From which aspects can wastewater reduction in factories be achieved?

In what ways can wastewater generation in factories be reduced, and how can efforts be made to save resources?
Zero discharge is achieved for circulating water, with all wastewater being used as make-up water for the circulating system

Rainwater collection in the tank area; after analysis, it is determined whether to discharge it into the sewage or rainwater system based on the results of that analysis. 3. The equipment rinsing water is reused in the process. 4. Eliminate leaks and reduce the use of flushing water.
Steam condensate and similar substances are incorporated into the circulating water system, enabling zero-pollution liquid discharge. Excess water from the circulating water is used as reclaimed water; after treatment, domestic wastewater is either returned to the circulating water system or utilized as reclaimed water. The most important aspect is water conservation
Is it feasible to use treated domestic wastewater for landscaping? I was worried about the smell, so I didn’t dare to use it.
I feel that ultimately, it should be process improvements to reduce water usage.
Wastewater must first not exceed **the standards**, and secondly, it is necessary to ensure that it does not cause pollution to the environment. Third is to advance new technologies
The situation varies from factory to factory; first, it is necessary to identify the sources of water usage, and then apply the value stream approach to address each issue one by one, analyzing various water consumptions and determining whether the water can be reused.
1. Process: Reduce water consumption and increase water reuse from a process perspective； 2. Production: Reduce spraying; collect the spray water; minimize direct discharge and recycle the collected water; try to avoid using water for cleaning. Use rags and mops frequently ； 3. Equipment: Cooling water circulation to reduce direct discharge and minimize leaks.
Reusing wastewater can reduce a certain amount
It depends on what kind of factory it is; after biochemical treatment, domestic wastewater basically has no odor
