Motor vehicle exhaust is an important cause of air pollution. Recently, the reporter learned from the Xi'an Motor Vehicle Exhaust Pollution Supervision and Monitoring Center that this year Xi'an will accelerate the elimination of “yellow standard vehicles†and old vehicles. 18,000 yuan.
The reporter learned that the scope of subsidies includes non-financial support for the operation of “Yellow Label Vehicles†and old vehicles. The operating conditions specified in the National Motor Vehicle Compulsory Scrap Standards Regulations are defined as the standard, and the operating vehicles that have been scrapped more than one year in advance are given. subsidy.
Among them, operating vehicles: According to the relevant regulations, trucks: from the national mandatory retirement period of 5 years (including more than 5 years) to be phased out in advance, according to the type of vehicle in accordance with national regulations, full subsidies, heavy vehicles per vehicle subsidy of 18,000 yuan For medium-sized vehicles, each subsidy is 13,000 yuan, light vehicles are subsidized at 9000 yuan per vehicle, and micro-vehicles are subsidized at 6,000 yuan per vehicle. If the national mandatory retirement period is 1 year (including 1 year) to 5 years before the phase-out, according to the above full standard 60% subsidy. Passenger cars: If the national mandatory retirement period is 4 years (including more than 4 years), the subsidies will be fully subsidized. The subsidies for large vehicles will be 18,000 yuan, the subsidies for medium-sized vehicles will be 11,000 yuan, and the subsidies for small vehicles will be 7,000 yuan per vehicle. Yuan, micro-vehicles subsidize 5,000 yuan per vehicle; from the national mandatory retirement period of 1 year (including 1 year) to 4 years early elimination, 60% subsidy according to the above full standard.
Non-operating vehicles: According to relevant regulations, trucks: 6,000 yuan for each heavy-duty vehicle, 45 million yuan for medium-sized vehicles, 3,000 yuan for each light-weight vehicle, and 2,000 yuan for each micro-vehicle. Passenger cars: 6,000 yuan for each large vehicle, 4,000 yuan for each medium-sized vehicle, 2,500 yuan for each small vehicle, and 2,000 yuan for each small vehicle. Cars: 1.6 liters and above for each car, the subsidy is 6,000 yuan, 1 liter (excluding) - 1.6 liters (excluding) displacement cars, each subsidy of 3,500 yuan, 1 liter and below displacement cars, special work vehicles, each The subsidy is 2,000 yuan.

Polyacrylamide (PAM) is a water-soluble polymer, which is insoluble in most organic solvents, has good flocculating properties, can reduce frictional resistance between liquids, Can be divided into non-ionic, anionic, cationic and amphoteric four types.
When PAM is used for flocculation, it is related to the surface properties of the species being flocculated, especially the potential, viscosity, turbidity, and pH of the suspension. The kinetic potential of the particle surface is the reason for particle inhibition. Can reduce the potential and condense.
Granular polyacrylamide flocculant cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution are used to treat sewage.The water in which the particulate polymer is dissolved should be clean. Generally tap water is suitable for formulating polymer solutions. Strong ACID, strong alkali, high salt water is not suitable for preparation. Water at room temperature is ok, no necessary to heat. Dissolution is slow when the water temperature is below 5 ° C. Increasing the water temperature will accelerate the dissolution rate, but above 40 ° C will accelerate the degradation of the polymer and affect the use effect. The solution concentration is recommended to be 0.1% -0.3%.
