Based on the prevention and control principles for water, air, solid waste, and physical pollution, discuss your understanding of these principles in light of practical situations.

The topic is a bit broad. To answer briefly: First, decision-makers need to raise their environmental awareness ； Secondly, it is necessary to use raw materials that generate less pollution; thirdly, advanced technical processes that produce little pollution should be employed; fourthly, efforts must be made to recycle and eliminate pollution (it is even better to turn waste into resources); fifthly, compensation must be provided for the pollution that cannot be recycled or treated at present.

Governance-------Every aspect of governance requires investment. It’s fine if you have the company’s management to cover the costs, but if those costs are high, who will be willing to invest? Each item should be technically feasible to manage properly; it’s just a matter of investment. Some people mention advanced technical processes, but those also require initial investment and further investment. Nowadays, many business leaders are only concerned with maintaining stability; how many patents are actually turned into practical applications each year? Some green technologies may also have no cost advantages. Achieving good environmental protection depends on the level of management in place. If it’s just a matter of imposing fines, small companies will pay some fines, and their product costs won’t increase much as a result. But for large companies, implementing environmental protection measures will certainly lead to higher costs. It’s not those who pollute that are responsible for cleaning it up; rather, it’s those who pollute who must shut down. Small businesses or those that lack the ability to innovate will close down, while those business owners who wish to continue operating their companies will inevitably increase their investments in developing new processes and improving management practices. In this way, costs rise while profits are maintained, and these increased costs are passed on to downstream companies; the higher product costs of those companies are then passed on to society. In the end, it should be the entrepreneurs who contribute to society (through taxes, employment, etc.), while the whole society bears the cost of dealing with the pollution. Maybe the consideration is too simplistic! !

Everyone has summarized this very well. I think the key to dealing with pollution lies in prevention; treatment serves as a supplementary measure, just like fire fighting – prevention is crucial, and a combination of prevention and treatment is essential! This kind of theoretical thinking is also very useful when applied to pollution control; yet in reality, the opposite happens – there is no emphasis on using such thinking to prevent problems, and a sense of complacency prevails. Instead, people wait until pollution occurs before thinking about how to prevent it. There are countless such examples. In my opinion, in reality, over 80% of safety incidents and pollution-related accidents occur because people try to fix things after the damage has already been done, resulting in losses in terms of production, environmental damage, and harm to human lives. The view expressed above is completely correct – it’s not the party that causes pollution that should be responsible for cleaning it up. If this way of thinking continues, our environment will eventually retaliate against us; in fact, it has already started to retaliate against humanity ； Think about it: the cancers that are common among people these days were virtually unheard of just a few decades ago, except among those who worked in certain industries. Now, contracting cancer has become as common as having a cold – it’s something that happens frequently. Even people living in remote areas with a favorable natural environment can suffer from this disease, which shows that there is a serious crisis in our environment ； This is just the case with cancer; the number of cases of other rare diseases has also increased significantly compared to before (CCTV once aired a program on this topic). The emergence of such strange and rare diseases has devastated many families, resulting in substantial losses to GDP in this area. This is the criticism stemming from pollution first. Regarding the environmental remediation process, in my opinion, it takes far more than a year or two to clean up an already polluted area; it may actually take hundreds of years. It’s not an exaggeration to say so! The costs associated with pollution control are astronomical. I came across a research report on the efforts to address water pollution in the Huai River basin; billions were invested over time, yet the water quality did not necessarily improve. What does this indicate? It shows that while pollution is easy to cause, it is difficult to eliminate. Pollution control is a complex process that involves various aspects, whereas our efforts to address it start from just one point alone, which highlights the enormity of this task! To be honest, the money that companies earn – if it leads to environmental damage – is simply not enough to cover the costs of remediation; such money is merely a drop in the bucket when it comes to addressing pollution! Fortunately, new environmental laws have now been enacted; fines are no longer minor amounts – there are now fines in the hundreds of millions, and even measures such as shutting down businesses ； In the face of environmental pollution, there are no exceptions – anyone who violates the rules will not be able to turn things around; they will have to pay the price for life. Only by raising the cost of breaking the law in this way can such violations be curbed ； To eliminate it, perhaps a process is still needed. What I have said above represents only my personal opinion; there are many instances where my words fail to convey the intended meaning, so I earnestly ask fellow netizens to point out any mistakes! I will share my understanding of pollution prevention and control when I have time later.

Good evening everyone: I have some time tonight and would like to continue discussing the topic raised by the original poster. I would like to build on my own personal experiences to continue discussing a specific topic—solid waste pollution in chemical plants. The prevention and control of solid waste pollution in chemical plants is a systematic task that involves a high degree of randomness! At the organization where I used to work, there was a centrifugation unit that produced calcium carbonate containing bacteria. In fact, the bacteria present in that calcium carbonate could have been recycled, but the organization simply didn’t pay any attention to such details. Some technical staff suggested implementing changes to recover those bacteria, but their suggestions weren’t given any consideration by the management, who had no understanding of biochemistry – perhaps they only knew the term itself, haha. As a result, those bacteria were discarded day after day, year after year. Of course, the bacterial cells do not contaminate the environment. What was discussed today is the fact that the calcium carbonate contained within is wasted in a regrettable way. The calcium carbonate waste resulting from centrifugation can be transformed into high-quality gypsum or plaster powder after simple treatment – namely by washing it with water. This by-product can thus be turned from waste into a valuable resource ； The company definitely has the capability to carry out this process. It’s a shame, however, that the company’s management is in a state of chaos, with senior managers scheming against each other. As a result, they have to pay high prices to hire outsiders to handle this task, and some people take bribes in exchange for their services. Since those outside can make a lot of money simply by transporting the calcium carbonate away, they don’t bother to find a proper way to utilize it; instead, they just find a place with no supervision, dig a hole, and dump the calcium carbonate there. Since this centrifuged calcium carbonate was separated in an acidic environment with a low pH value, the pits used for storing it grew larger and larger. Due to rainfall, the acidic rainwater in these pits gradually seeped into the ground over time, contaminating the local groundwater. As a result, the water consumed by the villagers living in the surrounding area had an acidic taste and was difficult to drink; consuming it could cause diarrhea and other problems. It was not until the environmental protection agency discovered this source of pollution that things were addressed. You can see how serious the problems that arise from corporate management are – pollution is hard to prevent, and dealing with it is indeed a real headache! Don’t forget that the Earth is a single ecosystem; once it’s polluted, no one can stay untouched!

First is source control: advanced process improvements, new treatment technologies, and equipment innovations. Next is monitoring during the intermediate stages, and finally finding the most suitable methods for final treatment
