摘要： A process for treatment of municipal wastewater plant sludge to the criteria of Class A biosolids. The process uses hydrogen peroxide and thermo-oxidation to reduce volatile suspended solids to meet the criteria. On a batch basis, waste activated sludge is introduced into a reactor; the concentration of the waste activated sludge is adjusted to about 1.5% total suspended solids with secondary effluent, if necessary; the reactor is mixed; the reactor is pre-heated to an operating temperature in a range of about 65° C. to about 90° C.; subsequently, a 50% solution of laboratory grade hydrogen peroxide is introduced into the bottom of the reactor; and the contents are heated for at least 4 hours.

摘要： A wastewater treatment plant that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor to a hydrodynamic separator (HDS) system, where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system via a first output to a clarifier, and the high concentration wastewater stream is passed via a second output back to the bioreactor. The clarifier performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.

摘要： An anaerobic digester is fed a feedstock, for example sludge from a municipal wastewater treatment plant, and produces a digestate. The digestate is dewatered into a cake. The cake may be dried further, for example in a thermal drier. The cake is treated in a pyrolysis system to produce a synthesis gas and biochar. The gas is sent to the same or another digester to increase its methane production. The char may be used as a soil enhancer.

摘要： A system comprises a rotting sedimentation tank with a particulate solids filter, a distribution well, an exposed reservoir with drainage of PVC pipes and insulation of PVC foil, and an inspection well at the reservoir outlet. The reservoir is filled with layers of gravel and sand, planted with hydrophilic vegetation. The filter bed is composed of three layers, the bottom layer filled with coarse-grained oval gravel, in which the dispersal drain is at ⅔ of the height connected with a supply pipe to the distribution well and terminated with the ventilation chimney, the intermediate layer filled with fine-grained oval gravel, and the top layer filled with sand, in which the collecting drain with an outlet to the inspection well is laid. The level of the sewage in the rotting sedimentation tank is located below the level of the collecting drain.

摘要： Moving bed media serving as a growth surface for bacteria that remove soluble carbonaceous BOD, soluble inorganic ammonia nitrogen, phosphorous, nitrate nitrogen or nitrite nitrogen from wastewater are contained in a variable liquid depth, variable volume, hydraulic flow equalization basin. The equalization basin can be divided into different treatment sections by installing separator screens. Fat accumulation on the moving media, which could cause the media to float or in some other way cause the media to be ineffective, can be prevented by a fat, oil, and grease removal process in a dissolved air flotation cell upstream of the flow equalization basin containing the moving bed media. The moving bed media are retained in the basin by a suitable media screen as the liquid level and volume increases or decreases in the basin depending upon the effluent pumping rate vs. the influent flow rate.
