Active sludge is a general term for microbial populations and the organic and inorganic substances to which they belong. It was discovered in 1912 by Clark and Gage in the United Kingdom. Activated sludge can be classified into aerobic activated sludge. And anaerobic granular activated sludge, activated sludge is mainly used to treat sewage wastewater. […]
The sewage from the municipal sewage treatment plant refers to the solid, semi-solid and liquid wastes produced after sewage treatment. It contains a large amount of organic matter, heavy metals, pathogenic bacteria and pathogenic bacteria, etc., without any treatment, it will cause serious damage to the environment. Pollution. The overall requirements for sludge treatment are […]
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 […]
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 […]
At present, there are two main ways of collecting municipal solid waste: mixed collection and classified collection. Whether it is mixed collection or classified collection, it should be realized by different collection methods. According to the packaging mode, the collection methods of domestic waste can be divided into bulk collection and closed collection. Due to […]
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 […]
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? […]
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 […]
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. […]
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 […]
