Beijing Gaoantun regeneration dwtp is put into use, dam the river "keeper" add "defensive" ability
This morning, reporters from the city drainage group was informed that the Gaoantun recycling plant two officially running through the water, the sewage treatment capacity of 100 thousand tons.
Now, as the river downstream dam last "goalie" Gaoantun reclaimed water adds defensive ability, a two phase synchronous operation, can reveal the upstream sewage, sewage treatment did not prevent the Wenyu River into the territory of the city center.
The upstream dam river from northeast near and downstream into the Wenyu River, the entire 21.7 km, the basin area of 163 square kilometers. City Drainage Group, the relevant person in charge of the river dam is not long, but many residents along the region, resulting in a large number of sewage. In the two phase of the Gaoantun regeneration water before commissioning the dam along the river, North River, there are Jiuxianqiao and Gaoantun a three recycling plant, the total daily processing capacity of 400 thousand tons. However, according to statistics, the upper reaches of the sewage water in a total of Sishiersanwan tons, has more than three reclaimed water treatment capacity. "Simply put, is the" drink a "recycling plant." "Drink up" is a consequence of treated sewage can not continue along the river into the downstream dam, and the river is located in the territory of the Wenyu River deputy city center.
Gaoantun renewable water equivalent to dam the river finally goalkeeper, in order to make the "keeper" to increase the defensive ability, city drainage group and Beijing construction group, the construction of the Gaoantun recycling plant two. This morning, the reporter walked into the plant, water using semi underground style design, fully enclosed production facilities. Reporters noted that the operation of water plant has no smell, no noise, ground everywhere green landscape. Three tall white spherical tank is very eye-catching, each have a diameter of tens of meters, "that is used for storage of biogas." The staff of the plant using advanced processing technology, the main indicators of reclaimed water meet the national surface water class IV water standards.
In addition, the Gaoantun recycling plant still at the end of September last year built the largest water solution of sludge disposal center, is also Asia's largest hot water solution of sludge disposal center, a daily processing capacity of 1836 tons of sludge. By high pressure and high temperature hot water solution technique, can carry out resources, sludge reduction, stabilization, harmless treatment. In addition to its treatment of the sludge produced, also undertake surrounding water recycling plant sludge. Now the daily volume of 900 tons of sewage sludge, sludge treatment, can be used as a forest nutrient soil for seedling cultivation.
Two after completion, water pollution control pressure Gaoantun regeneration processing capacity of 200 thousand tons per day of water will greatly ease the dam of river basin, to ensure access to the city center within the territory of the Wenyu River, are of high quality reclaimed water. The staff said, the 100 thousand tons of newly reclaimed water, thirty thousand or forty thousand tons will enter the pipeline for reuse of reclaimed water, the remaining will fill into the river dam for landscape water.
