【Summary】 In terms of water utilization, Israel can be said to have reached the ultimate level, and sewage, as another type of water resource, is never neglected by the Israelis. At a sewage treatment plant named Aqwise, the reporter witnessed the Israelis' superb ability to integrate technology into every detail. This sewage treatment plant is one and a half hours' drive from Tel Aviv. Beyond a lush green vegetable field lies the location of this sewage treatment plant. Looking around, there is not much difference from the sewage treatment plants that the reporter visited in Beijing. All the steps related to sewage treatment, such as flocculation and sedimentation, are also available here. However, when the staff of the water plant pointed at it with their hand, the small plastic particles rolling in a pool of sewage caught the attention of the reporters. The thousands of small plastic particles churning with the water waves in the sewage pool are precisely the "core technology" of this sewage treatment plant. Beside a circular sewage sedimentation tank, the staff told the reporter that they were using the latest biological sewage treatment technology here. They have developed a small particle called "biomass carrier", which is a circular plastic structure, each about the size of a dice. Due to the numerous cavities inside, it has a large surface area. In the wastewater tank, these small particles will provide more growth space for the bacteria that decompose harmful substances in the sewage, allowing them to grow and reproduce rapidly to consume more biological waste. Beside a sewage mixing tank, workers used a net to scoop up some small particles. These originally blue and green particles had all turned black under the adhesion of bacteria. Surprisingly, these treated sewage turned out to be the main water source for irrigating the nearby vegetable fields. The reporter was led to the vegetable plot they passed by when entering the sewage treatment plant. In this lush green field, carrots, lettuces and potatoes were growing very vigorously. A farmer who takes care of this plot of land told the reporter, "All the irrigation water for this plot comes from the reclaimed water treated by the sewage treatment plant." The water source is very safe. We usually eat the crops produced in this field. The treated reclaimed water not only nourishes this land but also supplies a large area of other land. The treated water, although it does not meet the drinking standard, is sufficient for agricultural irrigation. The staff said that these reclaimed water, through designated water pipelines, are channeled into reservoirs used for agricultural irrigation in different regions. The pumping station control center, based on the agricultural water demand in various regions and the water reserves in each reservoir, promptly adjusts the water output of each reservoir. In his view, the difference between this new technology and traditional sewage treatment lies in that it takes up less space, shows quick results and does not pollute the environment. At present, Israel leads the world in wastewater recycling. 70% of urban and industrial wastewater is recycled and transported to the arid and desert areas in southern Israel to irrigate farmland, a proportion three times that of Spain, which ranks second in the world. In addition to the treatment of sewage, Israel's management of reservoirs also has a somewhat high-tech cinematic flavor. At the National Water Company of Israel, there is a huge artificial lake, which is called the "National Water Strategic Reserve Base of Israel". Under special circumstances, this war reserve reservoir can ensure the water supply for all Israeli citizens for seven days. From a distance, this reservoir looks like an artificial lake in a park, but it is surrounded by barbed wire and guarded by armed soldiers. After being reviewed and released, the reporter arrived at the "command tower" of the reservoir. Here, a row of computers and two or three engineers can, with just a few taps of their fingers, access a wealth of information about the water quality, supply situation, and safety of all the reservoirs in Israel through the Internet, and it is under 24-hour real-time monitoring. Here, not only can the microscopic conditions of even each water pipeline be observed, but also the entire water network of Israel can be comprehensively grasped. It is reported that as long as the command tower issues an order, it can even remotely control the Sea of Galilee at the northernmost tip of the country. How long the sluice gates are opened and how many cubic meters of water are released are all under the control of this small command tower. After the trip to Israel, the reporter was full of admiration for their ubiquitous water technology. Under harsh natural conditions, the Israelis, with their wisdom and relying on high-tech means, have made themselves a country that never lacks water in the desert. These techn
