Biological decomposition of organic compounds where the organic compounds are part of an aqueous admixture can be accelerated by introducing a bio-accelerant into the admixture. The bio-accelerant can be prepared by combining a first compound selected from the group consisting of, alkali metal formates, alkali metal acetates, alkali metal malonates, alkali metal nitrates, alkali metal adipates, alkali metal salts of propane-1, 2,3-tricarboxylic acid, and alkali metal citrates; and a second compound selected from the group consisting of: alkali metal carbonates, alkali metal bicarbonates, alkali metal dimethyl carbonates, and alkali metal hypochlorites.

A waste reduction system that utilizes organic solids suspended in a waste stream to produce carboxylic acids, which can then be employed as an input to a microbial fuel cell or other biological processes to further enhance biogas production, is provided. The organic waste stream influent undergoes a multistage fermentation process in which fermentative microorganism metabolize the organic waste materials and produce one or more carboxylic acids, especially short chain fatty acids. The carboxylic acids serve as a food source for bacteria within an anode compartment of an MFC that generates useable electricity therefrom.

An apparatus, method and system is provided for treating sewage sludge by dewatering the sewage sludge, heating the sewage sludge being treated to destroy pathogens, and then reducing volatile solids in the sewage sludge being treated through biochemical decomposition to produce a treated biosolids product that meets government regulations for pathogen reduction and vector attraction reduction.

A sewage treatment apparatus comprises an external box body internally being provided with an anaerobic zone, an aerobic zone, a settling zone, a sewage reduction zone and an apparatus zone separated from each other, wherein the anaerobic zone, the aerobic zone, the settling zone and the sewage reduction zone communicate in sequence, the anaerobic zone communicates with a septic tank, the aerobic zone communicates with the anaerobic zone to reflux a part of mixed liquid to the anaerobic zone, the settling zone communicates with the anaerobic zone to reflux a part of active sludge to the anaerobic zone, and the sludge reduction zone communicates with the anaerobic zone or the septic tank; and the apparatus zone is internally provided with a detection unit for detecting various parameters during a sewage treatment process and a controller for controlling working states according to a detection result of the detection unit.

A positive polymer fecal sludge treatment apparatus comprising a trash separator, one end of which is connected with a sludge inlet, and the other end of which is connected with a twin-rotor vacuum water pump. A high-pressure transparent tube is disposed and connected, by a knife valve, between the trash separator and the twin-rotor vacuum water pump. One end of the knife valve is connected with a first material box and a second material box. A first chemical box and a second chemical box are disposed under the first material box and the second material box, and each of the first material box and the second material box is connected with the first chemical box and the second chemical box. The first and second material boxes have a larger volume than a conventional one and thus can store more material and also can perform chemical stirring reaction directly.
