Brief introduction of harmless treatment technology of oil sludge
With the increasing awareness of environmental protection and strict environmental standards, oil sludge, a dangerous solid waste containing petroleum resources, must be detoxified, reduced, and resourced. At present, for the treatment of oil sludge, domestic and foreign scholars and petrochemical-related enterprises have carried out a lot of research and formed a variety of oil sludge […]
Characteristics and hazards of oil sludge
The oil sludge is mainly composed of three phases of water, oil and slag. The characteristics of oil sludges of different types and different sources vary greatly. The content of the three-phase components in the oil sludge will directly determine the available value of the oil sludge, and also processing this type of oil sludge […]
Composition of Municipal Solid Waste and Its Regional Impact
Composition of municipal solid waste (MSW) is one of the key parameters directly affecting the selection of waste treatment methods and the design and planning of treatment facilities. It is a dependent variable affected by many factors, such as geographical environment, energy structure, economic development, living habits, living standards, climatic characteristics and waste recycling. According […]
Routes, classification and management measures for solid waste generation
The treatment of solid waste can effectively dispose of waste, reduce the discharge of final waste, reduce the environmental pollution to the area, prevent the spread of secondary pollution, and at the same time achieve low total treatment cost and high resource utilization efficiency. And how is the path and classification of solid waste generated? […]
Brief Introduction of Technology for Disposal of Dangerous Waste in Cement Rotary Kiln
principle Cement rotary kiln is the main equipment of cement clinker dry and wet production line. Rotary kiln is widely used in gold treatment, chemical industry, building refractories, environmental protection and other industries. A large number of research and practice show that the cement rotary kiln has high combustion temperature, long residence time in the […]
10 Tips for Energy Saving and Consumption Reduction in Concentrators
Energy saving and consumption reduction has become a very important task in the sustainable development of concentrators. We should take various effective measures to improve production efficiency, reduce energy consumption, and then improve the economic and ecological benefits of concentrators. The common methods of energy saving and consumption reduction in concentrators are as follows: 1. […]
Source and classification of oil sludge
Oil sludge is generally considered to be a mixture. The main components are: crude oil or refined oil, other organic components, mud, and water. It is a concomitant product produced during oil exploitation, oil wastewater treatment, petroleum refining, and petroleum production and processing. According to different sources of oil sludge, it can be divided into […]
Pollution status of oil sludge in China
In recent years, although the pace of development of the petrochemical industry has gradually slowed down, demand and consumption are still increasing, and it is still the pillar industry of today’s world. While the petrochemical industry is developing, it has generated a large number of environmental pollution problems. In the process of exploitation, oil will […]
Environmental impact of municipal sewage sludge
For the most commonly used minicipal sewage secondary treatment process-activated sludge process (including various deformation processes), some of the pollutants in the incoming sewage are removed by conversion to sludge. Therefore, municipal sewage sludge contains a wide range of pollutants, including various heavy metals, trace amounts of highly toxic organic matter (PCBs, AOX, etc.), and […]
