Green production and environmental protection are social responsibilities we must assume.  In order to reduce dust, keep the production site clean and tidy, recently, Tongya Construction Co., Ltd. built sewage tank, specialized in collecting plant sewage, reduce the scattered sand, stone, ash pollution.  

The high temperature and rainy summer brings challenges to dust control and sewage drainage.  Tongya company sprinkles water and dust around the clock, and cleans every stirring truck in time to effectively control dust, but the sewage treatment problem in the site is gradually prominent.  In order to centrally treat the sewage on site, Tongasia built three ponds, each more than 3 meters wide, 10 meters long and 3 meters deep, surrounded by a concrete wall fence to prevent the risk of falling into the pool.  The construction of three sewage collection ponds has solved the sewage discharge problems of production sites and cleaning vehicles.  Now, the factory area of Tongya company is cleaner, and the clean mixing truck reduces the scattering of sand and stones, further realizing green production.  

It is understood that Tongya company through sand and stone separation device, sedimentation tank, sewage treatment tank three links of sewage treatment, effective control of sewage discharge, sewage purification, to ensure the safety of water discharge.
