The invention discloses a modification method for semi-dry sintering flue gas desulfurization ash. The modification method comprises steps of grinding and sieving the semi-dry sintering flue gas desulfurization ash, then steeping in deionized water for modification, and steeping in 5-20% oxalic acid for modification. The modification method not only can well modify the desulfurization ash, lower the content of Cl and S in desulfurization ash, and collect and reuse S and Cl in the desulfurization ash so as to alleviate the problem of deficiency of S and Cl to a certain degree; comprehensive utilization of the desulfurization ash in construction materials such as cement and concrete can be realized so as to lower the production cost of the construction materials, and the desulfurization ash can also be used in medical treatment. The modification method is simple, efficient, and low in cost, and has a broad prospect.

The invention discloses a raw material collection structure for preparing urokinase. The raw material collection structure comprises a urinal, the urinal is fixedly installed on a wall through an installation support, a urinating cavity is formed in the urinal, a rotating cavity is positioned below the urinating cavity and communicated with the urinating cavity, a rotating shaft is rotatably mounted in the front end wall and the rear end wall of the rotating cavity and in power connection with a waterproof motor fixedly mounted in the front end wall of the rotating cavity, a rotating plate isfixedly mounted on the rotating shaft, water retaining plates extend upwards and are symmetrically arranged in the front and the rear of the rotating plate, a left through groove and a right through groove are formed in the left end wall and the right end wall of the rotating cavity, a bottom through groove is formed in the bottom wall of the rotating cavity, a sewage draining pipe connected witha sewage draining system is fixedly mounted at the lower end of the bottom through groove, a collection pipe connected with a collection tank is fixedly arranged on the right side of the sewage draining pipe, and a left connecting pipe and a right connecting pipe are fixed outside the left through groove and the right through groove and communicated with the sewage draining pipe and the collection pipe.

The invention relates to a stacked rotary electrostatic generator, belonging to a micro energy system, comprising a power collection assembly, a bearing seat plate, a fixed cylinder, a moving disk assembly, a static disk, a connecting screw assembly, an oil seal bearing and a rotating shaft; the power collection assembly The component is fixed on the rotating shaft, and driven by external force, the rotating shaft and the moving disk assembly fixed on the rotating shaft are driven to rotate synchronously, so that the electret electrode on the moving disk and the working electrode on the static disk are positively aligned. Periodic changes in the area cause periodic changes in the capacitance value, thereby generating electrical signals and outputting them to external circuits. The output electric energy can be applied to the power supply of various wireless sensor nodes or as a real-time monitoring of the flow rate of the environmental fluid. Since the positive and negative electrets are arranged at equal intervals, the charging efficiency on the surface of the moving disk is greatly improved, and the output power of the generator is increased.

The invention relates to an ammonia nitrogen removal device for chinlon chips.The device comprises an anaerobic jar, wherein an overflow pipeline is arranged on the anaerobic jar, and an anaerobic sedimentation tank, an anoxic tank, a contact oxidation secondary sedimentation tank and a three-level peroxidatic reaction ternary sedimentation tank are arranged on the overflow pipeline in sequence.The device has the advantages that production process wastewater in a process wastewater pipeline and sanitary sewage in a sanitary sewer are collected in a centralized mode and homogenized through a water quality regulating reservoir, part of organic matter in wastewater is removed through the anaerobic jar, wastewater is made to pass through the anaerobic sedimentation tank, the anoxic tank, the contact oxidation secondary sedimentation tank and the three-level peroxidatic reaction ternary sedimentation tank in sequence through the overflow pipeline and then is collected through a middle pond, the content of CODcr in wastewater in the middle pond is 85-100 mg / l, the content of NH3-N is smaller than 0.1 mg / l, wastewater discharge standard is met, collection and utilization of wastewater are achieved, and environment pollution is reduced.The invention further discloses an ammonia nitrogen removal process for chinlon chips.
