Recently, the 12 ministries and commissions of the country jointly issued the "Strengthening the "Car, Oil, Road" Coordination, Accelerating the Comprehensive Prevention and Control Plan for Motor Vehicle Pollution (hereinafter referred to as the "Program"), and will promote the development of new energy vehicles, automobile environmental management systems and urban roads. . The "Plan" clearly stated that it is necessary to basically phase out yellow-label vehicles and fully use the national five-standard gasoline and diesel before 2017, and vigorously promote the popularization of new energy vehicles to establish a new automobile social management system.
Basic elimination of yellow label cars within 3 years
According to the objectives of the "Program", on the basis of the elimination of 6 million yellow-label vehicles and old vehicles this year, the yellow-label vehicles will be basically phased out in the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions before the end of 2015; The yellow label car was basically eliminated.
On the basis of eliminating the yellow standard car, vigorously promote new energy vehicles. It is reported that next year, in the city public transport such as buses, taxis, and urban public services such as sanitation, logistics, airport commuting, and public security patrols, the proportion of new energy vehicles in new or updated vehicles will be no less than 30%. By 2016, the central government agencies and new energy vehicles purchased by government agencies and public institutions in the city of new energy vehicles will account for no less than 30% of the total number of vehicles equipped with newer vehicles, and will expand in size year after year.
At the same time, the government will accelerate the construction of new energy vehicle infrastructure. The requirements and proportions for building construction parking lots and urban public parking lots reserved for charging facilities are clarified, national unified national standards and industry standards for charging facilities are formulated, land use policies for charging facilities are improved, and electricity for electric vehicle charging facilities is fully utilized. Implementation of the supportive electricity price policy.
Improve the car's environmental management system
On the basis of accelerating the promotion of new energy vehicles and the elimination of yellow-label vehicles, the management of the future life of automobiles from production to use will also enter a new stage.
It is reported that the "Program" clearly defines the motor vehicle access permit and compulsory certification system, and establishes an integrated management mechanism for integrated production consistency inspection before the end of next year, and includes the key components of the exhaust gas treatment, "three-way catalytic converter", etc. For the scope of product certification (3C), vehicles that do not meet the national motor vehicle emission standards shall not be produced, sold or imported.
At the same time, it is necessary to improve the motor vehicle recall system by the end of 2016 and strengthen the requirements for environmental protection. If there are widespread non-compliance with relevant national emission standards in the same batch, model or category of motor vehicles due to design and manufacturing defects, production will be The company implements a recall.
In addition, the "Program" also pointed out that in 2016, key cities in the Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta regions will fully implement the fifth-stage gasoline and diesel vehicle emission standards. Starting in 2017, the newly produced low-speed trucks will implement the third-stage light-duty diesel vehicle emission standards.
Strengthen the importance of the public transport system
In addition to the management of the car, the "Program" also proposed the goal of urban traffic management. Among them, the "Program" pointed out that by 2015, the share of public transport motorized travel in Beijing and Shanghai's central urban areas will reach more than 60%; by 2017, the per capita public transport facilities in Beijing, Tianjin, Hebei, the Yangtze River Delta and the Pearl River Delta will have a higher level than 2012. The annual increase of 30% in urban areas and the urban population with a population of more than 1 million will reach about 60%. The sharing rate of walking and bicycle trips in megacities and big cities will increase by about 5 percentage points, and the sharing of bicycles and bicycles in small and medium-sized cities will be shared. The rate is increased by about 10 percentage points.
Moreover, it is necessary to actively promote trolleybuses, build a city mobility travel system based on urban public transportation, establish an effective urban comprehensive traffic management system, and increase the proportion of public transportation. At the same time, we will gradually improve the public transportation system with mega-city as the core. Areas with conditions actively promote trolleybuses, and promote community buses, bicycle rentals, and “P+R†(parking and transfer).
Poly Aluminium Chloride is referred to as PAC. It is also commonly called basic aluminum chloride or coagulant. It is a new type of high-efficiency inorganic polymer flocculant. Its aqueous solution is a hydrolysis product between aluminum trichloride and aluminum hydroxide, with a colloidal charge, so it has a strong adsorption on suspended matter in water. To achieve the purpose of condensing suspended matter in water. The Polyaluminium Chloride produced by Jinhe are white, yellow or light yellow powder.
Polyaluminum Chloride has the functions of removing suspended matter, COD and BOD, degreasing, decoloring, removing heavy metals and residual chlorine in water, etc. It is mainly used for purification treatment of tap water and industrial wastewater. Polyaluminum chloride is currently the most widely used inorganic coagulant in water purification processes. There is no need to adjust the pH value of the source water, it has a wide range of adaptation to the pH value of the source water, which is unmatched by traditional inorganic low molecular coagulants.
Polyaluminium Chloride is used in metallurgical, electric power, tanning, medicine, printing and dyeing, papermaking, chemical and other industries` sewage treatment.It`s also used in tap Water Treatment. Its coagulation effect forms flocs (also known as alum flowers) fast, the particles are large and heavy, and the sedimentation is fast. The applicable PH value ranges from 5 to 9, and has the characteristics of low dosage, low cost, high activity, convenient operation, wide adaptability, and low corrosion.
