Belt dryer is a common drying equipment. Its working principle is to send the high humidity material into the dryer through the conveyor belt. After heating, the water gradually evaporates, and then the moisture is discharged through the exhaust fan, so as to achieve the purpose of drying.

Specifically, the belt dryer is mainly composed of conveyor belt, heater, fan and so on. The material is transmitted to the heater through the conveyor belt, and the water on the surface of the material begins to evaporate after being heated by the hot air in the heater. As the material moves, the water gradually evaporates until the material is completely dry. The exhaust fan pulls the air with water vapor out of the dryer, so as to ensure that the relative humidity inside the dryer is lower than the ambient humidity and ensure the drying effect of the material. Finally, the material is exported from the outlet of the dryer and the whole drying process is completed.

Belt dryer has the advantages of fast drying speed, high efficiency and good drying quality, which is widely used in food, chemical, pharmaceutical and other industries. At the same time, when using the belt dryer, it is necessary to pay attention to the input amount of materials, temperature, humidity and other factors to ensure the stability of the drying process and the drying effect of materials.

Filter press sludge dewatering machine is a widely used equipment in industry, which can effectively separate solids from liquids. Filter press functionality is derived from high-pressure operation, which compacts the solid filter cake and minimizes moisture content. This core technology solves the solid-liquid separation problem in many industries and is an important part of industrial production.

The operation of the sludge dewatering filter press consists of several steps. First, the slurry (a mixture of solid and liquid) is delivered to the filter press under high pressure. Then, the corresponding filter media (such as filter cloth) will trap the solids in the slurry and allow the liquid to pass through. The separated liquid, also called filtrate, is discharged through a system of pipes. In this process, the high pressure not only effectively separates the solid, but also compreses the moisture of the filter cake and improves the drying degree of the filter cake.

Many uses of water in cities, such as cooling, flushing, building, irrigation, etc., do not require high water quality. Sewage utilization technology has been developed and mature, and water treatment technology can fully meet its technical support.

Second, from the perspective of water quantity, urban sewage volume and water consumption are almost equivalent, and rainwater has the characteristics of seasonality and randomness, which can be used as urban reclaimed water.

Third, from the perspective of engineering construction, the use of urban sewage and rainwater need to use equipment far smaller than the use of tap water required by the amount of engineering.

Four, from the economic point of view, not only save pure water resources, but also reduce the cost of sewage, reduce the cost, there are significant economic benefits.

Domestic sewage treatment is an important role in water resource management in urban and rural areas, with the following applications and implications:

1. Protection of water resources: through the treatment of domestic sewage, reduce the pollution of water resources and protect the sustainable use of water resources.

2. Prevention of disease transmission: The treatment of domestic sewage can effectively kill pathogenic microorganisms and reduce the risk of disease transmission.

3. Improve environmental quality: domestic sewage treatment can reduce water and soil pollution, improve environmental quality,

4. Promote sustainable development: Domestic sewage treatment can improve the utilization efficiency of water resources and promote sustainable development of urban and rural areas.

Through domestic sewage treatment, environmental pollution can be reduced, sustainable use of water resources can be protected, and people's living environment can be improved.

The pollution caused by industrial wastewater mainly includes: organic aerobic material pollution, chemical toxicant pollution, inorganic solid suspended matter pollution, heavy metal pollution, acid pollution, alkali pollution, plant nutrient pollution, thermal pollution, pathogen pollution, etc. Many pollutants have color, odor or foam, so industrial wastewater often presents an aversive appearance, resulting in large areas of water pollution, directly threatening people's life and health, so it is particularly important to control industrial wastewater.

A characteristic of industrial wastewater is that the water quality and quantity vary greatly depending on the production process and mode of production. Such as electricity, mining and other sectors of the wastewater mainly contains inorganic pollutants, and paper and food and other industrial sectors of the wastewater, organic matter content is very high, BOD5(five-day biochemical oxygen demand) often more than 2000 mg/L, some up to 30000 mg/L. Even in the same production process, the water quality in the production process will change greatly, such as oxygen top blowing converter steelmaking, different smelting stages of the same furnace steel, the pH value of wastewater can be between 4 ~ 13, suspended matter can be between 250 ~ 25000 mg/L.

Another characteristic of industrial wastewater is: in addition to indirect cooling water, it contains a variety of materials related to raw materials, and the existence form in wastewater is often different, such as fluorine in glass industry wastewater and electroplating wastewater is generally hydrogen fluoride (HF) or fluoride ion (F-) form, and in phosphate fertilizer plant wastewater is in the form of silicon tetrafluoride (SiF4); Nickel can be in ionic or complex state in wastewater. These characteristics increase the difficulty of wastewater purification.

The amount of industrial wastewater depends on the use of water. Metallurgy, paper making, petrochemical, electric power and other industries use large water, the amount of waste water is also large, such as some steel mills smelting 1 ton of steel waste water 200 ~ 250 tons. However, the actual amount of wastewater discharged from each factory is also related to the recycling rate of water.
