As the manager of Blue Star Environmental Engineering Company spoke with confidence and simply discourse, Guo Youzhi, deputy director of the Ministry of Science and Technology and vice chairman of the China Film Industry Association, did not hesitate to lift the glass and openly savored it. The Assistant General Manager of Tianjin Petrochemical Company also raised it. The cup...
The petrochemical wastewater treatment plant of the Tianjin Petrochemical Sewage Treatment Plant witnessed a lively rejoicing.
This is February 27 this year, the company's Ministry of Science and Technology related personnel in the investigation of Tianjin Petrochemical oily wastewater treatment and water reuse project occurred at the scene of the scene.
Drinking plain ordinary drinking water can cause cheers that make people uninformed. However, the rich commentators behind this cup of clear water will use cheers to express their feelings at this moment.
Everyone in the scene saw it with his own eyes: a pool of oil whistling, swarthy, dirty and pungent refinery waste water, after several “slots and tanks†process, it turned magically into crystal clear water, if not The on-site staff publicly poured a glass of clear water from the clear water flowing from the experimental device. Everyone really could not associate the fresh water in the cup with the bizarre process of transfiguration.
The cheers have multiple meanings. The test results show that the test work of the zero emission pilot project of the group company has achieved satisfactory results.
From the fourth quarter of last year, the group started brewing and deploying energy-saving and emission-reduction targets with “zero emissions†as its goal. At the beginning of October, the relevant departments organized a “zero emission†comprehensive survey; immediately afterwards, pilot projects, pilot units, and technical programs were successively confirmed. At the end of December, industry experts reviewed and passed a pilot project for the implementation of a zero-emission project for wastewater treatment by China National Chemical Industry – the technical plan for the reuse of refinery wastewater and the treatment of PVC centrifuged mother liquor.
At the end of the year, the test work of Siping Haohua Chemical Co., Ltd. and Lanxing Petrochemical Tianjin Branch began quietly. Hangzhou Water Treatment Technology Center and Blue Star Environmental Engineering Co. (formerly Blue Star Water Treatment Company) respectively performed technical research on two pilot projects. In the past two months, the test of Tianjin Petrochemical's refinery wastewater treatment has been running for nearly 40 days. The experimental treatment of the PVC centrifuge mother liquor by Siping Haohua is also in progress. On February 27, the Ministry of Science and Technology of the Group Corporation went to Tianjin Petrochemical to inspect the progress of the experiment. The results of the advanced treatment experiment for refinery wastewater are encouraging. The head of the Ministry of Science and Technology is drinking the refinery wastewater transformed into clear water on the spot.
The exploration of domestic refinery wastewater reuse began in the 1970s, but there has been no effective breakthrough. At present, due to the increasingly prominent water shortage in China, the research and application of wastewater reuse has become increasingly widespread. Advanced treatment and reuse of refinery wastewater is an innovative and significant topic in the industry. In the integration of a reasonable pretreatment process, membrane material selection, membrane flux setting, membrane fouling, membrane cleaning recovery, continuous operation, and improved domestic production A series of technical problems, such as the rate of reduction, the reduction of costs, and the realization of engineering, have yet to be explored. The technical personnel of the Tianjin project, the technical personnel of Lanxing Environmental Engineering Company, carried out close technical cooperation with Tianjin Petrochemical and carried out a series of research work. The company independently developed a mobile double membrane experimental device and passed the physical pollution-resistant membrane. The treatment technology combines chemical treatment and biological treatment technologies to achieve the reprocessing of contaminated water, and responds to changes in water quality and water quality through the combination of changes in parameters and modules to obtain a more adaptable treatment process technology.
The ultimate goal of refining waste water through technical treatment and turning waste into treasure is not drinking. The actions of drinking water by technicians and project team technicians only represent the confidence of this advanced treatment process. They said: It is not difficult for the wastewater to become clear at the current state of the art. Here, a glass of clear water can only represent the starting point for the promotion of zero-emissions management, followed by a lot of hard and meticulous work to do.
The person in charge of Lanxing Environmental Engineering Company stressed that with membrane integration technology as the core, optimizing the process, minimizing the cost of water production, and effectively realizing the industrialized application value of refinery wastewater, it is a significant event and the largest innovation. Industrialization is a real challenge.
On the 27th, all parties conducted a relatively full technical exchange at the site, but the core of the exchange was not at the experimental link. The scientific research management department, the water treatment engineering technology department, and the pilot units had their eyes fixed on the operating production system. It is also at the source of governance. Blue Star Environmental Engineering's technical experts proposed several issues that must be addressed, including the transformation of the original three-stage wastewater treatment plant and the improvement of some of its production processes. Experts even suggested that a detailed and scientific analysis of the operation of the company’s existing installations should be conducted to study the process route, confirm technological loopholes, find management defects, find some key nodes, identify the waste water composition, truly realize clean production, and promote site management. And process management to a new level.
The expert's proposal was positively affirmed by the members of the leadership team of Tianjin Petrochemical. In their opinion, Tianjin Petrochemical is not only optimistic about the economic “money†scenario where waste water can be reused to make a few cents per ton of water. As the “zero emission first test†bearing unit, it is more optimistic to become the benchmark for energy-saving and emission reduction in the industry. It is a big prospect. Tianjin Petrochemical will use pilot projects to continuously improve the production process management and improve basic management and process control as the focus of the company's work in the coming period. The upcoming major overhaul work is a good time to “check for shortages and make up for leaks†and to industrialize the reuse of waste water for reuse. Enterprises will spare no effort to support energy conservation and emission reduction work.
The preliminary practice of zero-emissions management work actually highlights the core issues of energy-saving and emission reduction in front of enterprises. The current technology can realize turning waste into treasure, but the most critical thing is to strive to achieve the goal of “controlling the discharge of waste in the production process until it reaches zeroâ€. Governance, optimization of processes, improvement of management, and reduction of emissions from the source are major prerequisites for zero-emissions management.
"This cup of water can drink!"
