Various wastewaters are generated during the production process of the enterprise, such as: desulfurization wastewater, reverse osmosis concentrated brine, acid stripping water, boiler sewage, circulating water system sewage, electrical desalination sewage, other production process wastewater, such as: coking wastewater, biopharmaceutical wastewater, etc. The existing environmental protection requirements are that all enterprises' wastewater must meet discharge standards. How to deal with the above-mentioned wastewater has become a problem that each enterprise must solve. Most of the existing domestic wastewater treatment technology routes treat wastewater and then discharge it to meet standards. Some and a few companies have also tried to treat wastewater with zero discharge, but they have been discouraged due to reasons such as "high investment, high operating costs, high energy consumption" and other reasons. Stop. Therefore, zero wastewater discharge has been unable to be implemented and promoted in our country. Qingzhou Xinlu Energy Saving Technology Co., Ltd., in conjunction with the National Laboratory of Pollutant Emission Reduction of Shandong University, combined the strengths of multiple technologies, avoided their weaknesses, and found a new approach to develop an economical and practical zero-discharge technology for wastewater that is suitable for China's national conditions - "Chemical Wastewater Zero Discharge" "Emission complete set of technology" has been actually operated by multiple users, and all indicators have met the design requirements, and has been affirmed and accepted by experts and users. This technology has the characteristics of low investment cost, simple process technology, high wastewater utilization rate, and safe equipment operation. It can be widely used in high water-consuming industries such as petrochemical, steel, power generation, coal, chemical and pharmaceutical industries. Through long-term exploration and practice, Qingzhou Xinlu Energy Saving Technology Co., Ltd. has discovered that the current national circulating water management standard "Industrial Circulating Cooling Water Treatment Design Specification" B has many practical problems. If the circulating water system is managed according to the current standards, system scaling will still occur. and corrosion, and a large waste of water, which has lagged behind the development of the times. In line with the spirit of seeking truth from facts, bold innovation and the courage to make breakthroughs, Xinlv Company has creatively proposed a circulating water system after four years of research and thousands of tests and practices. New management theories and new methods, and the successful development of high-efficiency water treatment agents suitable for my country's existing water quality conditions. Industrial applications have proven that this method is feasible and effective, and the high-efficiency agents can fully meet my country's existing water quality needs. On the basis of the above, Qingzhou Xinlu Company creatively proposed the concepts of "zero discharge of circulating water system" and "zero discharge of wastewater using circulating water system". After countless studies and tests, it finally completed these two major projects. Development of revolutionary technologies. And through the industrial application of many enterprises, so far, it has successfully achieved zero discharge of refining wastewater, zero discharge of coking wastewater from coking plants, zero discharge of biological wastewater from biopharmaceutical plants, zero discharge of reverse osmosis concentrated water from thermal power plants and zero discharge of acid-base ion wastewater. These projects, including zero-discharge metallurgical wastewater from desulfurization wastewater in the boiler industry and zero-discharge urban gray water, have been running well so far. Qingzhou Xinlv Company's products and technologies have completely subverted the existing management methods and models of circulating water systems. It creatively opens up a new direction and approach to wastewater treatment. Compared with other wastewater treatment processes and technologies, in terms of comprehensive utilization of wastewater, it has the characteristics of low investment cost, simple process technology, high wastewater utilization rate, and safe equipment operation. Its emergence will surely provide powerful measures and technical guarantee for my country's environmental protection, energy conservation and emission reduction. A technical route. Due to the needs of the production process, many companies are equipped with circulating cooling water systems of various sizes. The circulating water system is generally composed of cooling tower water pump production equipment (such as heat exchangers). Due to the operation of the circulating water system It is characterized by long-term continuous operation, so the cooling tower fan also works continuously, resulting in a large amount of water evaporation. In order to ensure the normal use of the system, it is necessary to continuously replenish new water sources to the system. "Chemical wastewater zero discharge technology" is to make full use of the characteristics of the circulating water system that requires continuous replenishment of water, using various corporate wastewater as supplementary water and adding our company's special chemicals into the circulating water system. Under the action of chemicals, the harmful properties of harmful substances in wastewater are suppressed. These harmful ingredients eventually precipitate into water slag due to super saturation, and are separated from the circulating water system through sedimentation or bypass filtration systems, thereby ensuring the long-term safety of the circulating water system equipment. No scaling and no corrosion. Zero discharge of enterprise wastewater can be achieved by ensuring that the circulating water system does not discharge sewage or that the sewage is returned to the circulating water system after settling. "Chemical wastewater zero discharge technology" makes full use of the company's wastewater resources and reuses the wastewater that the company originally spent money to treat and discharge, saving the company's water resources fees, wastewater treatment fees, sewage discharge fees and other expenses, which is the company's It brings economic benefits and can fundamentally solve the pollution of water resources and environment caused by wastewater discharge.
