"Low carbon wind" blowing from East Island ■ Shou Shuifeng, Tao Yu, Chen Chuxiang A coastal defense company of a coastal defense brigade of the army in the southern theater is stationed on dongmaozhou Island (also known as Dongdao). This island, which was originally "covered with coral reefs and birds don't settle", is less than 1 square kilometer. Because of the heat, strong wind and many mosquitoes, it is called "Fire Island", "wind island" and "mosquito island". The officers and soldiers guarding the island have opened mountains and quarries, moved soil and opened up wasteland, planted trees and raised flowers, and given the fourth nickname here - "beautiful island". In recent years, the superior has sent four "gift bags" to "Meili island": photovoltaic power generation, wet waste processor, anhydrous washing machine and green energy supply cabin. As a couplet on the island said: "the spring breeze of science and technology blows to the beautiful island, and the life of officers and soldiers blows a low-carbon wind". Today, I set foot on the land of dongmaozhou and walk through the dense Phoenix forest. The flowers and birds sing, as if I were in a paradise. Photovoltaic power generation is the energy advantage of the island. In the past, diesel engines were used to generate electricity on the island. Generator failure, high wind and waves, untimely oil supply and power failure occurred from time to time. Later, the construction of solar photovoltaic power station was started on the island, and the days of power restriction and power failure are gone forever on the island. Through the garage, dormitory building and the roof of the club, there are solar panels. Control box and storage battery are placed in the control room. "With this set of equipment, it is more convenient for us to use electricity on the island! The island has sufficient sunshine and high installed capacity of the power station, which can meet the power consumption for the training of officers and soldiers on the island." Yang Yongfu, the electrician leader of the company, said that he has been responsible for power generation on the island for more than 10 years and has witnessed the changes in power consumption on the island - from hand-held generators to new diesel engines, and then to solar photovoltaic power plants. The renewal of three generations of power generation equipment reflects the gratifying changes on the island. Photovoltaic power generation has many benefits. Photovoltaic modules can not only generate electricity, but also play a role in shading and heat insulation after a large area of roof is laid. "We 'turn waste into treasure' into fertilizer for breeding. Now there is less waste on the island and the environment is better." Staff sergeant Wang Yeli, who is in charge of the company's logistics, wiped his new equipment "wet waste processor" and said with a smile. The ecological environment of the island is fragile, and domestic waste will affect the marine environment around the island. Previously, the company allocated garbage bins for garbage classification. The "wet waste processor" further promotes the classified treatment of waste. One of Wang Yeli's daily tasks is to put the classified wet waste into the "wet waste processor", which is crushed, stirred, fermented and degraded by machines. The output can be used to raise livestock, or fermented with garden green leaves and weeds to become fertilizer. "The officers and soldiers guarding the island take the island as their home, constantly build the natural ecological environment of the island and improve the environmental protection mechanism of the island and reef. At present, there are 260 kinds of tropical plants on the island, more than 100000 plants, and the vegetation coverage rate is up to 90%. The island has become a 'Green Island'." Company commander Lu Haowen said. The training task of the company is heavy, and it is normal for officers and soldiers to be "covered with soil in sunny days and mud in rainy days". Because it is far from land, the island lacks fresh water, the salt content of well water on the island is high, which affects the washing effect, and it is not easy to dry clothes. The newly equipped "water free washing machine" solves these problems. This new washing machine has no water and less consumables. It can wash more than 20 pieces of training clothes at a time, which can basically meet the needs of daily life. It is also different from traditional dry cleaning, mainly through "cracking bacterial stains, microwave efficient decomposition, ultrasound" and other treatment technologies, it realizes the "petty water" and the recycling of ecological laundry solvents, reducing the cost of pollution control. In the two huts, soilless vegetables grow green under the light. This is the "green energy supply cabin" in Dongmao island. In the past, the officers and soldiers guarding the island ate fresh vegetables by sea. In case of typhoon and other weather, the supply ship could not get on the island. Not long ago, the higher authorities built a "vegetable factory" on the island to achieve self-sufficiency in green leafy vegetables on the island. Sergeant Yang Guo introduced that the "green energy supply cabin" is a new three-dimensional planting equipment with off-line energy supply, full intelligent control and efficient production. "Compared with the sunshine greenhouse, the output per unit area is high, healthy and environmental protection". "Nowadays, soldiers like to enjoy vegetables in the 'green energy supply cabin' in their spare time." Yang Guo said. Standing in the "green energy supply cabin", company instructor Wang yepeng counted the ecological changes in dongmaozhou: with the establishment of an ecological water system, officers and soldiers can drink high-quality drinking water in the platoon room; The fully automatic sewage treatment system does not stop running, and can treat more than 10 tons of various wastewater every day (outlook new era)
