An ecological pollution treatment system for livestock and poultry farms based on combination of planting and breeding, including a source separation water-saving enclosure, a pollution treatment factory, a feed factory and a supporting planting land. The pollution treatment factory and the feed factory are managed by professional teams for specialized disposal of livestock and poultry manure. The pollution treatment factory is composed of a high-temperature aerobic solid fermentation system, a medium-temperature anaerobic liquid fermentation system, a cracking and propagation system, a heating and heat balancing system, a waste gas treatment system and a detection and control system. Sensors of the detection and control system are arranged in the above systems. The present invention can carry out comprehensive treatment on feces, urine and other wastes and waste gases generated during breeding in large-scale pig farms for resource utilization, and is of great significance to rural environmental protection.

A system and method for generating an incubated bacteria solution by heating a nutrient germinant composition and bacteria, including at least one species in spore form, to a preferred temperature a range of 35-50 C. for 2-60 minutes using exothermic chemical reaction heat. An incubated bacteria solution is preferably generated at or near a point-of-use in an aquaculture, agriculture, wastewater, or environmental remediation application. The nutrient-germinant composition comprises L-amino acids, optionally D-glucose and/or D-fructose, a buffer, an industrial preservative, and may include bacteria spores (preferably of one or more Bacillus species) or they may be separately combined for incubation. A first chemical contained in a pouch is activated by contact with a second chemical, water, or air in a flameless heater to initiate exothermic reaction to provide incubation heat. A potable, single-use incubation bag is configured to hold the flameless heater and a container of nutrient germinant composition and spores.

Process for treating solid waste containing an organic fraction, comprising an initial step of extrusion pressing the waste with production of a solid fraction and a liquor. The solid fraction is subjected to a milling treatment at a pressure lower than the atmospheric pressure in a rotary mill that produces a sanitized dry solid and water. The liquor is subjected to a treatment of anaerobic digestion in three subsequent steps, with production of biogas and of a digestate that is subjected to evaporation under vacuum to obtain a concentrated compost and steam, re-used in other steps of the process. The sanitized dry solid and the biogas can be used as fuel to produce thermal and electric energy to be used in the process, which also allows surplus energy to be obtained.

Sludge, for example primary sludge or waste activated sludge or both from a wastewater treatment plant, is pre-treated prior to anaerobic digestion. The pre-treatment includes an optuional mechanical treatment to reduce the viscosity of the sludge and a biological hydrolysis treatment. The biological hydrolysis treatment may be performed in a series of reactors some of which are maintained at a temperature in the range of 50 to 70 C. The reactors provide a combined residence time in the range of 0.5 to 6 days. Optionally, measurements of the pH of the sludge during or after biological hydrolysis, or the production of biogas from a downstream anaerobic digester, may be considered in adjusting the temperature of one or more of the biological hydrolysis reactors.

Disclosed herein is a process for the treatment of wastewater for biosolids reduction and biogas (i.e. methane) generation where a wastewater is provided to a first reactor which is operated under anaerobic conditions, a hydraulic/solids retention time of from 0.1 to 1 day, a temperature of from 30 to 70 C. and a pH of from 6.5 to 10, with the effluent of the first reactor passing to a second reactor which is operated under anaerobic conditions, a hydraulic/solids retention time of from 3 to 10 days and a temperature of from 30 to 70 C. The process may further comprise feeding an effluent produced from the second reactor to a third reactor operated under anaerobic conditions, a hydraulic/solids retention time of from 3 to 20 days and a temperature of from 30 to 70 C.

A method of treating oil and gas produced water may include: receiving produced water from one or more wells; separating an aqueous portion of the produced water from oil and solids included in the produced water in order to provide recovered water; performing anaerobic bio-digestion of organic matter included in the produced water using a biomass mixture of anaerobic bacteria obtained from a plurality of wells; aerating the recovered water in order to promote metal precipitation; and performing aerobic bio-digestion of organic matter present in the recovered water. Some embodiments may also include one or more of anoxic equalization, filtration, pasteurization, reverse osmosis, and biocide treatment of the recovered water. The recovered water may be used for oil and gas well fracking and/or land and stream application. Other methods of treating oil and gas produced water are also described.

Methods and systems are described for treating a fluid that includes a particulate fraction and a soluble fraction, such as wastewater fluid including biosolids. The treatment includes biochemically transforming solids in the particulate fraction of the fluid in a biochemical process while simultaneously subjecting the fluid to a vacuum pressure, and evaporating off at least a portion of the soluble fraction of the fluid and thereby thickening a remaining portion of the fluid. A residence time of the particulate fraction can be controlled to be at least 25% greater than a residence time of the soluble fraction, for example. A solids content of the particulate fraction can be controlled to be in a range of from 2% to 99%, for example.

The present disclosure relates, according to some embodiments, to systems and methods for processing organic compounds, such as manure or other organic waste. Embodiments may comprise a first containment chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, a sulfide gas treating unit may receive and treat sulfide gases from a first anaerobic chamber and/or a second anaerobic chamber. A water storage unit may receive and store waste water or effluent from a first anaerobic chamber and/or a second anaerobic chamber.

A portable renewable energy microgeneration system is disclosed. The system comprises one or more holding tanks that are configured to perform anaerobic digestion on waste in a multi-phase process using bacteria and a controller configured to automatically control the multi-phase process and to re-use the bacteria. The controller re-uses the bacteria by removing at least a portion of the liquid from the waste after anaerobic digestion is performed on the waste and using the at least a portion of the liquid to wet other waste and repeat the multi-phase process.

The present process relates to thermally hydrolyzing sludge in a thermal hydrolysis system. A flash tank or waste heat boiler is located downstream of the thermal hydrolysis system. Hydrolyzed sludge is continuously directed into the flash tank or waste heat boiler for recovering supplemental steam. The supplemental steam is used independently or in combination with live steam produced by a main boiler to heat sludge being directed into the thermal hydrolysis system.
