Wastewater and reclaimed water recycling treatment system

Abstract

The invention discloses a wastewater and reclaimed water recycling treatment system. Sewage is firstly fed into an anoxic pond for anoxic hydrolysis, as the sewage has a high organic matter concentration, microorganisms are at an anoxic state at the moment, the microorganisms are facultative microorganisms, organic nitrogen in the sewage can be converted and decomposed into NH3-N by the microorganisms, and in addition, an organic carbon source is adopted as an electron donor to convert NH3-N and NO3-N into N2; secondly, the sewage is further fed into an aerobiotic pond from the anoxic pond, under appropriate conditions of dissolved oxygen and nutrition in the sewage, the microorganisms of the sewage are massively reproduced and inhabit on packing in the pond to form a biological membrane,organic matters can be adsorbed and degraded by the biological membrane when flowing through the packing along with the sewage, and thus the sewage can be purified; and finally, the sewage is fed intoa settling pond from the aerobiotic pond, peeled biological membranes and activated sludge can be removed, the precipitate effluent is fed into a sterilization pond, and a water source can be provided for later filtering. By adopting the set of the treatment system, living sewage can be well treated, and the living sewage can be further purified.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a waste water and reclaimed water reuse treatment system. Background technique [0002] Water shortage and water pollution are important issues we need to face at present, so water recycling has become an important research topic. [0003] Among them, a large amount of domestic sewage will be produced in human life. Compared with industrial sewage, the pollution degree of these sewage is small, and it is especially suitable for recycling. In order to recycle domestic sewage, the activated sludge method is often used to treat domestic sewage in the prior art, and the treated sewage is directly used for greening, flushing toilets, and road surface cleaning. [0004] However, the purification degree of the domestic sewage treated by the activated sludge method water treatment device is still too low, and there will still be a certain amount of pollutants in the treated water, which ...

Problems solved by technology

[0004] However, the purification degree of the domestic sewage treated by the activated sludge method water treatment device is still too low, and there will still be a certain amount of pollutants in the treated water, which does not meet the standards for domestic sewage recycling. This technical problem needs to be further solved
