Embodiment 1

[0028] Study on the Degradation Performance of PE / CaO Composite Materials under Reactor Aerobic Composting Conditions

[0029] According to the structure of the present invention, an accelerated reactor for accelerating the performance aging of plastic films by utilizing sludge composting is produced. Take 100kg of fresh sludge with an initial moisture content of 83.55%, add 1kg of sodium polyacrylate and 15kg of sawdust in the weight ratio of sludge: sodium polyacrylate: sawdust=100:1:15, and mix uniformly to form a sludge mixture .

Abstract

The invention relates to an accelerating reactor for accelerating the ageing of the performance of a plastic film by utilizing aerobic or anaerobic composting of high water content sludge. The accelerating reactor is characterized by consisting of a main reaction tank system, a temperature maintaining and controlling system, an agitation system, a ventilation and oxygen control system, a filtraterecharge system and a material accelerating ageing sample bearing system; wherein a main reaction tank of the main reaction tank system is divided into a reaction chamber and a filtrate collecting chamber; in the temperature maintaining and controlling system, an air heat exchanger is positioned in the middle of a blast pipeline, and a temperature sensor is arranged at the outer side of the main reaction tank and extends into the reaction chamber; a motor of the agitation system is positioned at the upper part of the main reaction tank, and an agitating vane is arranged inside the reaction chamber; in the ventilation and oxygen control system, an exhaust hole is positioned above a tank body, and an air inlet is arranged under the tank body; the filtrate recharge system is arranged outsidethe tank body; the material accelerating ageing sample bearing system is arranged on the side wall of the main reaction tank. The accelerating reactor can greatly shorten the plastic ageing test which generally can be realized for one year or a longer time, so as to improve the working efficiency and shorten the study period.

Description

technical field [0001] The invention relates to an aging acceleration device, in particular to an accelerated reactor for anaerobic composting and plastic film performance aging by using sludge with high water content. technical background [0002] 1. About sludge composting [0003] Sludge is a thick substance between liquid and solid, and is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. At present, the main source of sludge is municipal sludge (Civil sludge). Sewage sludge treatment is an environmental problem faced by all countries in the world. Sludge has complex components and high content of toxic and harmful substances, which can easily cause secondary pollution through various channels such as the atmosphere, water body, and food chain, endangering human health. In my country, with the rapid expansion and development of cities in recent years and the continuous improvement of urban sludge t...
