Disclosed are remote oily water treatment systems, including systems and related methods of remote oily water treatment with point-of-treatment discharge of treated water. In a preferred embodiment, (a) oily water is treated at a location proximate to where the oily water by passing the oily water through a tank containing a medium defined by at least one polymer mixed with activated carbon and (b) treated water is discharged at the point-of-treatment of the oily water.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

The invention relates to a method and a device for improving the biodegradability of an organic sludge. It comprises at least two treatment cycles each of a total duration of between around 8 s and around 20 s and each comprising a first step of producing a first hydrolysed sludge emulsion in a first, reduced zone, by injecting a gas into said reduced zone. a second step of abruptly expanding the emulsion in a second zone—the expansion zone—and a third step of recovering the emulsion via a third, restriction zone.

The invention relates to a method and an assembly for recovering magnesium ammonium phosphate from slurry that is supplied to a reaction container (10) in which an aerobic milieu is present and in which the slurry is guided in a circuit with the aid of ventilation. Cationic magnesium, such as magnesium chloride, is added to the slurry, and magnesium ammonium phosphate crystals which are precipitated from the slurry are removed via a removal device (30) provided in the base region of the reaction container. Substances which contain magnesium ammonium phosphate crystals collected in the removal device (30) are loosened and/or rinsed.

A method for modifying a wastewater treatment device, the method including: 1) fixing a filling support in a wastewater pool, where the filling support includes a support frame; the support frame includes a hollow shaft, a fixed ring, and at least one vane; 2) adjusting the height of the filling support, until the fixed ring is submerged below the liquid level of the wastewater pool, where the water intake velocity of the wastewater pool is no less than 0.25 m/s, whereby a water current is produced and drives the support frame to rotate; 3) adding a functional liquid into the hollow shaft; and 4) adding an enzyme mixture to the hollow shaft when the rotation speed of the support frame is less than a first preset value, until the rotation speed of the support frame reaches a second preset value.

A process for enhanced anaerobic digestion of sludge by alcoholization of food waste, comprising steps of: (1) ethanol prefermentation of food waste—feeding the food waste having been crushed into a uniform grain size into an ethanol production reactor, where the food waste is subjected to rapid and efficient anaerobic fermentation activated by addition of yeast and pH adjustment to produce ethanol and obtain a fermentation broth and a fermentation residue; (2) sludge pretreatment—pretreating the sludge after mixing with the fermentation residue; and (3) methanogenesis of anaerobic digestion—subjecting products resulting from the sludge pretreatment to be mixed with the fermentation broth and then to methanogenesis of anaerobic digestion in a methane production reactor. With this process, the sludge and the food waste can be treated efficiently via multi-phase reactions, and the resource recovery and biogas quality can be enhanced.

A method for sludge dewatering using kitchen waste to synergistically enhance a coupling of an anaerobic biological acidification and a low-temperature hydrothermal of excess sludge is disclosed. The method includes the following steps: first, uniformly mixing the excess sludge from a sewage treatment plant and the kitchen waste for an anaerobic biological acidification reaction at 36.5-37.5° C. for 2-4 days; then, concentrating the acidified mixture by centrifugation at a speed of 3000-5000 rpm for 5-10 min; performing a low-temperature thermal hydrolysis treatment on a residue obtained after removing a supernatant for 15-30 min at 100-140° C.; and after the thermal hydrolysis treatment is finished, cooling and dewatering to obtain a dewatered sludge cake and a dewatered filtrate. The new method realizes high-efficiency sludge dewatering and innocuous utilization of dewatered filtrate and sludge cake without adding chemical reagents and effectively avoids generating hardly-degradable chemical oxygen demand.
