Abstract: Chemical industrial parks are closely linked to urban economies. Frequent occurrences of accidents in domestic chemical industrial parks have caused severe economic losses. With the Chinese government imposing increasingly stringent accident prevention requirements, the construction of public emergency lagoon systems has become critical to ensuring safe production in chemical industrial parks. ?This paper summarizes the construction landscape and fundamental requirements for public emergency lagoon systems in China's chemical industrial parks. It also explores the design methodology and key considerations? of such systems through a case study of the public emergency lagoon project in Quanhui Petrochemical Industrial Zone.

Key words: public emergency lagoon, chemical industrial park, safety in production, environmental accident
