An apparatus for the fixed-film anaerobic digestion of flushed livestock manure includes an enclosed digester tank (fixed or flexible roof), internal media for biofilm development, a biogas collection and flare system, various pumps, and hydraulic control systems. The preferred media has substantially vertically-oriented, uninterrupted channels to promote enhanced bacterial attachment and biofilm development. The immobilization of microbial biomass within the reactor as a biofilm allows effective treatment of the wastewater at ambient and higher temperatures, as well as reasonable hydraulic retention times. The composition and concentration of bacterial groups in the biofilm developed on the media in the fixed-film digester result in a significantly enhanced anaerobic degradation process. This novel fixed-film digester design expands the potential application of anaerobic digestion to dilute livestock waste with significant levels of suspended solids. This holistic manure treatment system not only stabilizes the wastewater but also produces energy (biogas), controls odors, reduces pathogens, minimizes environmental impact from waste emissions, and maximizes fertilizer and water recovery for reuse.

Proposed are a system and method for wasteless pyrolytic processing and complete utilization of municipal and domestic wastes. The wastes are sequentially passed through units of sorting, grinding, drying, accumulating, and sending to a pyrolysis reactor for pyrolytic treatment. The syngas produced in the pyrolysis is passed through dry cleaning, dust catching, a first wet cleaning with water, a second wet cleaning with alkali, and a floatation unit for separation of water which is purified to an extent sufficient for technical use. The purified syngas is also passed through an absorber and is then used as a working medium for a power generation unit such as a gas turbine co-generator that generates electricity. Solid products of the pyrolysis reaction, such as coke, are returned to the reactor for afterburning, and the heat of the reaction can be utilized in a dryer, or the like.

Methods and systems to achieve clean fuel processing systems in which carbon dioxide emissions (1) from sources (2) may be processed in at least one processing reactor (4) containing a plurality of chemoautotrophic bacteria (5) which can convert the carbon dioxide emissions into biomass (6) which may then be used for various products (21) such as biofuels, fertilizer, feedstock, or the like. Sulfate reducing bacteria (13) may be used to supply sulfur containing compounds to the chemoautotrophic bacteria (5).

A gasification-liquefaction disposal method, system and equipment for MSW are disclosed. The method involves the MSW pretreatment of dehydrating and separating, thus reducing water and inorganic substance content of the waste. Then, the MSW is introduced into a plasma gasifier (23) by a carbon dioxide air-sealed feeding device (13) and gasified therein to obtain hydrogen-rich syngas. The hydrogen-rich syngas is then cooled, deacidified, dedusted and separated to obtain carbon dioxide. Then, the hydrogen-rich syngas is catalyzed to produce methanol product in a methanol synthesis reactor (52). The separated carbon dioxide is sent back to a carbonation reaction chamber (2007) of a gasification system to perform carbonation reaction with calcium oxide, thereby releasing heat to provide assistant heat energy for gasification and avoiding greenhouse gas from being discharged into environment. Exhaust gas is returned to the plasma gasifier (23) for remelting treatment, thus forming a closed-loop circulation production system and realizing the disposal of the MSW with zero discharge and no pollution, thereby avoiding dioxin pollution and converting the MSW to chemical raw materials and fuel needed by mankind. The method, system and equipment are suitable for harmless and recycling disposal of MSW, industrial high polymer waste, composting waste and waste in waste sorting sites.

A pitch system of a wind energy system includes an emergency energy store for moving a rotor blade into a safety position in the event of the failure of an external energy supply. The emergency energy store can be tested, for example to assess aging, by supplying electrical energy to an actuating device configured to set a pitch angle of a rotor blade even in a normal operating mode of the wind energy system temporarily exclusively from the emergency energy store. This configuration ensures reliable operation of a wind energy system.
