Problems solved by technology

[0005] In an aerobic environment, the growth efficiency of microorganisms is the highest, and the cell matter generated by degrading a unit of pollutants is very high; aerobic treatment can support a complete food chain, including bacteria at the bottom of the food chain and rotifers at the top; the growth efficiency of microorganisms in anaerobic environment Low, dominated by bacteria, organic matter with large molecules is often degraded into small molecules by anaerobic microorganisms first, and then completely decomposed by aerobic microorganisms
Compared with aerobic biological treatment, anaerobic treatment has low operating costs, but the reaction time is long and the treatment is not complete

Embodiment 1

[0022] Such as figure 1 As shown, a carrier for sewage and wastewater treatment is a carrier used in a reactor, including a belt-shaped middle layer 101 with a fixing effect and an outer layer 102 arranged on the surface of the middle layer 101, the said The outer layer 102 is formed by planting many filaments 103 on the surface of the middle layer; the middle layer is a 3 mm thick strip, made of porous foam plastics, and the pores include many coarse pores with a diameter of 0.1-0.5 mm. The surface layer is arranged on both sides of the strip-shaped middle layer, with an average thickness of about 3 mm. The filaments are polymer fiber composite polypropylene fibers that have undergone depolarization treatment. There are many micropores with a pore size of 5 to 50 μm on the composite polypropylene fiber. .

Embodiment 2

[0024] A treatment method for a carrier for sewage and wastewater treatment, comprising depolarizing the filaments constituting the surface layer of the carrier, wherein the depolarization treatment is to place the composite polypropylene fiber filament material in an organic polyvalent positive ion PEI (polyethyleneimine[-CH 2 -CH 2 -NH-] n ) solution for 30 minutes, so that the organic positive ions are adsorbed to the surface of the negatively charged carrier filaments to form a large number of weak bonds, and the remaining positively charged groups of the adsorbed organic multivalent positive ions can be combined with the negatively charged on the surface of the bacteria group effect, thereby accelerating the process of bacterial attachment and immobilization.

[0025] Generally speaking, under the normal growth environment of microorganisms, the surface of the microorganisms has a negative charge. If the surface of the fiber material is positively charged by technical m...

Abstract

The present invention relates to carrier for treating sewage and waste water. Said carrier includes an intermediate layer with fixing action and an external layer placed on the surface of said intermediate layer. The described external layer is formed by planting numerous threadlets on the surface of the described intermediate layer, and the described threadlets must be undergone the process of depolarization treatment. Said invention also provides the concrete steps of said depolarization treatment process and its action principle for treating sewage and waste water.

Description

technical field [0001] The invention relates to a microbial carrier and a treatment method thereof, in particular to a carrier for sewage and waste water treatment and a treatment method thereof. Background technique [0002] There are physical, chemical and biological methods for the purification of sewage and wastewater. Biological methods are by far the most natural and economical and effective methods. According to the growth mode of microorganisms in the reactor, biological treatment methods can be divided into two categories-activated sludge method and biofilm method. In the activated sludge method, microorganisms are suspended in the sewage and wastewater in the form of individuals or flocs, and the suspended microorganisms are fully contacted with the sewage and wastewater through external stirring or homogenization, and through the life activities of microorganisms and microbial flocs The biological flocculation of the body can achieve the purpose of degrading and ...
