Abstract: A coupled medium-low temperature flue gas processing apparatus for fly ash washing includes a reactor and scraping rings. In the present disclosure, arranging the scraping rings can scrape the fly ash adhered to the inside of the reactor and bring the scraped fly ash into a mixing liquor to prevent the fly ash from adhering and accumulating, which not only results in the decrease of the fly ash content participating in the reaction, and the difficulty to react with water completely, but also the fly ash adhered to the inside of the reactor will form a thick object after mixing with the water, once the thick object is dried, the adhesive capacity thereof is greatly enhanced.

Abstract: A processing apparatus for removing dioxin in fly ash from domestic waste incineration by using a ball mill includes a grinder as well as a feeding body and a discharging body that are separately arranged at both ends of the grinder. In the present disclosure, an induction coil is electrified by arranging a heating body to generate an alternating magnetic field such that eddies generate on an inner wall of a grinding cylinder in the induction coil, the grinding cylinder is heated by the energy of these eddies, making a grinding ball thermally desorb and decompose a harmful component, that is, dioxin in the fly ash through a high temperature when grinding the fly ash from the domestic waste incineration since a temperature in the grinding cylinder reaches 300-500° C. during grinding.

Abstract: A biochemical sludge and physicochemical sludge separate sampling device for identifying attributes of sludge, includes a sludge extraction assembly, and a biochemical reaction tank and a physicochemical reaction tank which are respectively connected to the sludge extraction assembly through connection pipelines. The sludge extraction assembly includes an outer shell, a porous plate clamped to an inner bottom of the outer shell, and a sampling dish. A drain pipe is arranged at a lower end of the outer shell. The sampling dish is provided with a biochemical sludge cavity and a physicochemical sludge cavity. Filter cloth is arranged at inner bottoms of the biochemical sludge cavity and the physicochemical sludge cavity. Electric extrusion stems are arranged at an inner top of the outer shell; and the electric extrusion stems are provided with extrusion plug plates.

Abstract: The present disclosure provides a session binding relationship processing method and apparatus, an electronic device, and a readable medium. The method includes: in a case where a preset first condition for user group migration is met, determining a first user group, with the first user group including at least two session users; and sending a management create request message carrying information of the first user group and information of a current Policy Control Function entity to a Binding Support Function entity, so as to allow the Binding Support Function entity to establish a first binding relationship between the information of the user group and the information of the Policy Control Function entity according to the information of the first user group and the information of the current Policy Control Function entity.

Abstract: A system for a sandy soil landfill solid waste polluted river channel, includes a ground water interception and diversion system and a river channel ecological remediation system. The ground water interception and diversion system includes a water intake well arranged upstream of ground water in a landfill area, a buffer pool communicated with the water intake well, and a wastewater treatment system communicated with the buffer pool. The water intake well, the buffer pool, and the wastewater treatment system are communicated through a wastewater pipe. An electric wastewater valve and a variable frequency water pump are arranged on the wastewater pipe in sequence. The river channel ecological remediation system includes an impermeable layer arranged at a bottom of a river channel and ecological bank protections arranged on both sides of a river channel slope.

Abstract: The present rivet invention has a main body comprising a first end and a second end opposite to the first end, wherein the main body further comprises a lateral wall disposed at the second end and circumferentially extending around the main body; and a core part disposed at the second end of the main body and contained inside the lateral wall of the main body, wherein the core part has an end surface for pressing against at least an end surface of one of the work pieces when the rivet is being operated to rivet the work pieces, to allow materials of the work pieces flow outwardly of the core part. An accommodation space is formed between the core part and the lateral wall to receive materials of the work pieces flowing into the space and deform outwardly at least a portion of the lateral wall of the main body.

Abstract: The invention provides new heterocyclic compounds having the general formula (IA) wherein A, L, X, Y, m, n, R1 and R2 are as described herein, compositions including the compounds, processes of manufacturing the compounds and methods of using the compounds.

Abstract: The present application pertains to a fluid pressure operated press-riveting device, comprising: a cylinder having a distal end, a proximal end and a sidewall extending axially between the distal end and the proximal end, wherein the distal end has an opening section; a first piston in the cylinder, which defines a first inner chamber with the proximal end and has a press-riveting rod extending towards the distal end and aligned with the opening section; a second piston in the cylinder, which defines a second inner chamber with the distal end, and has a sleeve section extending to the distal end, which at least extends to and closes the opening section and can accommodate the press-riveting rod; a fluid pump system, which is respectively connected with the first inner chamber and the second inner chamber to supply fluid thereto or suck fluid back therefrom, so that the first piston and the second piston move axially along the cylinder, when the second piston moves to the distal end, the sleeve section moves t
