring number: increase 0.2~0.5 rings.This method can smoothly transition to high top pressure production state, strengthen smelting process, improve blast furnace index.
