摘要： There is provided a method of hydrothermal carbonization of a sludge, comprising the steps of: preheating the sludge to obtain a preheated sludge; mixing the preheated sludge with a wet-oxidized fraction to obtain a reaction mixture; subjecting the reaction mixture to hydrothermal carbonization (HTC) in a reactor to obtain a HTC-treated sludge; separating a fraction from the HTC-treated sludge; and mixing the fraction with an oxidizing agent, such as oxygen gas, to obtain the wet-oxidized fraction, wherein the temperature of the fraction before the wet oxidation is at least 15° C. higher than the temperature of the preheated sludge. A corresponding system is also provided.

摘要： Provided is a sludge drying composite conditioner. The sludge drying composite conditioner comprises a Fenton's reagent or/and Fenton-like reagent and a matrix construct, the weight ratio between the Fenton's reagent or/and the Fenton-like reagent and the matrix construct is 1:0.05 to 300, and the matrix construct is powder. Further provided is an application method of the sludge drying composite conditioner, which comprises the steps of: adding a Fenton's reagent or/and Fenton-like reagent in a sludge, performing stirring and mixing, and performing an oxidation reaction; and adding a matrix construct to the sludge added with the Fenton's reagent or/and Fenton-like reagent and performing stirring and mixing. For the sludge drying composite conditioner, through the coordinated effect of the Fenton's reagent or/and Fenton-like reagent and the powder matrix construct, the extracellular polymeric substances in the sludge are effectively damaged, the compressibility of organic matter is reduced, and the drying performance of sludge is improved. The application method thereof has a simple working process and easily controllable conditions and reduces the drying time for sludge, thereby achieving large-scale treatment of sludge.

摘要： A system or method converts long carbon chain fractions of crude oil into highly-branched liquefiable hydrocarbons by cavitating long carbon chain fractions of crude oil with natural gas. The cavitated long carbon chain fractions of crude oil are irradiated with an electron beam in combination with an electron beam sustained non-thermal plasma discharge to create short carbon chain fractions. The short carbon chain fractions are enriched with natural gas and irradiated with an electron beam in combination with an electron beam sustained non-thermal plasma discharge. The irradiated gas mixture is cooled so that the liquefiable highly-branched hydrocarbons can be removed.

摘要： A water treatment system (100) incorporating a solubles concentration reduction device (104) between a powdered activated carbon treatment (PACT) system (106) and a wet air regeneration (WAR) system (108). Soluble components may be removed by sequentially dewatering (20) then re-slurrying (28) spent carbon sludge (18). The reduced concentration of soluble materials reduces the need for scale removal maintenance and eliminates the necessity for exotic materials of construction of the WAR system components. The solubles concentration reduction device also facilitates active control of the solids concentration being delivered to the WAR system.

摘要： A supercritical water oxidation treatment system for organic wastewater with a high salinity crystallizes high-salinity wastewater by a low temperature of liquid oxygen, and decreases an inorganic salt content in the wastewater. Under supercritical water conditions, a hydrocyclone (4) separates most precipitated solid salts in the wastewater, so effectively prevents pipes and the tubular reactor (22) after the hydrocyclone (4) from plugging. Inorganic salts are able to be continuously separated from the system by the hydrocyclone (4) at the bottom of a desalination device, In addition, excess oxygen and gaseous products CO2 are recovered by a separation recovery part. The reaction time and the reaction temperature of supercritical water oxidation reaction are lowered due to the installation of a simple post-treatment unit (37). Moreover, the heat of the reactor effluent with a high temperature is recovered in the system, so operation cost of the system is reduced evidently.
