| 20120125860 | WASTE SLUDGE DEWATERING - Technologies are generally described for processes, compositions and systems for waste sludge dewatering. In an example, the process may include receiving a waste sludge including a water component and an initial content of suspended particulates. The process may include treating the waste sludge with a combination of flocculant produced by | 05-24-2012 |
| 20120045013 | METHOD FOR REAL-TIME ONLINE CONTROL OF HYBRID NONLINEAR SYSTEM - The present invention provides a method for real-time online control of hybrid nonlinear system, characterized in that, it comprises the following steps: a. the current observational state of plant in the network is transmitted to first controller, where said first controller is used to provide real-time online control for plant, which guarantees the asymptotic stability of the controlled plant in the network; b. Said first controller obtains the current control output information according to the current observation state information; c. Giving said output control information to said controlled plant in the network as feedback, wherein said controlled plant in the network is nonlinear hybrid system. The present invention realizes the control of nonlinear hybrid system through network by providing control method with quantized controller to guarantee the asymptotic stability of the system. Especially, the load capacity of network will be greatly reduced by transmitting the observation information after being quantized. | 02-23-2012 |

| 20110159581 | PHOTOBIOREACTOR FOR CARBON DIOXIDE MITIGATION IN WASTEWATER TREATMENT - An airlift circulation micro-algae photoautotrophic-heterotrophic coupling photobioreactor for wastewater treatment carbon emission mitigation includes feeding pipe, micro-algae heterotrophic zone, gas-liquid separation chamber, micro-algae phototrophic zone, bottom backflow zone, discharge pipe, and the liquid drained zone. | 06-30-2011 |
| 20110155655 | MODULAR INTEGRATED WATER-PURIFYING DEVICE - In a kind of modular integrated water purifying device, including reaction tank, sedimentation tank and filter pool, a pump is connected to the top side of the reaction tank through pipes and valves. There are variable grid hole mixing paddles in the reaction tank, forced outlet pipe at the bottom of sedimentation tank and the same-flow ramp board in the middle. The sedimentation water collector is set up below the board, with the purified water outlet tube connected. The traveling sludge sucker sits on the top of filter tank and move back and forth. Blanket-shape filters is vertically fixed in the filteration tank, the mud-suction pump below to the raveling mud-suction machine connects to the mud-suction pipe another side to the blanket-like wedge filters. At the bottom of the filteration tanker lie the water-collecting main pipe and clean water outlet, the effluent weir is fixed inside of the filteration tank. | 06-30-2011 |
| 20110041424 | Grouted Tubular Energy-Dissipation Unit - The present invention discloses a grouted tubular energy-dissipation unit comprising an inner tube and an outer tube. The inner tube is coaxially inserted into the outer tube defining a gap within a lapping portion of the tubes for receiving expansive cement grout. After solidified, the expansive cement grout forms an expansive ring. A prestress produced by the expansive cement grout increases the friction between the expansive ring and the tubes. In service, the present invention can transfer the axial force via the friction between the tubes and the expansive cement grout. In case of earthquake, the sliding friction between the tubes and the expansive cement grout can absorb energy. The present invention does not require high precise in manufacturing and constructing, saves steel and has low cost. It is only need to replace the grouted tubular energy-dissipation unit when the present invention is damaged in earthquake, which is very convenient. | 02-24-2011 |
