High-concentration organic wasted water and refuse leachate zero discharge treatment system

Abstract

The invention discloses a high-concentration organic wasted water and refuse leachate zero discharge treatment system, and belongs to the field of sewage treatment. The main structure of the high-concentration organic wasted water and refuse leachate zero discharge treatment system comprises a pretreatment system, an anaerobic system, a nitration and denitrification system, a tube-type ultrafiltration MBR (Meane Biological Reactor) system, a nanofiltration system, a gas-liquid contact type evaporation system, and the like, wherein the pretreatment system is connected with the anaerobic system through a pipeline; an anaerobic circulation pool inside the anaerobic system and a denitrification pool inside the nitration and denitrification system are parallelly fixed and connected; the nitration and denitrification system is connected with the tube-type ultrafiltration MBR system through the pipeline; the tube-type ultrafiltration MBR system is connected with the nanofiltration system through the pipeline; the nanofiltration system is connected with the gas-liquid contact type evaporation system through the pipeline; the tube-type ultrafiltration MBR system is connected with a residual sludge treatment system through the pipeline. The high-concentration organic wasted water and refuse leachate zero discharge treatment system disclosed by the invention is simple in treatment process, greatly increases volume loading, is easy to install and debug, shortened in treatment time and low in energy consumption; the treated second pollutent achieves a three-stage standard, so that the zero discharge of the pollutant is realized.

Description

Technical field [0001] The invention involves a treatment system for wastewater and garbage, which is the field of sewage treatment in the environmental protection industry. It specifically involves a high -concentration organic wastewater and zero -emission treatment system for garbage filtration. technical background [0002] In the past 10 years, my country's industrialization and urbanization process has accelerated.The total urban waste increased at a rate of more than 10% per year. In 2010, my country's urban domestic waste reached more than 200 million tons.The garbage filtration solution is a high concentration, multiple -component, and vulnerable sewage produced during the waste treatment process. The 1 -ton osmotic solution is equivalent to the concentration of pollutants contained in 300 tons of urban sewage. [0003] The ingredients of urban waste landfills are complicated, and they are one of the most difficult to deal with high -concentration organic wastewater in t...

Problems solved by technology

However, although the existing organic membranes used are low in cost and high in filling area, they are prone to pressure resistance and poor oxidation resistance during use, and are easily polluted, and regeneration is difficult. The life of the membrane is generally short, and the water discharge Unstable water quality, etc.
