Individual water plants use this should eliminate waste barrels, drinking barrel life is only three years

Use waste plastics, old CDs, or even foreign waste to make potable water? The "black heart barrel" incident that was exposed in Shandong a few days ago makes people feel shocking. Is there a "black heart barrel" in our city? Yesterday, the reporter conducted a survey and found that most people knew little about the knowledge related to drinking water barrels. The buckets are "out of service" and are used for as long as five or six years.

I don't care about the water supply point from the waterworks rental bucket. "The black bucket should be the "black heart bucket." In fact, I don't know for myself." Yesterday, the public Miss Zhou told reporters. She said that at home she drinks a large bucket of bottled water almost every week. She never cares about the color of the barrel wall when she comes.

Ms. Huang told reporters that each time she sends water, she must observe whether the water quality is clear and there is not much concern for the bucket itself.

"We don't buy buckets for water, but sometimes the public or the waste collection also sells us some buckets." Yesterday, at a water supply point in Jiangbei, a water worker quietly told reporters. He said that they generally buy buckets to see if there is any leakage. As for the barrel wall is not dark, the barrel inside is not clean, they do not care, just wash it on the line.

In the Yuzhong District, a staff member of the water supply station told the reporter that the buckets were all rented from the water plant. They only managed to leak the buckets and did not care what the material was. When the reporter saw the corner of the store, there were also several buckets with gray walls.

Plastics will have an ageing bucket life of three years, "a pot of drinking water, life is generally three years, will be eliminated after three years." Yesterday, Angel bottled water charge Xiong Daifu told reporters. He revealed that after three years, regular water plants will return water buckets to upstream manufacturers in exchange for new ones.

The person in charge of the Chongqing Food Industry Association barrel (bottle) filled drinking water section reminded that the industry's use of water barrels for three years is a threshold. However, due to cost considerations, individual water plants in the city have been using large amounts of waste barrels that should be eliminated. Such barrels are often prone to bacterial growth and cause new pollution in bottled water. In addition, plastics will naturally age after prolonged use, resulting in low molecular weight compounds. These substances dissolve into water and cause harm to humans after drinking. At the same time, some pigments, industrial preparations, etc. will also dissolve into water. In addition, the use of buckets for a long period of time may result in uneven barrel openings, resulting in tight seals and easily causing excessive microbial indicators.

Xie Yongqi, manager of the freezing point water sales department, reminded the public that if they find that their buckets have been “overdue”, they can ask the manufacturers to return them.

Bucket is divided into four kinds of new and old materials cost difference is "If you use a brand new PC to make buckets, and waste plastics to do, the cost difference at least two times." Yesterday, Chongqing Donghua Plastic Products Co., Ltd. Zhang told reporters, There are four types of pots for drinking water: food-grade new materials PC (scientific name polycarbonate) barrels, non-food grade PC barrels, PET (scientific name polyethylene terephthalate) barrels, and waste plastics, poor quality waste , Black discs made from discarded discs or even foreign waste.

Another general manager of Mingchuang Plastic Products Co., Ltd. also revealed that the food-grade PC (polycarbonate) is the best material for manufacturing drinking water barrels. The raw materials are almost all imported, and the amount of waste is over 27,000 yuan per ton. The price of medical waste is only 67,000 yuan per ton. According to an ordinary barrel with 0.8 kilograms of raw materials, the cost of regular raw materials is at least 26 yuan, and the market price of barrels sold to water plants is about 28-30 yuan. The buckets made of waste plastics have the highest market price due to their low cost. Also 15 yuan.

The difference between the old and the new depends on the production date at the bottom of the barrel. The person in charge of the Barrel (bottle) Drinking Water Branch of the Chongqing Food Industry Association told reporters yesterday that starting from October 2008, PET buckets that are not suitable for circulating purified water have been banned from use by the state. .

He said that people buy bottled water is best to use the brand through the QS certification, qualified barrel bottom marked with the name of the manufacturer and signs, material number, production date. “The identification of old barrels and new barrels also has a few tricks. The new barrel barrels are highly transparent, colored in blue or white, smooth and speckled, and rarely blisters in the barrels. Old barrels are generally darker in color or even black, with no transparency. There are black spots on the wall."

There will be two small circles at the bottom of the bucket. One of the circles is engraved with 1-12 digits. There is an arrow in the circle. There are also 09 and 10 words in the inner circle. This is the date of birth of the bucket. 09 means production in 2009, and the arrow points to the position. Represents the month of production; another circle is engraved with 1-30 numbers, and the arrow points to birthday.
