The present application provides a convenient and quickly-assembled rotary composting barrel and a quick assembly method thereof. On the one hand, the solution provides a convenient and quickly-assembled composting barrel, which comprises two lateral plates, a bearing plate and several surrounding plates, wherein the lateral plates and the bearing plate are respectively provided with the first clamping grooves and the second clamping grooves, and nuts are pre-installed in the first clamping grooves and the second clamping grooves, and the surrounding plate is provided with through-holes through which bolts penetrate at corresponding positions; on the other hand, the solution provides a quick assembly method of the rotary composting barrel, in which by screwing bolts with pre-installed nuts, the bearing plate is connected with the surrounding plate first, and then the lateral plates are connected with the surrounding plates at both sides quickly. The existing rotary composting barrel is inconvenient and time-consuming to install. The rotary composting barrel involved in this solution is ingenious in structural design. It is very convenient to install, and the assembly time is shortened by more than half. It is skillful and environment-friendly when used in conjunction with an unloading cart.

The present invention is a composting bioreactor system that continually receives biodegradable solid wastes, waste waters and exhaust gases, automatically recycles the biodegradable wastes into nutrients and heat energy, and automatically supplies the nutrients and heat into an integrated hydroponic or aquaponic system. This invention together with integrated food growing system may be installed onsite such as balconies, backyards and premises of restaurants and food factories etc. therefore may lead to zero mileage targets both for recycling wastes and for supplying foods. This invention integrates composting process and aquaponic technology together and may establish a closed-loop recirculation of both water and gases therefore upgrades aquaponics into compoponics. A compoponic system has both soil and soilless growing beds and mimics nature recirculating nutrients, carbon and energy among human being, animals, microorganisms and plants by way of photosynthesis, slow burning by cellular respiration and burning by combustion.

An exemplary solid waste treatment system can be provided which can include a storage device, an intelligent aerobic fermentation treatment device, a retaining wall-type fermentation area, and an aeration platform. The intelligent aerobic fermentation treatment device can include a traveling trolley, a lifting mechanism, a material pick-and-place mechanism, and a traveling bridge linearly moving in a direction away from the storage device towards the retaining wall-type fermentation area. The aeration platform can be arranged at the bottom of the retaining wall-type fermentation area. The traveling trolley linearly can move on the traveling bridge in a direction perpendicular to the direction away from the storage device towards the retaining wall-type fermentation area. The lifting mechanism can be mounted on the traveling trolley. The material pick-and-place mechanism can be suspended on the lifting mechanism to be raised and lowered in step with the raising and lowering of the lifting mechanism.

A compost leachate distribution device includes a composting chamber for receiving material to be composted and a leachate collection chamber for collecting, via a leachate fluid path, leachate generated during composting in the composting chamber. The device has a leachate mixing arrangement a first inlet for receiving a flow of water, a mixing chamber to which the first inlet leads for mixing water with leachate to form a water/leachate mix and an outlet leading from the mixing chamber to the exterior for exit of the water/leachate mix, wherein the leachate mixing arrangement has dosing means for controlling a rate of flow of leachate from the leachate collection chamber into the mixing chamber.

Disclosed is a bioreactor, especially a plug flow bioreactor, including an agitator running along a longitudinal axis for thoroughly mixing a dry solid biomass that is to be outgassed in a fermentation chamber. In said bioreactor, an agitator shaft is mounted exclusively in two opposite end walls of the fermentation chamber while at least one free end of the agitator is connected to a drive unit outside the fermentation chamber.

A solids separator for use in a composting system for separating solid waste from liquid waste in a stream of waste includes a housing defining a waste inlet for receiving the stream of waste, a liquids outlet for passing the liquid waste, and a solids outlet for passing the solid waste. A separator belt is positioned within the housing and extending between the liquids outlet and the solids outlet, the separator belt defining a plurality of apertures through which the liquid waste passes through the separator belt and into the liquids outlet. A drive cylinder is rotatably mounted within the housing for selectively rotating the separator belt such that a top surface of the belt is moved toward the solids outlet along with the solid waste that is extracted from the stream of waste.

The invention is directed to a process and equipment for use in a process to bacterially decompose organic waste to a dry composted end material wherein organic waste is composted in a composting tank in the presence of oxygen and aerobic bacteria to obtain a wet composted material. The wet composted material is partly removed from the composting tank and dried such to lower the water content of the composted material to obtain dry composted end material.
