    Project overview

 

In July 2017, China Water Environment Group, the general construction unit of the emergency treatment project of shrimp Zihe sewage outlet in Honggrang District, signed a construction contract and an operation service contract with Lvheng Science and Technology for not less than one year. Lvheng Science and Technology is fully responsible for the supply, installation and commissioned operation of 25,000 m < sup > 3 / D emergency sewage treatment station.


The project uses five GreenEver high-efficiency non-power sewage purifiers with self-circulating high-density suspended sludge filtration technology as the core, complete dosing and sludge dewatering equipment, and the total operating power of the system is about 110 kW. The construction address is terraced with 480m < sup > 2  usable area and 400m < sup > 2  usable area.


The company leaders attach great importance to the construction quality and progress of the first project in Guizhou Province, and specially appoint experienced project managers and engineers to participate in the construction of the project. Civil engineering started on July 17. From July 27 to August, all the main equipment and materials arrived at the site in batches and cross-construction and installation. In order to ensure the timely completion of the construction plan, the site Project Department overcomes the practical difficulties such as rainy days, complex surrounding hoisting and installation environment, and many obstacles. It formulates reasonable plans, organizes 24-hour continuous construction in shifts, completes all the installation work on August 16, and successfully completes the system linkage debugging and operation at one time.
