The disclosure relates to a treatment method for sludge utilization in a sewage treatment plant, in particular to a method for reducing heavy metal content of sludge-based biocoke. The disclosure includes following steps (1) to (5): step (1): concentrating a residual sludge produced by a municipal sewage treatment plant to be with a moisture content of 95-98%; step (2): conditioning the concentrated sludge in a sludge bioleaching tank for 48 hours, with a pH value of the sludge being reduced to below 4.5; step (3): pumping the conditioned sludge into a high-pressure diaphragm plate and frame for a press filter dewatering to obtain a dewatered cake with a moisture content less than or equal to 50%; step (4): delivering the dewatered cake into a sludge dryer for crushing, heating and drying to obtain the dried sludge with a moisture content of 15-22%; and step (5): carbonizing the dried sludge into sludge-based biocoke at a high temperature in a pyrolytic carbonization device with a carbonization temperature of 500-650.

Methods of delivering microorganisms loaded onto an inorganic porous medium. Methods of treating wastewater to increase effluent and biosolids quality. Methods of reducing ammonia and denitrifying wastewater effluent. Methods of reducing phosphorous concentration in wastewater effluent. Composition of biosolids derived from wastewater treatment. Wastewater treatment assemblage for increasing wastewater effluent and biosolids quality.

There is provided an apparatus for extraction of at least one object from a cavity. The apparatus includes a sleeve including an inflatable section configured to surround the at least one object during inflation; a handle configured to enable a user to hold the sleeve, the handle defining a holding edge of an opening at a first portion of the sleeve; and a handle-mount mounted to a peripheral area around the opening, the handle-mount being for attachment of a pump used for inflating the inflatable section. There is also provided a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit.
