According to different sources, wastewater can be divided into two categories: domestic wastewater and industrial wastewater. Domestic sewage: Wastewater produced by people in their daily lives. Industrial wastewater: wastewater discharged during industrial production. (1) Solid pollutants: Solid pollutants are usually expressed by suspended solids (SS) and turbidity. Turbidity: The amount of water transparency
1. National Standards 1) "Quality Standards for Surface Water Environment" GB3838-2002 This standard is applicable to surface water areas with functions such as rivers, lakes, canals, channels, reservoirs in the People's Republic of China. For waters with specific functions, the corresponding professional water quality standards are implemented. 2) "Sewage sludge from urban sewage treatment plants
The first is the decentralized treatment mode, that is, the sewage of farmers is collected according to districts, and it is advisable to combine larger villages or neighboring villages, and each area is treated separately. After the sewage is collected in pieces, the village sewage is treated with small and medium sewage treatment equipment or natural treatment. This treatment mode has the characteristics of flexible layout, simple construction, convenient management, and guaranteed effluent water quality.
Chongqing industrial wastewater treatment equipment to treat wastewater also needs to be classified and treated differently. This is because industrial wastewater is classified, so not all wastewater can be treated with the same equipment. So what are the divisions of industrial wastewater, and what principles does the treatment equipment it uses need to abide by? To determine the division of industrial wastewater, the general
Do you know what are the main processes for sewage treatment? In the process of enhanced biological phosphorus removal sewage treatment, the main rivers and lakes in China are severely eutrophic because of phosphorus pollution. Strict specifications. Cyclic intermittent aeration, the level of economic development in China varies greatly from place to place, and economic development lags
Sewage treatment equipment is the treatment of wastewater from manufacturing plants or aquaculture plants. Sewage treatment equipment brings many advantages to human beings, which not only treats the troubles of domestic sewage, but also makes our living environment better. After purchasing the integrated sewage treatment equipment, it is installed. What are the specifications of the integrated sewage treatment equipment at the time of installation? 1
With the improvement of people's living standards, the discharge of domestic sewage has become increasingly severe. In this form, the domestic sewage treatment process is also continuously improved. Let's take a look at the domestic sewage treatment process and process. Sewage treatment process Aerated biological filter Sewage treatment process introduction: biological aerated filter is the biological filter treatment equipment
How to maintain textile wastewater treatment equipment? What are the requirements? The maintenance requirements for textile wastewater treatment equipment are as follows: 1. Neat tools, workpieces and accessories are placed neatly; safety protection devices are complete; lines and pipelines are complete. 2. Lubricate the oil and change oil on time, and the oil quality meets the requirements; the oil can, oil gun, oil cup, linoleum, and oil line are clean.
With the continuous development of society, the problem of environmental pollution is also increasing. How to deal with industrial sewage has become a problem of general concern in society. Regarding industrial sewage treatment equipment, there are mainly several methods, such as physical treatment method, chemical treatment method, physical chemical method, and biological treatment method. Today, I will introduce the chemical treatment method of industrial sewage treatment equipment. I. Ozoneization of wastewater
The removal of organic pollutants and ammonia nitrogen from sewage treatment equipment mainly depends on the AO biological treatment process in the equipment. The working principle is at level A. Due to the high concentration of organic matter in the sewage and the microorganisms are in anoxic state, the microorganisms are facultative microorganisms. Therefore, the level A pool not only has a certain organic matter removal function, and reduces the organic load of subsequent aerobic ponds. Organic matter concentration drops
Sewage produced by industrial printing and dyeing is relatively complicated, and it is a type of industrial sewage with a large amount of change. The following Chongqing Industrial Wastewater Treatment Equipment introduces the issues that need attention in the use of industrial printing and dyeing wastewater treatment equipment. A common problem in industrial printing and dyeing wastewater treatment is that the amount of aerobic microorganisms in the biochemical treatment is too small, and the amount of flocculant is not well controlled. To print
The quality of water to be treated in slaughtering sewage treatment equipment is slaughtering sewage. The slaughtering sewage mainly comes from the sewage produced in the processes of ring fence washing, leaching, slaughtering, and other plant floor washing, scalding, dissection, non-staple food processing, and oil washing. So what are the characteristics of slaughter sewage? 1. The slaughtering wastewater has high organic matter content, good biochemical properties, and high concentration of organic matter is not easy.
