Sewage sludge refers to the semi-solid or solid substance produced in the sewage treatment process, which can be divided into domestic sewage sludge and industrial sewage sludge according to its source. Domestic sludge refers to solid precipitated substances produced from domestic sewage treatment systems.Industrial sewage sludge refers to the sludge produced after the treatment of wastewater produced in the industrial production process. Its sources are very wide, including petrochemical, pharmaceutical, paper, textile, printing and dyeing industries. Some of the sewage sludge produced in the production and discharge process of these industries contains a large number of toxic and harmful substances, most of which should belong to the category of hazardous waste.

Major industrial production workshops should also pay attention to the problem of welding smoke.

Reverse osmosis equipment RO system working principle:Osmosis technology is a mature membrane liquid separation technology, which applies operating pressure on the inlet (concentrated solution) side to overcome the natural osmotic pressure. When the operating pressure higher than the natural osmotic pressure is added to the concentrated solution side, the flow direction of the natural osmosis of water molecules will be reversed, and the water component in the inlet (concentrated solution) will become the purification water on the dilute solution side through the reverse osmosis membrane.

Industrial waste gas treatment refers to the treatment and purification of waste gas generated in the industrial production process to reduce the harm to the environment and human health.Industrial waste gas is all kinds of industrial enterprises in the production process of some of the waste gas, according to the different types of industry produced by the gas contains different substances, but most of them are harmful to the atmosphere and human body some substances, so the industrial waste gas output enterprises must be the waste gas treatment work as an important work in the production process to do. According to the different nature of industrial waste gas, the waste gas treatment process we take will also have some differences.

Activated carbon (English: Active charcoal), also known as activated carbon, activated charcoal, activated charcoal or activated carbon, is a black powdered or granular carbon substance. Activated carbon is structurally due to the microcrystalline carbon is irregularly arranged, there are fine pores between the cross-connections, in the activation will produce carbon organisational defects, so it is a kind of porous carbon, low packing density, large specific surface area, but also to do a filter of the main material.

Dry mechanical dust collector mainly refers to the dust removal equipment designed for the application of dust inertia and gravity, such as high-concentration dust collectors such as settling chambers, inert dust collectors, and cyclone dust collectors, etc., mainly for the separation of high-concentration coarse-grained dust Or concentrated and used.
