Description

Mobile emergency box magnetic separation integrated equipment

technical field

The invention relates to the field of waste water treatment, in particular to an integrated device for waste water emergency treatment.

Background technique

With the continuous development of society, the acceleration of urbanization, and the economic development to a certain level, my country's sewage discharge has increased year by year. At present, domestic domestic sewage is mainly collected through municipal sewage pipe networks and then transferred to urban sewage treatment plants for treatment. However, at the same time, the distribution of sewage in many places is relatively scattered and it is not convenient for centralized treatment, such as rural areas, newly built residential areas, villa areas, Highway service areas, docks, military garrisons, scenic spots, etc. These areas usually adopt decentralized sewage treatment facilities. For sewage discharged from long-term fixed locations, traditional technology can be used to arrange small-scale sewage treatment equipment, but for temporary and unfixed sewage discharge points such as construction teams, combat troops, and sewage treatment plants, newly built residential areas or victims of disasters Settlement sites, etc., are not suitable for fixed sewage treatment facilities. Therefore, it is of great significance to develop a kind of emergency mobile sewage treatment equipment.

The mobile sewage treatment equipment occupies a small area, has stable water output, high water treatment efficiency and good effect. Magnetic separation technology is used in water treatment engineering, it can be regarded as a new technology. Since the 1960s, the Soviet Union used magnetic coagulation to treat dust removal wastewater from steel mills. At the end of the 1960s, American MIT professor Kom invented a high-gradient magnetic filter. In the 1970s, the United States applied magnetic flocculation and high-gradient magnetic separation to treat steel, Food, chemical, paper and other waste water. In 1974, Sweden began to use the disk method to treat steel rolling wastewater, and in 1975, Japan developed a disk-type "two-second separator". In my country, from the mid-1970s to the early 1980s, the magnetic coagulation method, magnetic disk method, and high-gradient magnetic separation method were used for the treatment of steelmaking and steel rolling wastewater. In recent years, magnetic separation technology has achieved certain research results in the treatment of electroplating wastewater, phenolic wastewater, lake water, food fermentation wastewater, municipal wastewater, iron and steel wastewater, kitchen wastewater, slaughter wastewater, and oil production water. It has been well applied in the actual wastewater treatment.

The magnetic separation technology treats wastewater quickly, has a large processing capacity, and is not affected by natural temperature; the magnetic separation equipment is small in size, simple in structure, easy to maintain, low in operating costs, and occupies less land. These advantages of magnetic separation can be applied in mobile emergency water purification.

Under the action of the rotary filter, the large particle suspended matter is removed; then it flows into the dosing flocculation system by itself, and the waste water is mixed with PAM, PAC and magnetic flocculant in the rapid mixing tank. The suspended solids in the primary and secondary reaction pools form micro-flocs; then enter the solid-liquid separation system, under the action of the disk separator, the micro-flocs are separated from the water, and the treated water that reaches the standard is directly discharged, and the micro-flocs are scraped After being collected by the slag device and the slag conveying device, it enters the recycling system. The magnetic flocculant is separated from the suspended solids and then returns to the system for recycling. The suspended solids are transported out as sludge. All equipment is integrated in the container and can be moved to a place where vehicles can reach to purify polluted water.

The pretreatment system adopts a rotary filter, which can remove suspended solids with a particle size greater than 0.4mm.

The direction of the main shaft of the rotary filter is the same as the width of the container, the water inlet is arranged on the side of the vehicle, and a buffer tank is arranged between the water inlet and the rotary filter.
