Foreword

    The coating water treatment machine is the newly developed high-efficiency wastewater treatment system of Jinhua Jinmei Environmental Protection Technology Co., Ltd., which integrates multiple steps of the traditional wastewater treatment process through Jinmei through optimized integration (equipment size: width 3375px, length 5625px) The latest technology is simple and highly integrated. Therefore, the wastewater treatment efficiency is greatly improved, the dosage and energy consumption of the treatment process are greatly reduced, and the investment construction cost and the land occupation area of the wastewater treatment facility are greatly saved, and the sewage environment is effectively improved to promote the sewage reduction and promote clean production. Enhance corporate image.


Equipment specifications: 10 tons / hour, 20 tons / hour, 40 tons / hour



     First, the current common problems in painting systems

Through the on-site inspection of many manufacturers of the company for many years, it was learned that in all the painting workshops, the spray paint was absorbed by the water curtain and then flowed into the pool. The paint booth adhered to the bottom of the pool and the surrounding paint residue. The water flow of the water curtain board is relatively small and not dense enough, and often has a situation such as blockage of the pipeline and heavy smell. The blockage of the pipeline will cause the circulating water pump to burn out. It takes a whole day to clean the water curtain cabinet and affect the normal production. It is more troublesome to clean the pipeline and remove it. It takes a lot of time and manpower. In order to provide a better workshop environment, improve production efficiency, ensure normal production operations, and ensure the smooth flow of pipelines, it is imperative to adopt circulating water treatment equipment.

Second, coating circulating water solution

Based on the above problems, our company proposes to consider recycling in the entire system. With the rapid development of industry and the growing population, how to resolve the contradiction between development and the environment, and achieve sustainable economic and exchange coordination. Development has become a common concern of the world. More and more people realize that human beings can only change the old mode of energy consumption and environmental pollution in the past in production activities; and adopt clean production—that is, maximize resource efficiency, reduce waste, and prevent pollution. Only by reducing pollution at the end of the pollution, thereby reducing the overall cost, improving, and improving the economic benefits and coordinating with the environment, can we achieve sustainable development. Only this one, there is no other path.

Therefore, the city that cannot be denied: the environmental protection regulations will become increasingly strict. If our factory can prepare for the sewage discharge in advance to meet the environmental protection requirements, the production efficiency and corporate image of our factory will be improved.

Jinmei Environmental Protection Technology Co., Ltd. has many years of experience and results to arrive at the following final solutions:

A spray paint circulating water treatment machine is placed next to the spray booth to treat the circulating water, and the paint residue is continuously separated. The clean water generated after the treatment is directly diverted to the circulating water pump of each spray booth, avoiding the water pump and the pipeline. Blockage and problems with water curtain lacquering. In addition, the spray booth and the water treatment machine are linked to achieve non-operation, no need to change the water and clear the pool, and not discharge to the outside, thereby achieving environmental protection requirements to achieve zero discharge clean production of wastewater.

Third, the use of spray paint circulating water zero discharge processor comprehensive conclusion

     1. The circulating water becomes invented, the cod value is reduced, there is no odor, no water change is needed, the tax and water treatment costs are reduced, and green production of energy saving and emission reduction is realized;

      2. The paint slag is automatically discharged from the machine to avoid clogging the water pump and pipeline and prolong the service life of the equipment, thus further reducing the cost of maintenance, repair and replacement of equipment;

      3. The treated slag is non-adhesive, and the paint attached to the water curtain wall of the spray booth is reduced, so that the water curtain is more complete, and the paint mist can be fully absorbed to prevent the paint mist from escaping into the fan, damaging the fan and even causing fire;

      4. The painting system runs continuously. Year-on-year, savings: water fee + cleaning labor + production delay + equipment maintenance + sewage treatment costs.

       5. Environmentally friendly production creates a clean production environment for the workshop, which is conducive to the application of ISO14000 environmental management international standards for certification and improvement of corporate image.

      Fourth, the coating waste water zero discharge machine operating procedures

      1. The main control switch is turned on and the device is powered.

      2. After the equipment is powered on, open two sets of system switches (main switch A, main switch B) of the electric control box.

     3. Open the sludge pump of the two systems (sludge pump 1A, sludge pump 1B).

     4. Visually inspect the influent of the two sets of sludge pumps to the equipment reaction tank for about 1 minute, then turn on the reaction pump (reaction pump A, reaction pump B).

     5. After the two sets of reaction pumps are turned on, immediately turn on the dosing pump (AB agent A, AB agent B).

     Sixth, finally open the scraper (scraper A, scraper B), and adjust the scraper slag interval.

     Seven, note:

     1. It is strictly forbidden to idling all pump sewage.

     2. If the lifting effect of the equipment scraping slag paint slag is not good, the air pipe can be installed at the inlet valve of the reaction box, and the gas pressure is controlled below 6KG.

     3. Regular equipment maintenance.

                                          Note: It will be changed according to the actual situation of the customer.
