Description

A New Type of Reclaimed Water Reuse Treatment System

technical field

The utility model belongs to the field of sewage treatment, in particular to a novel reclaimed water reuse treatment system.

Background technique

Reclaimed water is also called reclaimed water, and in factories it is also called recycled water. With the continuous growth of the population, the world's water shortage continues to spread, which is most prominent in developing countries. Even if the population growth in developed countries shows a negative value, the process of urbanization will bring about water shortages. Under this situation, new water resources must be developed, and sewage recycling is increasingly recognized as an important water resource because of its many advantages. At present, more comprehensive water resources are adopted in many areas. Resource planning and management style. Reclaimed water is between sewage and tap water. It is non-drinking water that can be used within a certain range after urban sewage and wastewater have been purified and treated to meet national standards. It can be used in many aspects of urban landscape and people's lives. In order to solve the problem of water shortage, the recycling and utilization of urban sewage has become increasingly important. Compared with the development of other water sources, urban sewage recycling has advantages. The amount of urban sewage is huge, stable, not limited by climatic conditions and other natural conditions, and can be recycled. Sewage, as a reclaimed water source, can occur simultaneously with the generation of sewage, that is to say, as long as urban sewage is produced, there will be a reliable reclaimed water source. Therefore, it is urgent to research and develop a reclaimed water recycling system that can recycle urban sewage. The treatment system is used to alleviate the current situation of water shortage, and then promote the coordinated development of environment and economy.

Utility model content

In view of the above-mentioned deficiencies in the prior art, the purpose of this utility model is to provide a new type of reclaimed water reuse treatment system, which is efficient, durable and stable, and an ozone generator is added, which can greatly improve the treatment capacity and make the effluent quality more stable.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a novel reclaimed water treatment system, including a sewage collection tank, a reaction pool, an activated carbon filter, a filter water tank, a self-cleaning filter, an ultrafiltration device, an ultrafiltration Water tank, reverse osmosis device, reuse water tank and water point, characterized in that sewage collection tank, reaction tank, activated carbon filter, filter water tank, self-cleaning filter, ultrafiltration device, ultrafiltration water tank, reverse osmosis device and reuse water The tanks are connected in sequence through pipelines, a lifting pump is arranged on the pipeline between the sewage collection tank and the reaction tank, the reaction tank is connected with an ozone generator, and the water outlet of the recycling water tank is connected with the water point through the recycling water pump. The sewage in the sewage collection tank enters the reaction tank through the lifting pump, and the ozone generated by the ozone generator reacts with the sewage in the reaction tank to remove most of the bacteria and organic matter in the water. After that, it enters the ultrafiltration device and reverse osmosis device to remove the suspended solids, chromaticity and salinity in the water. The final effluent quality meets the requirements of reused water, and is transported to the water point by the reused water pump.

Further, the ultrafiltration water tank is connected to the backwash water inlet of the ultrafiltration device through a backwash pump, and the backwash water outlet and the concentrated water outlet of the ultrafiltration device are connected to the sewage collection tank through a return pipe.

Further, the concentrated water outlet of the reverse osmosis device is connected to a reverse osmosis concentrated water tank through a pipeline, and the water outlet of the reverse osmosis concentrated water tank is connected to a discharge port through a pipeline.

Further, the reverse osmosis concentrated water tank is connected to the backwash water inlet of the activated carbon filter through a backwash pump, and the backwash water outlet and the concentrated water outlet of the activated carbon filter are connected to the discharge port through pipes.

Compared with the prior art, the utility model has the following beneficial effects: because ozone has a strong oxidizing ability (second only to fluorine), ozone has a strong sterilization effect, and is easily dissolved in sewage. Rapid reduction to oxygen, no secondary pollution to sewage, and no threat to the surrounding environment. The addition of an ozone generator greatly improves the treatment effect of the later equipment, and reduces energy consumption and the life and stability of the treatment equipment. The activated carbon filter and the ultrafiltration device in the utility model are all provided with a backwash pump, which can effectively improve the service life of the equipment, which is durable and stable.
