The present invention provides an integrated system for treatment of biodegradable waste, including sewage sludge, forestry waste, food waste, agricultural waste, municipal waste, and the like. The integrated system comprises an anaerobic reactor, at least one aerobic reactor, a filtration device, and a desalinization device.

The present invention is a composting bioreactor system that can be continually fed with biodegradable solid wastes, waste waters and exhaust gases, that can automatically recycle the biodegradable wastes into liquid nutrients and heat energy, and that automatically supplies the nutritious liquid and heat into the integrated hydroponics system or aquaponics system. The invention together with the integrated food growing system can be installed onsite in places such as household balconies, household backyards and premises of restaurants and food factories etc. therefore can lead to zero mileage targets both for recycling the wastes and for growing the foods consumed in the same location. It can fully recover and reuse all the nutrients and heat energy from the treated wastes. It can also reach the target of nearly zero pollution to the environment during all processes. For better operational efficiency, an oblique cone agitator, a fish plow agitator and a vortex flower turbine are specially designed for the bioreactor system.

The invention relates to a fully biodegradable garbage bag film blowing device. The fully biodegradable garbage bag film blowing device comprises a feeding device for feeding, a film blowing port connected with the feeding device, a film bubble protection device arranged at the film blowing port, a film blowing channel, an inverted-V-shaped support and a traction device. The feeding device comprises a feed port used for containing plastic particles and a feeding channel used for delivering the plastic particles to the film blowing port. A wind disk used for blowing bubbles is arranged on the film blowing port. The film bubble protection device is connected with the film blowing channel and the film blowing port. A temperature sensor used for detecting the temperature of the film bubble protection device is arranged on the film bubble protection device. The film blowing channel is of a simple structure. The inverted-V-shaped support comprises a first pressing plate and a second pressingplate which are arranged in an inverted-V shape. The film blowing device provided by the invention can guarantee that the temperature of film bubbles blown out from the film blowing port is free frompollution of the external environment.
