Product introduction

Desalination is the production of fresh water by desalting seawater. It is an open source incremental technology to realize the utilization of water resources, which can increase the total amount of fresh water, and is not affected by time, space and climate. It has good water quality and reasonable price, and can ensure stable water supply for coastal residents and industrial boilers. The process of obtaining fresh water from seawater is called desalination. At present, the seawater desalination methods used are freezing method, electrodialysis method, distillation method, reverse osmosis method, and the reverse osmosis method using reverse osmosis membrane rapidly occupies the market with its advantages of simple equipment, easy maintenance and modular equipment, and gradually replaces the distillation method to become the most widely used method.

Seawater reverse osmosis, also known as ultrafiltration, is a membrane separation desalination method that was only adopted in 1953. Seawater and fresh water are separated by a semi-permeable membrane that allows only the solvent to pass through, but not the solute. The biggest advantage of reverse osmosis is that it saves energy. Its energy consumption is only 1/2 that of electrodialysis and 1/40 that of distillation. Therefore, since 1974, developed countries such as the United States and Japan have turned their development focus to reverse osmosis.

Reverse osmosis desalination technology is developing rapidly, engineering costs and operating costs continue to decrease, the main development trend is to reduce the operating pressure of reverse osmosis membrane, improve the recovery rate of reverse osmosis system, cheap and efficient pretreatment technology, and enhance the anti-pollution ability of the system.

Main features

Main composition

WORKSHOP

Chengdu Yuanjin Environmental Protection Engineering Co., Ltd. is located in Tianfu New District, a national new district in Sichuan Province, and Chengdu Yida Tianfu Smart Science and Technology City. The company has a group of professional technical teams engaged in water environment treatment for a long time, which can provide targeted design schemes. Its own production workshop directly manufactures equipment according to the design requirements, and the prefabricated equipment in the workshop is directly sent to the construction site for installation and commissioning. It is an environmental protection supplier that can provide professional environmental protection equipment manufacturing and housekeeping technical services in design, manufacture, installation, commissioning and operation.

The company is a high-tech enterprise, with professional contracting qualification of environmental protection engineering, second-class qualification of domestic sewage and automatic monitoring operation ability, 7 national authorized patents, 9 computer software copyrights, ISO quality management certification system and other qualifications and honors.

The water treatment equipment produced by the company covers domestic sewage, medical wastewater, landfill leachate, reclaimed water reuse, pure water preparation and other fields, which can meet the national, local and industrial discharge and use standards and different needs of customers.

The company has four series of integrated sewage treatment equipment, namely AT·Jin sewage treatment integrated reactor, DT·Jin sewage treatment integrated reactor, PT·Jin sewage treatment integrated reactor and MINI·Jin sewage treatment integrated reactor. Prefabricated pumping station, reclaimed water reuse and pure water preparation are all systems.

AT·Jin sewage treatment integrated reactor is a series of products adopting "AAO+ tubular membrane" process. After biochemical treatment, sewage enters the third generation external ceramic tubular membrane, and under certain pressure, macromolecular particles larger than 0.1 micron are trapped by the nano-pore filtration function of the membrane. The flux of tubular membrane is 3~10 times that of organic membrane, and its service life is 10 years, which is 3~5 times that of organic membrane.

DT·Jin sewage treatment integrated reactor is a series of products adopting "AAO+MBR" process. After anaerobic, anoxic and aerobic biochemical treatment, the sewage enters the built-in MBR membrane pool for membrane filtration, and the hollow fiber membrane wall is covered with micropores. Under the action of aeration, the sewage accelerates to flow outside the hollow fiber, and forms dynamic negative pressure filtration under the suction of self-priming pump, which does not block the membrane surface and can run continuously for a long time. Macromolecular particles are trapped in the micropores of the membrane, and clear water enters the membrane filaments through the micropores, and is pumped into the clear water pool by a self-priming pump.

PT·Jin sewage treatment integrated reactor, first of all, through biochemical treatment in anaerobic tank and aerobic tank, biological filler is added into aerobic tank, bacteria micelle, filamentous bacteria, etc. grow into microcolony on the filler, and finally a biofilm with a certain thickness is formed. The oxygen content inside and outside the biofilm is different, which produces nitrification and denitrification to purify sewage. The biofilm will gradually fall off after aging, and the released bacteria will form a new biofilm on the surface of the filler again, and the biochemical cycle treatment will continue. After that, chemical dephosphorization is added to the effluent, which enters the inclined tube sedimentation tank to effectively separate the mud and water.

MINI·Jin sewage treatment integrated reactor, with small equipment size, flexible layout of internal space and various shapes, is a small equipment for rural sewage treatment.

The integrated pumping station is the lifting equipment for lifting sewage, rainwater, drinking water and wastewater, which is assembled by the factory and then transported to the site for installation. With highly integrated equipment, convenient installation and prefabricated workshop, it is gradually replacing the traditional civil pump house, which is the second generation of high-efficiency and energy-saving products.

The preparation of pure water and the reuse of reclaimed water are treated by ultrafiltration and reverse osmosis processes. According to the application approaches and standard requirements, single membrane, double membrane, one-stage and multi-stage configurations are carried out, which are used in high-standard fields such as drinking water and industrial soft water.

The water treatment equipment produced by the company is equipped with PLC control system, which can realize remote control and unattended operation, thus saving worry and effort for customers.

The company's integrated water treatment equipment, installation and operation projects are widely used in the southwest and northwest regions. In the past three years, the annual output value has increased by more than 10 million yuan, which has established a good reputation in the industry. Chengdu Yuanjin Environmental Protection Engineering Co., Ltd. adheres to the business philosophy of "focusing on sewage treatment, reappearing clear water and clearing the source", constantly improves its professional ability, develops and updates its product series, improves its quality service, and strives to build a first-class brand in the industry, helping the construction of national ecological civilization and guarding our common home!
