Description
Technical field
The invention belongs to the technical fields such as sanitary sewage organic matter, the removal of nitrogen and phosphorus pollution thing, and in particular to one kind is new to detest
Oxygen-biofilter-sponge artificial wet land sewage treating process.
Background technology
Currently, life says that sewage, especially rural domestic sewage treatment face very big technological challenge.Country sewage has water
Amount, variation water quality are big, the features such as overall water is small, water quality regional disparity is big.Rural decentralized wastewater processing is carried out in the whole nation now
Technology species is a lot, mainly there is traditional activated sludge process, biological contact oxidation process, embrane method etc., and every kind of technique all exists corresponding
Technical problem, such as contaminant removal efficiency is unstable, operation maintenance difficulty is high, processing cost height.
Sponge urban construction is China preventing and treating city and rural area waterlogging, improves a weight of resident's productive life environment
Behave is wanted, the whole nation is just in Efforts To Develop.One of which technical way is the implementation of green measure, such as grass planting ditch, green flower
Garden, landscape artificial wetland etc., increase and are oozed under rainwater.Sewage disposal is combined with sponge urban construction, forms a kind of new
Anaerobism-biofilter-sponge artificial wet land sewage treating process, can be sanitary sewage disposal, especially rural decentralized wastewater
Processing provides a kind of new technical thought.
The content of the invention
It is an object of the invention to provide it is a kind of can effectively with reference to sponge urban construction technique it is simple, can effectively handle life
Dirt Organic substance in water living, SS, nitrogen, a kind of Novel anaerobic-biofilter-sponge artificial wet land sewage treating process of phosphorus.
At a kind of Novel anaerobic-biofilter-sponge artificial wet land sewage treating process proposed by the present invention, the sewage
Science and engineering skill is realized that described device is made up of anaerobic pond, biofilter and sponge artificial swamp, and pollutant is gone by sewage-treatment plant
Except microbial action is removed in sewage treatment process, mixed liquor separation of solid and liquid water outlet process is completed by sponge artificial swamp, will
Sewage is pumped into anaerobic pond, and the hydrolysis acidification of organic pollution etc. is carried out using the microorganism placed in the processing unit；It is laggard
The biofilter for entering to add hydrophilic macromolecule biologic packing material carries out organic matter removal；Final outflow water enters sponge artificial swamp,
Carry out nitrogen phosphorus etc. to remove, realize the qualified discharge of sewage disposal；Comprise the following steps that：
（1）Anaerobism section pollutant hydrolysis acidification
Sewage enters anaerobic pond, and anaerobism section tames the powder that stage addition average grain diameter is 60-80 microns in anaerobic sludge culture
Activated carbon is added by MLSS1000-1500mg/L as microbe carrier, enhancement microbiological concentration and activity, Powdered Activated Carbon,
Disposably add；Hydraulic detention time 24-48 hours in anaerobic pond；
（2）The biofilter pollutant removal stage
Using the continuous stream method of operation, step（1）Water outlet, which is entered by intake pump in the top of biofilter, biofilter, to be used
Hydrophilic macromolecule biologic packing material, it is easy to microorganism colonization, do not block, Durability it is high（More than 10 years）, control biological filter
Pool inner water power load takes 4-8m3/m2D, dissolved oxygen concentration is 2-3mg/L；
（3）The sponge artificial swamp pollutant advanced treating stage
Biofilter water outlet enters sponge artificial swamp by flow by gravity, and sponge artificial swamp kind is implanted with plant and micropopulation
Fall, the plant and microbiologic population are further removed to dirty Organic substance in water, nitrogen, phosphorus etc..
In the present invention, the hydrophilic macromolecule biologic packing material is arranged in biofilter using overlapped way, and it is in life
Accumulation filling rate in thing filter tank is 60-80%.
In the present invention, the sponge artificial swamp is one or two in grass planting ditch or green garden, is used as artificial swamp
Part, without individually setting up artificial swamp.
In the present invention, enhancing anaerobism section culturing sludge process is disposably added using Powdered Activated Carbon.
In the present invention, aeration uses blast aeration in step (2).
In the present invention, after testing, COD is 20-40mg/L to effluent quality, and ammonia nitrogen is less than 5mg/L, and total nitrogen is 10-15mg/L,
Water outlet SS inspections are not measured, and turbidity is 0.8-1.5NTU, reaches urban wastewater treatment firm pollutant emission one-level A standards
（GB18918-2002）；Total phosphorus concentration of intaking is less than 2.5mg/L, and water outlet is less than 0.5mg/L, reaches that urban wastewater treatment firm pollutes
Thing discharges one-level A standards（GB18918-2002）；Total phosphorus concentration of intaking is higher than 2.5mg/L, and water outlet is less than 1mg/L, reaches cities and towns
Wastewater Treatment discharges one-level B standard（GB18918-2002）.
Compared with traditional handicraft, the outstanding feature of this method：
（1）Anaerobism section is powdered activated charcoal strengthened using adding, and can quickly start.
（2）Bio-filter stuffing uses hydrophilic macromolecule biologic packing material, lightweight, microorganism easy to be filmed, the punching of water resistant amount
Hit ability strong.
（3）Artificial swamp part combines sponge City Green measure, does not increase processing unit additionally, can be with surrounding enviroment
Effective integration, with preferable novelty.
