5, Nh
3, ss, chlorine residue etc. can not qualified discharges.
Summary of the invention
Purpose of the present invention will overcome above-mentioned deficiency exactly, provide a kind of effective, can qualified discharge, do not cause secondary pollution, can disinfect at regular time and quantity, innocent treatment process for hospital sewage that processing cost is low, the present invention also will provide a kind of device for automatically controlling of this innocent treatment process for hospital sewage.
For achieving the above object, technical scheme of the present invention is that this innocent treatment process for hospital sewage comprises the steps:
(1) to the hospital sewage precipitation process that removes the gred, so that follow-up processing and classification are handled;
(2) homogenizing that is hydrolyzed of the hospital sewage through the slagging-off precipitation process is handled, to improve follow-up microbiological treatment effect;
(3) hospital sewage of handling through the hydrolysis homogenizing is carried out microbiological treatment, under the situation of hospital sewage aerator aeration oxygen replenishing in the pond,, eliminate the organism in the sewage by the effect of the aerobic bacteria on the biologic packing material in the pond;
(4) hospital sewage through microbiological treatment is carried out the mud separation and disinfect, make sewage become clear; Generally realize that by conical tank mud sinks to separating, with dioxide peroxide or chlorinated lime isolated mud is piled rotten sterilization then, dry again and burn the back discharging with mud sinking swash plate;
(5) carry out the chemical disinfection processing to separate the hospital sewage of disinfecting through mud; Available dioxide peroxide is disinfected at regular time and quantity;
(6) to eliminate the processing of this chemostefilant secondary pollution through the hospital sewage of chemical disinfection processing.The disinfection of general usefulness dioxide peroxide, available dechlorinating agent is eliminated the secondary pollution of disinfection agent of chlorine dioxide at regular time and quantity.
The microbiological treatment of described step (4) repeats secondary at least continuously.
The device for automatically controlling of described innocent treatment process for hospital sewage, comprise slagging-off delay switch circuit, liquid level control circuit and the delay switch circuit of being controlled by this liquid level control circuit, described delay switch circuit comprises be mutually related aeration delay switch circuit and dispensing delay switch circuit.
Described aeration delay switch circuit is mutually related 2 at least.
Described dispensing delay switch circuit is mutually related 2 at least.
With existing Hospital Sewage Treatment technology relatively, the present invention to hospital sewage carry out self-skimming precipitation process, the processing of hydrolysis homogenizing, microbiological treatment, mud separate disinfect, chemical disinfection is handled, eliminate the processing of this chemostefilant secondary pollution.Described microbiological treatment repeats secondary at least continuously.
Treatment step of the present invention is realized control automatically by its device for automatically controlling.Like this, make the present invention be used for the harmless processing of hospital sewage, not only effective, labour intensity is little, disinfection at regular time and quantity, saved chemical agent, processing cost is low but also do not produce secondary pollution, make the hospital sewage emission compliance, i.e. hospital sewage discharging reaches GB18466-2005 " Discharge standard of water pollutants for medical organization ".
The present invention has been used for Huaihua City second the People's Hospital sewage disposal, detects through Huaihua City environment protection and monitoring station, and the result is as follows:
As can be seen from the above table, the hospital sewage after the present invention handles, every index all is lower than the GB18466-2005 national standard, and also promptly the hospital sewage of discharging has reached national requirements.
Description of drawings
This accompanying drawing is a device for automatically controlling synoptic diagram of the present invention.
Embodiment
Innocent treatment process for hospital sewage of the present invention carries out as follows:
(1) hospital sewage is carried out the self-skimming precipitation process;
(2) homogenizing that is hydrolyzed of the hospital sewage through the slagging-off precipitation process is handled;
(3) hospital sewage of handling through the hydrolysis homogenizing is carried out microbiological treatment three times with aerobic bacteria; Under the situation of hospital sewage aerator aeration oxygen replenishing in the pond,, eliminate the organism in the sewage by the effect of the aerobic bacteria on the biologic packing material in the pond;
(4) hospital sewage through microbiological treatment being carried out automatic mud separates, generally realize that by conical tank mud sinks to separating with mud sinking swash plate, then with dioxide peroxide or chlorinated lime isolated mud is piled corruption and sterilization, dry again and burn the back discharging;
(5) quantitatively carry out the chemical disinfection processing to separate the hospital sewage self-timing of disinfecting through mud with dioxide peroxide;
(6) hospital sewage to handling through the dioxide peroxide chemical disinfection quantitatively carries out dechlorination with the dechlorinating agent self-timing and handles, to eliminate this chemostefilant secondary pollution.
