Inventor: ZHANG HAIFENG
IPC: C02F3/16
Filed: 2021-12-16
Granted: 2022-05-23
Abstract: A cathode-loaded self-forming dynamic membrane bio-reactor consists of three parts: biological treatment system, cathode-loaded system and automatic control system. The biological treatment system mainly consists of water inlet pump, perforated aeration pipe, aeration pump, dynamic membrane module, etc. The cathode load system consists of DC regulated power supply, electrode plate and cathode load interface. The automatic control system consists of liquid level controller and time relay. When the cathode system is running, the electrode plate will release metal ions, which can strengthen the biological flocculation behavior of activated sludge. Hydrogen evolution reaction will occur in the cathode-loaded dynamic membrane, and the tiny bubbles will increase the compressibility of the dynamic membrane, and the bubbles will be displaced and broken by the compression of the mud cake layer, which will loosen the dynamic membrane and prolong the stable operation period of the dynamic membrane.

Abstract: The invention relates to a method and a device for continuous cold mixing of road surfacing material. Aggregate is supplied to a hopper (1), is weighed on a belt weigher (3) and conveyed to a screen (6) for separation into different size ranges. The different portions are then supplied to a compulsory mixer (7), in which they are cold mixed with bitumen emulsion. According to the invention, the aggregate is continuously separated into at least three portions which are supplied to the compulsory mixer (7) via different inlets (9a, 9b). The portion having the greatest particle size is first mixed with an excess of bitumen emulsion for this portion. Each aggregate portion of successively decreasing particle size is then separately mixed with an excess of bitumen emulsion for each portion, while they are successively mixed with the already bitumen-mixed aggregate portion/s having a greater particle size. Last, the aggregate portion/s having the smallest particle size/s are mixed with the already bitumen-mixed aggregate portions without additional bitumen emulsion being supplied separately to this or these aggregate portions.

Matrix metalloproteinases (MMP) are a family of zinc-containing calcium dependent proteinases, including stromelysins, collagenases, and gelatinases. These MMP enzymes are capable of degrading the proteinaceous components of connective tissue and appear to be involved in tissue remodeling, i.e., wound healing and connective tissue turnover. Unexpectedly, the mercaptoalcohols with the S-configuration at the hydroxyl-bearing carbon have been found to be at least 4 times more potent than the analogous (R)-alcohols both in vitro and in vivo in inhibiting the MMP enzyme..
