When was the first domestic sewage suction and purification vehicle born?

答

Our city has successfully developed the first domestic sewage suction and purification vehicle, which is expected to be popularized and applied in sanitation units, large enterprises and farms in the future. "For a long time, cleaning septic tanks has mainly relied on manual labor or sewage suction trucks. But both methods have certain defects." Saishun Environmental Protection The person in charge said that due to the harsh environment of this work, if relying on manual labor , not only labor-intensive, low efficiency, but also prone to the problem of incomplete cleaning. However, using a fecal suction truck for cleaning, it can only be transported to a designated location after extracting the dirt. The round-trip transportation is not only time-consuming, but also affects the operation efficiency. "For example, to clean the septic tank of a large-scale complex, in general, it takes 8 people to clean up for 3 days, but if a sewage suction and purification vehicle is used, it can be completed in 8 hours by 3 people." The person in charge introduce. Because all processing is done on-site in a relatively closed circulation system, there will be no leakage of dirt and peculiar smell during operation and transportation, so it will not cause secondary pollution to the environment.   It is understood that this sewage suction and purification vehicle developed by an enterprise in our city has realized more than 90% of mechanized operations, not only cleaned thoroughly, but also "carried" a compressing and drying septic tank sewage treatment machine, which is completely processed on site. , Sewage is discharged by municipal pipelines, and the dung is treated as domestic waste, or made into organic fertilizer, which is not transported back and forth, and the purification of color steel plate greatly improves the efficiency. Is the cost of using mechanized equipment very high? "Actually, the cost of using this sewage suction and purification vehicle is lower." According to the person in charge, the cost of manually cleaning the septic tank is about 1.5 yuan per square meter, but the cost of using suction and purification The cost of sewage purification vehicles is only 1 yuan per square meter, which is reduced by 1/3. Moreover, since the cleaning of mechanized equipment is more thorough, for a building, it is enough to clean the septic tank once a year, and if it is cleaned manually, it will be twice a year. In this way, more cost can be saved.   It is understood that similar sewage purification vehicles are only produced in the United States. Through independent research and development, enterprises in our city have mastered relevant key technologies. At present, the product has not only obtained 1 invention patent and 1 utility model patent authorization, but also included in the municipal key new product and high-tech product plan.

问

Does my country's color steel plate partition wall industry need to be more vigilant?

答

The characteristics of the color steel prefab house's light weight, spliced ​​installation and optional cutting determine the ease of installation of the prefab house, which can greatly improve the efficiency and save the construction period. The surface material and thermal insulation material of the fireproof color steel plate sandwich panel are non-combustible materials, which can fully meet the fire protection requirements of the prefab house. Various studies on durability have shown that it has been widely used in foreign countries for more than 40 years. The shelf life of color steel plates treated with special coatings is 10-15 years. After that, anti-corrosion coatings are sprayed every 10 years. The clear lines of the color steel plate are as many as dozens of colors, which can meet the needs of any style of mobile room color steel plate to achieve satisfactory results.   Color steel plate coating is a product made of cold-rolled steel plate and galvanized steel plate, after chemical treatment on the surface, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. Some people also call this product "pre-rolled color steel plate" and "plastic color steel plate". Color plate products are produced in coils by manufacturers on a continuous production line, so they are also called color-coated steel coils. Color steel plate not only has the properties of high mechanical strength and easy forming of color steel plate material, but also has good decoration and corrosion resistance of coating material. Color steel plate is an emerging material respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, color steel prefab houses are increasingly showing strong vitality and broad market prospects. Favored by interior decoration, office appliances and other industries.   The color steel plate movable room has the advantages of light weight, high strength, thermal insulation, beautiful and durable, etc. It is a high-grade color steel plate that integrates color steel plate and decoration. The color steel prefab house is clean in construction and is widely used in large-span workshops, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary housing. Light color steel sandwich panels with a weight of less than 14KG per square meter can fully reduce the structural load and reduce the structural cost of the prefab.
