Each patch presents one viewpoint (related to wastewater treatment, solid waste treatment, or exhaust gas treatment). The viewpoint should be clear and concise. Reward: 1 lucky winner will be selected from floors 2 to 100, receiving 100 wealth as a prize. From 101 to 1000, 1 lucky winner will be selected and awarded 500 wealth points. Penalty: Simply copying someone else’s post results in an immediate -100 to wealth points once detected. Watering carelessly will result in an immediate -100 wealth penalty once discovered. Example post: Biological methods (or biochemical methods) are widely used processes in wastewater treatment today, encompassing various different techniques, and are primarily applied in the secondary and advanced treatment of wastewater.
Ha, let’s grab a sofa: The recycling method involves reusing the waste gases generated during the manufacturing process. This serves two purposes: it reduces production costs and ensures that the exhaust gases are discharged in compliance with regulations. In our previous manufacturing process, ammonium bisulfite was used, which produced large amounts of sulfur dioxide; by using ammonia water to treat these exhaust gases, ammonium bisulfite or ammonium sulfite was formed, achieving two goals at once, ha
It is time to pay attention to solid waste management, issues such as cities surrounded by garbage, and soil pollution. One is to recycle resources, and the other is to restore ecosystems; these need to be done as soon as possible
In biological treatment methods for wastewater treatment, depending on the microorganisms involved, biological treatment can be divided into two types: aerobic biological treatment and anaerobic biological treatment.
There are various methods for flue gas desulfurization in power plants, such as the gypsum method, the magnesium oxide method, and the ammonia method. Among these, methods like the gypsum method are considered disposal-based approaches, as the calcium sulfate gypsum produced as a result of desulfurization is essentially discarded, leading to large amounts of gypsum accumulation. Due to the maturity of this technology and its low cost, it is widely used; in my opinion, this method is suitable for situations where the flue gas flow rate is high but the SO2 concentration in the flue gas is low； However, in cases where the flue gas flow rate is not very high, especially when the SO2 concentration in the flue gas is high, it is recommended to consider the recovery method more seriously. In this approach, SO2 in the flue gas is not treated merely as a pollutant, but rather as a sulfur resource that can be recovered. For example, ammonia-based desulfurization can be used to produce sulfuric acid, which can then be used as a sulfur-containing fertilizer. Given the current high prices of sulfur and the increasing scarcity of this resource, the recovery method remains a viable technical approach worth considering. Regardless of the desulfurization method used, it is necessary to take into account the specific conditions of each plant, as well as the international and domestic landscape, and to balance short-term and long-term interests in order to achieve a combination of social benefits and environmental benefits.
Concentrate the waste liquid using triple-effect evaporation. . . .
Solid waste is treated at high temperatures using plasma (referred to as ‘plasma’ in Taiwan, China). Using this process, organic materials are gasified into combustible gases composed of carbon monoxide and hydrogen, inorganic materials are vitrified to form building materials, and metals are recycled.
How to choose zero-emission technology solutions
The more established solid waste treatment methods in China include sanitary landfilling and composting. Composting is the process of using microorganisms to break down organic waste and convert it into fertilizer. Sanitary landfilling is a method of solid waste disposal that incorporates environmental protection measures such as leak prevention, compaction, covering, and treatment of gases and leachate.
Waste treatment essentially involves transforming waste from one form into another. Treating wastewater generates solid and gaseous waste; treating gaseous waste produces liquid and solid waste; and treating liquid waste yields solid and gaseous waste, haha.
To this day, it still seems that there are no effective methods for sewage treatment in our country, and the same is true for solid waste – the only options are landfilling or incineration, with little use being made of sorting. This is related to our technical level as well as the quality of the general public; is waste sorting really that difficult? I think as long as no one is able to exercise self-discipline in educating the next generation from an early age, things might get better by the time our descendants grow up. However, water pollution remains severe; I wonder if the equipment needed to treat wastewater is too expensive, thereby placing a heavy burden on businesses Apart from some state-owned enterprises that install such equipment, other companies would rather bribe the safety supervision agency than install it; really, there’s nothing to say about that.
