THE WASTE WATER TREATMENT SYSTEM FORCAR WASHING WITH REMOVAL SAND PRECIPITATED

摘要

PURPOSE: A system for treating wastewater from car wash and simultaneously eliminating precipitated sand from the wastewater is provided to overcome shutdown problem of a car washer due to the cleaning of precipitated materials by continuously eliminating the precipitated materials. CONSTITUTION: A system for treating wastewater from car wash and simultaneously eliminating precipitated sand from the wastewater includes a reactor(101), a precipitating bath(102), and a water treating bath(103). A first filtering container(301) is attached on the upper side of the reactor. A first air lift(401) and a bubble generator(206) are installed on the lower side of the reactor. A second filtering container(302) is attached to the upper side of the precipitating bath, and a second air lift(405) is installed at the lower side of the precipitating bath. The reactor, the precipitating bath, and the water treating bath are successively integratedly connected. The system is integrated with a carwash wastewater treating unit(200).
