Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of domestic sewage processing system and side based on Internet of Things
Method.
Background technique
Be effectively treated and the stably reaching standard of town sewage are the important measures that basin water environment is administered, since Eleventh Five-Year Plan I
The urban wastewater treatment firm in state major river valley area, generally performs " urban wastewater treatment firm pollutant emission standard "
(GB18918-2002) level-one A standard in.Nevertheless, with Urbanization in China and the accelerated development of industry, river and lake is raw
State self-purification capacity weakens, environmental capacity of water is constantly reduced, and also to urban wastewater treatment, more stringent requirements are proposed for this.2015,
State Ministry of Environmental Protection has issued " urban wastewater treatment firm pollutant emission standard " (exposure draft), proposes in exposure draft
Tightened up " special limit value " standard, the IV class water standard that main indicator reaches or approaches " water environment quality standard " are wanted
It asks.
Wastewater treatment in China industry has entered world's advanced technology ranks based on activated sludge process at present.A/O activity
Sewage sludge reactor is the outstanding person of aerobe reactor, is widely used in sanitary sewage and various treatment of Organic Wastewater.
Compared to other activated sludge reactors, it has, and volumetric loading is high, hydraulic detention time is short, low energy consumption, cost is few, equipment is simple
The features such as single, easy to operate, stable, high treating effect.Have tens of thousands of A/O activated sludge process reactors in the world at present
It applies in production.But there are some birth defects for most of A/O reactors, for example interior reflux needs water pump to be promoted, and increases
Big energy consumption and failure risk, and Effluent criteria generally executes level-one A standard, is extremely difficult to " water environment quality standard "
The requirement of IV class water standard.
Currently, generally cooperating advanced treatment process, routine using activated sludge process for indexs such as COD, BOD, ammonia nitrogens
Advanced treatment process include ozone oxidation, BAF, flocculation sedimentation, filtering etc..Water outlet can be realized for traditional activated sludge process
Total nitrogen is less than 15mg/L, and stable for water outlet total nitrogen less than 10mg/L or lower, generally there are biggish difficulty.And current river
There are lands used during road restoration of the ecosystem it is nervous, sewage treatment time requirement is shorter the problems such as also cannot effectively be solved always
Certainly.
Although most domestic city has had the sewage disposal system of substantial amounts, most sewage disposal systems
The degree of automation it is not high, and be confined to artificial single-point monitoring, do not form system for unified management of overall importance.Artificial single-point prison
Control not only takes time and effort, and cannot hold the process of sewage treatment in real time, can not be according to the change of ingredient in the sewage of entrance
And adjust in real time, when this allows for the sewage entered change, sewage disposal system can not make corresponding adjustment, directly result in out
The quality of water is affected and the quality being discharged is unstable.
