Interior aeration while aeration, is added oxidant, flocculation aid and flocculant, is then allowed to stand 5-6 hours, finally by secondary sewage
The bottom precipitation substance of clarifier-tank is put into sludge collecting pit；D, the upper layer sewage feeding of secondary sewage clarifier-tank is gone into salt pond, into
Row desalting processing；E, the sewage after standing in salt pond will be gone to carry out permeation filtration, filtered solid matter be sent into dirty
Mud collecting pit, upper layer sewage are sent into three-level sewage purifier, stand 1-2 days；F, by the water after being stood in three-level sewage purifier
Body is sent into originally water station and carries out water process, and is sent into each water supply point；
G, hydrotalcite particles are put into sludge collecting pit and are stirred evenly；
H, the calcium hydroxide of 30-50mg/L is added in sludge collecting pit and is heated using heater, heating temperature 200-
250°C；
I, flyash, clay and sodium carbonate are added into sludge collecting pit and is stirred evenly, and are placed 1-2 days；
J, diatomite is added into sludge collecting pit, is placed 1 day after mixing evenly；
K, hypochlorous acid calcium powder and zinc oxide are added into sludge collecting pit, after mixing evenly, are placed 1 day；
L, the solid matter in step k treated sludge collecting pit will be carried out and carries out landfill disposal.
As a kind of improvement of this programme, in step c, air pump exposed into secondary sewage clarifier-tank into gas be ozone.
As a kind of improvement of this programme, in step h, bulk of solid matter ratio is 1:1 in calcium hydroxide and sludge collecting pit.
As a kind of improvement of this programme, in step i, flyash, clay and sodium carbonate mass ratio are 10:10:1, sludge
The ratio between solid matter mass and added flyash, clay and sodium carbonate gross mass are 3:1 in collecting pit.
As a kind of improvement of this programme, in step j, the ratio between solid matter mass is 3 in diatomite and sludge collecting pit:
1。
As a kind of improvement of this programme, in step k, sodium hypochlorite and zinc oxide mass ratio are 50:1, sludge collecting pit
Middle solid matter mass and the ratio between added sodium hypochlorite and zinc oxide gross mass are 15:1.
The utility model has the advantages that a kind of urban sewage purification technique of the present invention, the addition for various additives of making rational planning for are suitable
Sequence has the function that purifying domestic sewage, without using equipment such as destilling tower, air floatation machines, clarifier-tank is used only, subtracts significantly
Few equipment cost.Simultaneously during carrying out sewage treatment, constantly filters the solid sediment screened out in sewage and collected
Neutralisation treatment.
In step b, level-one sewage purifier carries out preliminary purification processing to sewage by way of physical absorption.Step c
In, by adding oxidant, kill microorganism in water, and impurities in water waddingization made by flocculant, facilitate it is clear, in step d
Desalting processing is carried out to sewage, originally water station progress conventional treatment can supply water sewage feeding that treated.
Unified collect to sludge collecting pit of the solid sediment collected in sewage is handled.Calcium hydroxide is as flocks
Agent destroys the rock-steady structure of solid sediment matter colloid, expands particulate interspaces.In step i, addition flyash, clay and carbonic acid
Sodium helps to solidify the heavy metal in solid sediment.Diatomite can effectively remove grease and protein etc. in solid sediment
Organic substance.Sodium hypochlorite and zinc oxide can effectively remove the stink of object sediment and suppression as deodorant and disinfectant
Microbial reproduction processed.Treated solid sediment carries out landfill disposal and does not pollute the environment with soil Tonghua.
A kind of urban sewage purification technique, process is reasonable, and equipment investment is few, at low cost, good purification, to dirt
Liquid and solid matter carry out effective purified treatment in water.
