Problems solved by technology

[0007] However, the contact oxidation method has the following disadvantages: (1) The biofilm reserves on the filler vary depending on the BOD load; (2) The biofilm can only fall off by itself, and the remaining sludge is not easy to drain away, and it is easy to cause pollution if it stays between the filter materials. Deterioration of water quality will affect the treatment effect; (3) When honeycomb filler is used, if the load is too high, the biofilm will be thicker and the filler will be easily blocked; (4) It is easy to produce a large number of metazoans (such as rotifers); (5) Combined contact packing sometimes affects aeration and agitation

Abstract

The invention relates to the technical field of ecological environmental protection, and in particular relates to an open-channel ex-situ integrated processor for sewage and a microbial intervention water quality improvement process. The open channel ex-situ integrated processor for the sewage comprises a water inlet, a primary stirring chamber, a secondary stirring chamber, a primary biological contact oxidation tank, a secondary biological contact oxidation tank, a primary sedimentation tank, a secondary sedimentation tank and a water outlet. The microbial intervention water quality improvement process comprises the following steps: step 1, allowing sewage to enter the primary stirring chamber and throwing a medicine; step 2, allowing the mixed solution to enter the secondary stirring chamber; step 3, performing microbial intervention water quality; and step 4, performing sedimentation treatment. The open-channel ex-situ integrated processor for the sewage provided by the invention can improve treatment efficiency and treatment quality of the sewage when used for an ecological restoration project of surface water and an ecological management project of a black odor river channel;and the microbial intervention water quality improvement process can avoid the shortcomings of a traditional contact oxidation process, efficiently improve water quality of the black odor river channel, remove suspended matter in the water, and reduce the content of phosphorus, ammonia nitrogen and organic matter.

Description

technical field [0001] The invention relates to the technical field of ecology and environmental protection, in particular to an open channel off-site integrated sewage processor and a microbial intervention water quality improvement process. Background technique [0002] Integrated domestic sewage treatment device generally refers to the treatment capacity of 500m 3 Below / d, it is a domestic sewage treatment device that integrates the functions of various parts of the sewage treatment process, generally including pretreatment, biological treatment, sedimentation, disinfection, etc. This device is mainly suitable for domestic sewage and organic industrial wastewater with similar properties, such as domestic sewage with small water volume and wide distribution, which is difficult to collect by municipal pipe network. It is a beneficial supplement to the municipal sewage treatment engineering system. [0003] There are many sewage treatment processes at home and abroad, whi...
