Continuous time 7min.In the present embodiment, 99% coliform and 97% can endophytic bacteria be removed；To angstrom Xi Shi large intestine (bar) bacterium
Bactericidal effect is 99.9% or so.
Embodiment 3
NaOH aqueous solution is as electrolyte, concentration of electrolyte 14mol/L.
The sinusoidal ac that frequency is 50Hz is power supply, is electrolysed using iron anode and graphite cathode, and current density is
88mA/cm2, the temperature of electrolysis is 30 DEG C -60 DEG C.Electrolysis is under air environment.Electrolysis time can be 60 minutes.
Contain oxidant in solution after electrolysis, the solution after electrolysis is sent into manure pit, alternatively, containing in manure pit
The sewage lifting of excrement to oxidation chamber, be sent into oxidation chamber by the solution after electrolysis.
In reaction process, the oxidant shared concentration in the sewage containing excrement is preferably 7mol/L, and the reaction is held
Continuous time 7min, reaction temperature are 15~30 DEG C.In the present embodiment, 99% coliform and 97% can endophytic bacteria be removed；
Angstrom bactericidal effect of Xi Shi large intestine (bar) bacterium is removed in 99.9% or so, 22% ammonia and nearly 99% hydrogen sulfide.
It is about 8 hours in the microbe carrier anaerobism residence time, in aerobic stage in existing Biochemical method technology
Residence time is greater than 24 hours.In the above embodiment of the present invention, it is only necessary to about 20 minutes, so that it may reach fully degraded pollutant
Purpose.The processing time for substantially reducing fecal sewage realizes the instant processing of fecal sewage.
Ferrate heavy-metal ion removal, in terms of have great advantages, but ferrate
Also there is very strong flocculating effect, promote solid deposition, therefore, in the processing of this high solids content sewage containing fecal sewage,
Have no use.But it was unexpectedly determined that the method for oxidation in the embodiment of the present invention can make the final sludge of the sewage containing excrement
Decrement persistently handle in Shanghai community and contains fecal sewage 2 years, sludgd deposition silting does not occur up to 50% or more, do not need into
The water of the cleaning of row sludge, treated water can be used as toilet flushing is recycled.
Using the method for the present invention, treated that pollutant removal situation is as follows:
Table 1, result containing fecal sewage treatment
| Project | Before processing | After processing | Removal rate |
| Sample state | Black troubled liquor | Colourless micro- turbid body | / |
| pH | 6.25 | 6.14 | / |
| COD (COD), mg/L | 1.72×103 | 19 | 98.9% |
| Ammonia nitrogen (in terms of N), mg/L | 92.4 | 0.39 | 99.6% |
| Total nitrogen (in terms of N), mg/L | 99.0 | 1.30 | 98.7% |
| Total phosphorus (in terms of P), mg/L | 11.5 | (< 0.01) is not detected | 99.9% |
Above-mentioned experimental result shows, by a kind of fecal sewage treatment method proposed by the present invention, treated that sewage can
Reach the level-one A standard in GB 18918-2002.
The fecal sewage treatment method of the embodiment of the present invention avoids the use of microorganism, is purely physicochemical side
Method, the requirement to environment temperature are extremely low.
Specific embodiments of the present invention are described in detail above, but it is merely an example, the present invention is simultaneously unlimited
