Description
Technical field
The invention belongs to water-treatment technology fields, more particularly to a kind of black-odor riverway administering method strengthened based on electricity.
Background technique
Urban rives are the important components of the water-based important component in basin and urban ecological system, are municipal waters
One of the index that environmental quality is judged.Lifeblood of the urban river as city not only has water circulation, water and soil conservation, water storage tune
The functions such as flood, water quality self-restraint, but also be adjustable temperature and humidity, improve urban microclimate, healthy Urban Water Environment is that city can
The important leverage of sustainable development.However as the quickening of economic fast development and urbanization, many urban river water quality in China
Pollution and Ecological degenerative problem are very prominent, or even seasonality and perennially black and odorous water phenomenon occur.Therefore, city is solved
The pollution in river, the ecology for restoring river and social function problem are passes urgently to be resolved during many urban sustainable developments
One of key task." water prevention and cure of pollution action plan " requirement that State Council prints and distributes, arrives the year two thousand twenty, the Changjiang river, the Yellow River, the Zhujiang River, preserved egg
Excellent (reaching or better than the III class) ratio of the big major river valley water quality in river, Huaihe River, Haihe River, Liaohe River etc. seven totally reaches 70% or more,
Ground level and the above completed region of the city black and odorous water control within 10%.To the year two thousand thirty, national seven big major river valley water quality are excellent
Good ratio totally reaches 75% or more, and completed region of the city black and odorous water is totally eliminated, city centralization drinking water source water
Matter reaches or is generally 95% or so better than III class ratio.
The usual water body normally transparent degree of black-odor riverway is poor, and TN, TP and ammonia nitrogen are exceeded serious, some are detained in rivers COD also
It severely exceeds, oxidation-reduction potential is low, and habitat is severe, and water body loses self-purification capacity.Cause the black smelly reason in river mainly again
External source enters two aspect of river pollution and endogenous pollution.The pollutants such as a large amount of nitrogen phosphorus and organic matter, nothing are usually contained in initial rainwater
Control the pollution situation that river can be aggravated into river.Meanwhile contaminated river is also required to fast purification, to be conducive to aquatic
The recovery of state.
For current these problems, novel fast purification facility is needed to be collected purification to first rain and to black
Smelly river water carries out strengthened purification.Electric energy is provided using wind light mutual complementing based on the artificial swamp that electricity is strengthened, utilizes iron as anode,
Graphite felt is cathode, can quickly be removed to the nitrogen phosphorus in water body, and can degrade to organic matter.Electric strengthened artificial is wet
Wetland variation efficiency can be improved in ground, reduces occupied area, is particluarly suitable for using in the treating city black foul river of soil anxiety.
Summary of the invention
The purpose of the present invention is to provide a kind of black-odor riverway administering methods strengthened based on electricity, pass through the anodic oxidation of iron
The removing of nitrogen phosphorus, high-efficient cleaning are carried out using electronics caused by scene as electron donor with the cathode denitrification of graphite felt
It is clean, the unit area treating capacity of artificial swamp is greatly increased, the construction cost of land area and artificial swamp has been saved.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:

The river water in rainwater collection pool and river is pumped to the primer pump and water pipeline of electric strengthened artificial wet land system respectively.
Further, when operation, which is intake water inlet tube by bottom, and the water after final purification is by pond body
The drainpipe discharge wetland pond body on top enters river.
Further, when carrying out rainwater treatment, rainwater is introduced by the primer pump being laid in rainwater collection pool and is hung down
Direct current artificial swamp is handled;For the just high problem of ammonia-nitrogen content in the rain, the vertical current constructed wetland is by top drainpipe
It intakes, the reoxygenation effect at top is made full use of first to be nitrified, and the denitrification and dephosphorization function progress nitrogen phosphorus of electricity reinforcing are de-
It removes, enters back into bottom.
It further, can be by the primer pump that is laid in river by rainwater in no rainwater or black smelly river burst
Vertical current constructed wetland is introduced to be handled;It, should for nitrate nitrogen in river under even in everyday situations and the higher problem of total nitrogen content
Vertical current constructed wetland is intake water inlet tube by bottom, via the denitrification dephosphorization function that denitrification and electricity are strengthened, after final purification
Water enters river by the drainpipe discharge wetland pond body on top;Carry out denitrification, the water after final purification by lower part drainpipe
Discharge wetland pond body enters river.
Further, also kind is implanted with plant on the gravel layer at the top of the pond body of vertical current constructed wetland;The plant
