Description
Technical field
It is especially a kind of for handling the integrated stabilization pond of distributed sewage the present invention relates to a kind of sewage disposal device
Equipment.
Background technique
With the continuous improvement of China's Living consumption, the discharge amount of sanitary sewage is also increasingly increasing.Urban life
The processing of sewage uses centralized processing mode, i.e., is made of sewage collection system, centralized processing unit and disposal unit three parts:
Sewage collection system needs to be equipped with corresponding collection conduit, closed conduit and necessary boost in pressure pump house so that sewage is collected to sewage
Centralized processing unit in factory；And collect, expense caused by transportational process often account for cost of sewage disposal more than half.
For rural area township, enterprises and institutions, scenic spot, mine and sewage network can not arrival area dispersion type domestic wastewater, by
Restriction to geographical conditions and economic factor is difficult to adapt to centralized processing mode, leads to many point source sewage direct emissions.At present
Traditional septic tank mode that the country continues to use always can only play the role of it pretreated, it is difficult to reach increasingly strict country's mark
It is quasi-.Therefore, it designs and develops a kind of for handling the integrated stabilization pond equipment of distributed sewage, is difficult to make up sewage treatment
The part of scale processing, it appears it is very necessary and efficient, and wherein the selection of dephosphorization process also becomes key technology.
In recent years, it is the principal element for causing water eutrophication that the sewage of phosphorous equal nutrients, which is largely discharged into water body,.
With requiring to be increasingly stringenter to phosphorus discharge standard both at home and abroad, sewage dephosphorization technology has become the research hotspot of water treatment field.
Sewage dephosphorization technology generally can be divided into bioanalysis and two kinds of physico-chemical process.Bioanalysis relies primarily on micro- life in activated sludge and biomembrane
The assimilation of object absorbs the removal that residual active sludge was exhausted and realized again phosphorus by phosphorus, but the removal effect of the process is unstable
Fixed, the sewage of especially high concentration phosphorus is difficult to meet qualified discharge；Chemical precipitation method is although stable, efficient, but usually can
That causes secondary pollution or even chemical agent adds the corrosion etc. that will cause equipment.Compared with bioanalysis, electrolysis method dephosphorization technique
Have many advantages, such as that removal rate is high, selectivity is strong, while relative to chemical precipitation method, the sludge that electrolysis method generates is few.
The sanitary sewage of distributed sewage especially remote districts and rural urbanization, difference its water quality in the water period and water
Amount fluctuation is larger.Therefore, strong a kind of capacity of resisting impact load, Low investment, low energy consumption, unattended is researched and developed, and have and stablize,
The decentralized type sewage treatment process of efficient dephosphorization ability is to achieve effective control the inevitable requirement of distributed sewage, and contain state
The key point of interior water eutrophication trend.
Summary of the invention
The integrated stabilization pond that in order to solve the above technical problem, the present invention provides a kind of for handling distributed sewage is set
It is standby, it can be achieved that distributed sewage especially remote districts and rural urbanization sanitary sewage processing；The equipment and its treatment process
The fluctuation that water quality and water can not only widely be adapted to also has the characteristics that Low investment, low energy consumption, unattended, efficiently steady
Surely the purpose that synchronous dephosphorization is realized while removing pollutant makes to be discharged stably reaching standard realization reuse.
