From traditional sewage treatment plants of reinforced concrete structures to sewage treatment plants of prefabricated construction, a revolutionary innovation is happening in the environment industry.

Automatic production line of the three-way segregation system by PK Environment

At the prefabricated sewage treatment plant "PK Round", Yangcheng Evening News saw that sewage continuously enters the plant's prefabricated sewage treatment system. This municipal sewage, such as wastewater from residents' bathrooms and kitchens, is transformed into up-to-standard discharge after undergoing a series of physical and biological treatments at the sewage treatment plant.

Compared with traditional sewage treatment plants, "PK Round" has comprehensive advantages such as smaller space, lower investment, shorter construction period, and smarter operation. Its prefabricated construction has achieved automated production at PK Environment's Environmental Intelligent Industry 4.0 Production Base in Zhaoqing.

In the production base, on the automatic production line of the three-way segregation system) independently developed and designed by PK Environment Technology Corp, the sheet is transported to the feeding spot, the transfer positioning table, etc. The intermediate processes, such as bending machines and mechanical welding, are all fully automated.

In the control interface of the "Digital Operation Management Platform" independently developed by PK Environment, the water volume section and the water compliance rate section present the monthly sewage treatment situation of the operation sites digitally with graphics. In the cost analysis section, the costs of sludge disposal, labor, electricity, and other expenses are displayed in a curve form, making it clear to see the changes in costs every month.

A staff of PK Environmental demonstrated the "PK Round Intelligent Plan Platform" to Yangcheng Evening News and said, "If the scale of this municipal sewage treatment plant project is 15,000 tons, this system can automatically generate a design plan of dozens of pages through intelligent calculations according to basic project information such as filling capacity, temperature, and water quality of the inlet and outlet water." In the plan automatically generated in less than three minutes, the project overview, design basis, process selection, process flow, and preliminary design drawings were available.

"PK Environment's digital construction is no longer simply digitizing a certain sector but the whole process from design to production, operation, and enterprise management." The chairman of PK Environment told Yangcheng Evening News that compared with the development of automation, digitization and intelligence in the automobile, furniture and other industries, those in the environment industry are not advanced. He wants to realize intelligent design and intelligent production through cross-border comparison like Shangping Zhaipei, a furniture customization platform, where furniture will be automatically produced at the factory after the design drawings are completed at their stores.

一家污水处理厂的数智进化

从传统的钢筋混凝土结构污水处理厂，到在工厂预制模块化装配式结构的污水处理厂，环保行业的“建造”颠覆故事正在发生。　　

羊城晚报记者在装配式污水处理厂“鹏凯圆”看到，污水源源不断地进入厂区装配式污水处理系统，这些来自居民住户的卫生间、厨房等的城市生活污水，经过污水处理厂进行系列物理、生物处理后，污水变为达标排放的清水。

与传统的污水处理厂相比，“鹏凯圆”具备占地更小、投资更省、建设周期更短、运行更加智能等综合优势，而它的预制装配式结构则在肇庆的鹏凯环境智慧化工业4.0生产基地实现了自动化的生产。

在生产基地里，由鹏凯环境自主研发设计的三相分离器自动生产线上，板材运输至上料工位、中转定位台等，中间经由的折弯机、机械焊接等工序均实现全自动。

在鹏凯环境自主研发的“运营数字化管理平台”中控界面，记者看到水量板块、水量达标率板块用数字、图表形象化地呈现了运营站点每个月的处理水情况，成本分析板块里污泥处置费、人工费、电费等费用则是通过曲线形式展示出来，可以很清楚地看到每个月的成本变化情况。 

“如果这个生活污水处理厂项目的规模是15000吨，填水量、温度、进出水水质等基本项目信息，就可以通过智慧运算自动生成一份数十页的设计方案。”鹏凯环境工作人员向记者演示“鹏凯源智慧方案平台”，在短短不到三分钟时间就自动生成的方案里，项目概况、设计依据、工艺比选、工艺流程、初步设计图等一应俱全。

“鹏凯环境如今的数字化建设不再是简单地对某一个板块做数字化（改造），而是从设计到生产、运营、企业管理的全流程数字化。”鹏凯环境董事长告诉记者，对标汽车、家具等行业的自动化、数字化、智能化的发展，整个环保行业说不上先进，他想通过跨界对标来实现智慧设计到智慧生产的联动，甚至像商品宅配一样，在店面设计好图纸、到工厂就自动生产。
