Rubbish penetrating fluid and urban sewage treatment device

Abstract

The invention discloses rubbish penetrating fluid and an urban sewage treatment device. The device comprises a disinfection and sterilization tank, a heavy metal separation tank, a secondary reactiontank and a precipitation tank, wherein the disinfection and sterilization tank, the heavy metal separation tank and the secondary reaction tank are all internally provided with stirring paddles whichare driven by a motor arranged above, the outer sides of the disinfection and sterilization tank, the heavy metal separation tank and the secondary reaction tank are respectively provided with a firstliquid storage bucket, a second liquid storage bucket and a third liquid storage bucket, in the second liquid storage bucket, a stirring paddle is arranged, a stirring motor is arranged above the second liquid storage bucket, the front end of the disinfection and sterilization tank is connected with an ammonia nitrogen air stripping tower, a water inlet is arranged above the ammonia nitrogen airstripping tower, a water outlet is arranged below the ammonia nitrogen air stripping tower, and the water outlet is connected to the disinfection and sterilization tank through a pipeline. The urban sewage treatment device can be used for achieving efficient and stable treatment of the filtration and decomposition of organic matter, nitrogen, phosphorus and heavy metal, and the discharge standardis met.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment equipment, in particular to a treatment device for garbage permeate and urban sewage. Background technique [0002] As a water-soluble component, landfill leachate has very high chemical oxygen demand and biological oxygen demand, and contains a large amount of organic matter, nitrogen, phosphorus, and heavy metals, etc., with high concentration and deep color. Landfill leachate will cause serious environmental pollution to the surrounding groundwater and surface water. A large number of groundwater pollution incidents in landfills show that leachate is the most important source of groundwater pollution. [0003] The leachate contains a lot of toxic substances with a high concentration, which has become a huge threat to the environment. The leachate is completely discharged into rivers and lakes without treatment. The organic and inorganic pollutants in it will pollute aquatic organisms...
