Jun 20, 2012 · Purpose Urbanization and industrialization in China has resulted in a dramatic increase in the volume of wastewater and sewage sludge produced from wastewater treatment plants. Problems associated with sewage sludge have attracted increasing attention from the public and urban planners. How to manage sludge in an economically and environmentally acceptable manner is one of the critical issues
The lower base part is distributed with hydraulic stations, scroll air pumps, oil cylinders, heating systems and stirring shafts, etc.; the middle part is a double-layer insulated tank, equipment automatic control system, export device, etc. The inner wall of the tank is lined with 304 stainless steel.
Composting is another fantastic method to turn waste into nutrient-rich soil amendments for your garden, especially when you’re looking to support native plants. One exciting composting technique I recommend giving a try is vermicomposting, which utilizes worms (usually red wigglers) to break down organic materials like food scraps and yard
2.1 Objectives and scope. To compare the carbon emissions of two sludge composting technologies, this study took 1 ton of excess sludge (80% water content) from a wastewater treatment plant as the research object. The two sludge composting technologies investigated were aerobic composting and vermicomposting.
It can process river sludge, sewage sludge, etc., and turn it into organic fertilizer through fermentation. The processing capacity of the sludge fermentation tank ranges from 7 to 10 cubic meters per day (the water content is 50 to 70%). We can customize implementable solutions according to your needs.

Urban sludge compost tank. Can treat river sludge, sewer sludge, etc. and turn it into organic fertilizer through fermentation. Tank closed. Thermal insulation.
Jan 14, 2021 · 28 Citations. Metrics. In present study, the effects of carbon sources on compost process and quality were evaluated in the lab-scale sewage sludge (SS) composting. The composting experiments were
The problems posed by fecal sludge (FS) are multidimensional because most cities rapidly urbanize, which results in the increase in population, urban settlement, and waste generation. Issues concerning health and waste treatment have continued to create alarming situations. These issues had indeed i
Mar 1, 2010 · The aim of this work is the study of recycling urban primary sludge by in-vessel aerobic composting way. Two series of composting trials were carried out in an automated accelerated bioreactor in
Conclusions The combination of saline water for irrigation with the compost has to be seriously considered as a source of salts and heavy metal pollution for surface and ground waters. Phosphate and trace elements pollution are clearly associated to the use of the composted sewage sludge. Keywords Heavy metals .
