What environmental protection measures are required when constructing a large-scale sand and gravel production line?

When constructing a large-scale sand and aggregate production line, careful consideration must be given to protecting the surrounding environment. This is addressed through the following key aspects:

**Dust Control Measures**

To effectively control dust emissions, dust generation must be actively managed throughout the entire aggregate production process. The following measures can be implemented during the design phase:

1.  **Minimize Dust-Generating Stages:** In the process design, stages prone to generating dust should be minimized whenever possible. For instance, during aggregate screening, crushing, and conveying operations, efforts should be made to reduce dust generation to the greatest extent.

2.  **Select Low-Dust Equipment:** When selecting machinery, priority should be given to equipment models that generate less dust. This helps reduce both the generation and subsequent emission of dust particles.

3.  **Utilize Well-Sealed Conveying and Feeding Equipment:** For operations involving the transport of aggregates, conveying equipment with excellent sealing capabilities should be employed. This prevents dust from escaping and dispersing during the transportation process.

4.  **Optimize Chute Design:** When designing the chutes connecting various pieces of equipment, factors such as chute shape and angle must be carefully considered. Through rational chute design, the vertical drop of the aggregates can be minimized, thereby reducing the dust generated by high-impact drops.

**Noise Control**

To control noise levels, we can begin by focusing on equipment selection. First, we should prioritize the selection of equipment that inherently generates lower noise levels. Such equipment contributes significantly to lowering the overall noise level of the entire production system. Furthermore, for equipment that generates higher noise levels, we can house them within an enclosed facility or workshop. This enclosed environment effectively dampens the propagation of noise, thereby further minimizing its impact on the surrounding environment.

**Wastewater Treatment**

Domestic sewage undergoes preliminary treatment in a septic tank; it is then utilized for purposes such as landscaping and agricultural irrigation, rather than being discharged externally. Water used for spray-based dust suppression is considered "consumptive water," as it naturally evaporates during the dust control process.
