Chapter 3570

On this day, Su Xinghui came to Tongfu Environmental Protection Technology Co., Ltd. again. He came, of course, to check on the results of Tongfu Environmental Protection Technology Company's treatment of heavy metal-polluted land.

Ever since Guan Tongfu founded this Tongfu Environmental Protection Technology Co., Ltd. here, Su Xinghui would come to their company at least once every year to see their results, because the hundreds of thousands of mu of heavy metal-polluted land in Baozhou City had always been a source of anxiety for Su Xinghui.

Arriving at Tongfu Environmental Protection Technology Co., Ltd., Guan Tongfu was already waiting for Su Xinghui at the company entrance. The current Guan Tongfu had a much steadier temperament than when Su Xinghui first met him a few years ago. Seeing Su Xinghui get out of the car, he hurriedly came forward to greet him, saying, "Mayor Su, hello!"

Su Xinghui shook hands with Guan Tongfu and said, "General Manager Guan, hello! I have come to your company again today."

Guan Tongfu said, "It is our company's honor that Mayor Su can come over. All our employees warmly welcome you!"

Su Xinghui laughed and then entered the company with Guan Tongfu. Compared to the start-up period, the current Tongfu Environmental Protection Technology Co., Ltd. had undergone great changes. Now their area had expanded, and incinerators and equipment for extracting tailings had all increased, which gave them even greater processing capacity.

Now, it was not just Baozhou City's tailings that were handed over to Tongfu Environmental Protection Technology Co., Ltd. for processing; mines in the surrounding cities also mostly handed their tailings over to Tongfu Environmental Protection Technology Co., Ltd. for processing.

At the company entrance, Su Xinghui saw a large number of trucks loaded with tailings waiting to unload, while a large number of trucks loaded with that kind of pressed brick were driving out of the company gate.

One of the main businesses of Tongfu Environmental Protection Technology Co., Ltd. was to re-press the tailings after extracting heavy metals into that kind of eco-friendly brick and sell them. This was a method of waste utilization, but of course, its more important role was to ensure that these tailings no longer occupied large areas of open land.

The indicators such as the strength of these bricks were no lower than traditionally fired red bricks, and they could be used as building materials. In Baozhou City, the construction bricks currently used were basically this kind of brick, which could save farmland, because the firing of red bricks required taking soil from farmland, which caused significant damage to the farmland.

Of course, relying solely on the bricks produced by Tongfu Environmental Protection Technology Co., Ltd. was not enough, so the byproduct stone powder from Baozhou City's quarries had now also become a treasure. Many manufacturers producing this kind of pressed brick would haul this kind of stone powder to their own factories to press into bricks.

The tailings processed by Tongfu Environmental Protection Technology Co., Ltd. had main components that were about the same as those stone powders.

Su Xinghui said, "General Manager Guan, business is booming for the company now!"

Guan Tongfu said, "It's not bad. Now the company's tailings processing capacity has been greatly strengthened. Basically, as long as the tailings are sent over, they can all be processed. These pressed bricks are now also one of the company's main sources of operating income."

Guan Tongfu took Su Xinghui to look at the company's tailings processing equipment and then went to look at the incinerators.

The incinerators burned the plants grown on land severely polluted by heavy metals. These plants absorbed the heavy metals, and after incineration, the heavy metals remained in the waste residue after burning. After extraction, they became pure heavy metals, which could be utilized.

Through this cycle, the heavy metal content in the land where these plants were grown would become lower and lower until it fell below the minimum standard stipulated by the state, at which point crops could be grown. Only then could these lands be considered successfully restored and treated.

Tongfu Environmental Protection Technology Co., Ltd.'s processing of tailings was to prevent the heavy metal content in these lands from continuing to rise, while planting plants to absorb heavy metals could gradually reduce the heavy metal content in the land, so this was a very scientific and reasonable path of treatment.

Although this treatment method required too much time—at least ten years or more—to finally achieve the goal of restoration, it was still better than completely abandoning these hundreds of thousands of mu of land.

If these hundreds of thousands of mu of land were completely abandoned, there would be a risk of expanding pollution, because if it rained, the heavy metals on these lands would be carried to other lands, causing the pollution to spread further. Therefore, no matter what, these lands had to be completely restored; otherwise, it would affect future generations.

The incinerators of Tongfu Environmental Protection Technology Co., Ltd. were all specially made and fully enclosed. The flue gas produced by incineration was also treated through environmental protection equipment and was completely harmless before being discharged. All of this had passed environmental impact assessment tests.

While watching these processing equipment and incinerators at work, Su Xinghui asked Guan Tongfu about some technical indicators. After listening to Guan Tongfu, he was very satisfied with the processing efficiency of Tongfu Environmental Protection Technology Co., Ltd.

Now Tongfu Environmental Protection Technology Co., Ltd. was investing in more and more equipment, and it was becoming more and more advanced, so their processing efficiency was also becoming higher and higher.

After seeing the equipment in the company, Guan Tongfu took Su Xinghui to several sites for the restoration and treatment of heavy metal-polluted soil. This was also the most important part of Tongfu Environmental Protection Technology Co., Ltd.'s business. Every year, the Baozhou Municipal Government would send special personnel to strictly test the heavy metal content in these restored lands to keep track of the effects of the restoration and treatment at any time.

Su Xinghui was also very concerned about these test results. He would look at these test results every year, and the results were also very gratifying to him. The heavy metal content in these lands was decreasing year by year. At this rate, in about twelve to thirteen years, the heavy metal content of these lands would be able to meet national standards, and they could start growing crops again.

This speed was already considered relatively fast, but twelve to thirteen years was still a very long time, which made Su Xinghui sigh with emotion. Whenever he thought of those mine owners who destroyed these lands, he couldn't help but feel indignant. For their own selfish desires, they committed such crimes; it was truly unforgivable.

Fortunately, those mine owners represented by Zhang Dacheng would still be in prison for a long time and would pay the price for their sins.

On these lands, lush plants were growing. These plants were growing very well on these lands. I don't know if it was because the heavy metal content in these lands was rich, which instead nourished these plants that liked heavy metals, making them extra green and robust.

Guan Tongfu had not been idle these past few years. He had found several more plants that had special effects on certain heavy metals and had also planted them on these lands. In this way, their efficiency in absorbing heavy metals had increased again.
