Polluted water ecology dialysis apparatus and processing method

Abstract

The invention discloses a polluted water ecology dialysis apparatus and a processing method; the ecology dialysis apparatus comprises a sealed reaction tank having an I zone, an II zone and an III zone connected in sequence; different biology filling materials are arranged in different zones; the polluted water enters the ecology dialysis apparatus, and flows through the I zone, the II zone and the III zone in sequence for purifying treatment. The polluted water is regarded as medium; a minisize ecology system is fast constructed on the filling material, and pollutant in the polluted water is constantly degraded, thereby realizing the purpose of using pollutant to treat pollution; processed water outflow contains massive beneficial organisms, and an original ecology system receiving the water cannot be harmed. The polluted water processing method has no chemical addition, no sludge, no stink discharge, and no secondary pollution. The polluted water processing apparatus is less in investment, small in occupation space, simple in operation management, easy for promotion and application, and is suitable for polluted water treatment in many scopes.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an ecological dialysis device and a treatment method for polluted water. Background technique [0002] Water is the source of life, sewage is the source of death. According to statistics, the water quality of more than half of the seven major river systems in China has been polluted, 17 of the 35 key lakes are seriously polluted, more than 90% of the urban waters are seriously polluted, the water sources of more than 50% of the cities and towns do not meet drinking water standards, and 40% of the water sources It is no longer drinkable, and people have paid great attention to the treatment of sewage. In 1912, Clark and Gage in the UK invented the sewage treatment technology of activated sludge method, which is still widely used today, and there is no essential improvement in technology. The sludge activation method is a chemical-based "cocktail" mixing technology, incl...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional sewage treatment mode is a large open and non-closed sewage treatment system, which cannot circulate in a region or locally. Long-distance transportation leads to the spread of pollution. It is inevitable that pipeline leakage will also affect the surrounding and groundwater. body poses great danger

The traditional sewage treatment mode has low efficiency and poor effect

[0004] 2. The traditional sewage treatment mode is prone to secondary pollution problems such as sludge and odor during the treatment process. It is equivalent to a sewage plant and is also a "pollution source" (sludge, odor), which cannot fundamentally solve the pollution problem

[0005] 3. Most of the traditional sewage treatment processes are treated by chemical methods, so that the treated effluent is "chemical water", which does not have the function of ecological regulation. The residual chemical substances in it are easy to damage the original ecological system of the receiving water body, which is not conducive to the environment The overall purification of the environment and the construction of a large ecological system

[0006] 4. The traditional sewage treatment mode adopts centralized treatment, which occupies a large area and consumes high power, which brings a huge burden on energy and does not meet the purpose of energy saving and emission reduction.
