Slag handling refers to the process of managing and disposing of slag, which is a byproduct of various industrial processes, particularly in the metal and mining industries. Slag is a form of waste material that is produced when certain materials, such as iron ore, coke, and limestone, are melted and processed.

Effective slag handling is important for the proper management and disposal of this waste material. It helps to ensure the safety of workers, protect the environment, and maximize the potential value of slag through recycling and reuse.
Discussion on the setting of water pump room
[Abstract] This paper discusses the key considerations in setting up water pump rooms, focusing on the differences between separate and centralized pump room configurations within buildings. In water supply and drainage design, it is common to decide whether to locate the pump room inside or outside the building, and whether to establish a separate or centralized system. Properly designed pump rooms not only enhance building quality but also reduce capital investment and long-term maintenance costs. The following sections explore two main scenarios: the setup of separate pump rooms and centralized pump rooms, highlighting important issues to consider.
When setting up a separate pump room in a single building, it is typically located at the bottom, which is the most cost-effective option due to shorter pipelines and minimal impact. However, pump noise can cause disturbances, leading to complaints from residents. Although Shanghai’s "Residential Design Standards" (DGJ08-20-2001) Article 6.1.7 states that pump houses should not be located in residential buildings, there are exceptions. For example, in mixed-use buildings where commercial spaces are on lower floors and residences above, the pump room's noise has less impact due to the separation. Similarly, in high-rise buildings, pumps can be placed underground or within the building using silent submersible pumps, reducing noise disturbance. However, each approach has its own challenges, such as increased construction costs or compliance with regulations.
For centralized pump rooms, especially in multi-building complexes, they offer economic benefits by reducing equipment and management costs. According to DGJ08-94-2001, the service radius of a centralized pump room should not exceed 150 meters, and the pressure should be limited to 0.45 MPa. In practice, this requires flexible planning based on site conditions. In large industrial or residential areas, placing the pump room in an underground garage is often more efficient due to available space and reduced interference with other systems. Additionally, local regulations, such as those in Shanghai, require no sewage pipes inside the pump room and no pollutants near the water tank, further influencing the placement of centralized systems.
In high-rise residential areas, if basements are not connected, centralized pump rooms may not be suitable due to high-pressure requirements and complex pipeline layouts. However, when basements are interconnected, a centralized system becomes more practical, as internal pipelines are easier to maintain. Based on operational experience, it is advisable to plan for basement connectivity in high-rise developments to facilitate efficient water supply systems.
In conclusion, the design of water pump rooms is a critical aspect of water supply and drainage engineering. During the construction phase, water supply and drainage professionals should be involved early to explore various options. As the design progresses, coordination with local utilities and building professionals ensures the most economical and practical solution is implemented.
