Abstract

The utility model provides a waste water treatment system for hospitals, which is capable of treating waste water from the hospitals into standard discharge water and comprises a grate, an adjusting tank, a hydrolyzing and acidifying tank, a contact oxidizing tank, a settling tank and a disinfecting tank. The hydrolyzing and acidifying tank is used for hydrolyzing refractory macromolecule organics into micromolecule organics, and the grate, the adjusting tank, the hydrolyzing and acidifying tank, the contact oxidizing tank, the settling tank and the disinfecting tank are sequentially connected. The waste water treatment system for the hospitals is capable of treating the waste water from the hospitals into discharge water which accords with the discharge standards according to the characteristics of the waste water from the hospitals, and further, has the advantages of simple structure and low treatment cost.

Description

The hospital wastewater treatment system
Technical field
The utility model relates to a kind of Sewage treatment systems, especially a kind of hospital wastewater treatment system.
Background technology
Because the scarcity of domestic water resource, and the water pollution is more and more serious, makes Sewage treatment systems be used widely.And it is also inequality for handling the different employed Sewage treatment systemss of sewage.So need design corresponding Sewage treatment systems according to the characteristics of various sewage.
For hospital wastewater, main polluted factors is COD, BOD, SS, ammonia nitrogen, simultaneously, also contains various pathogeny mikrobes and parasitic ovum etc. in the sewage.On the basis that the sewage quality of similar hospital is investigated, obtain the sewage quality of this hospital, composite wastewater water quality is:
Numbering Pollution substance The sewage raw water quality Unit
1 PH 6-9
2 SS 150-300 mg/L
3 COD Cr 300-450 mg/L
4 BOD 5 120-230 mg/L
5 Total plate count (MPN/L) >16000 Individual/L
Can know that by last table such sewage belongs to biodegradability sewage.
As not treated direct discharging, not only pollute peripheral water surrounding, and wasted a large amount of middle water resourcess, therefore need above-mentioned WWT be become to meet " integrated wastewater discharge standard " emission standard in (GB8978-1996).Yet also be not directed against the special Sewage treatment systems of hospital wastewater at present.
The utility model content
The utility model provides a kind of hospital wastewater treatment system that can hospital wastewater be processed into effluent standard water.
Realize the hospital wastewater treatment system of the utility model purpose, the hydrolysis acidification pool, contact-oxidation pool, settling tank, the sterilization pool that comprise grid, equalizing tank, are used for the larger molecular organics of difficult degradation is hydrolyzed to small organic molecule link to each other successively.
Said grid comprises thickness twice grid.
Lay aerated conduit at the bottom of the said equalizing tank.
The sludge outlet of said settling tank is connected with sludge sump, and the sludge outlet of said contact-oxidation pool also links to each other with said sludge sump, and the supernatant outlet of said sludge sump links to each other with said equalizing tank.
The water-in of said grid is connected with septic tank, and the sludge outlet of said sludge sump is connected with former septic tank.
The beneficial effect of the utility model is following:
The hospital wastewater treatment system of the utility model has the processing that is directed against to the characteristic of hospital wastewater, is met the discharge water of " integrated wastewater discharge standard " emission standard in (GB8978-1996); And simple in structure, processing cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model hospital wastewater treatment system.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1; The hospital wastewater treatment system of the utility model, the hydrolysis acidification pool 4, contact-oxidation pool 5, settling tank 6, sterilization pool 9 that comprise septic tank 1, grid 2, equalizing tank 3, are used for the larger molecular organics of difficult degradation is hydrolyzed to small organic molecule link to each other successively.
Said grid 2 comprises thickness twice grid.Aerated conduit is laid at 3 ends of said equalizing tank.The sludge outlet of said settling tank 6 is connected with sludge sump 7, and the sludge outlet of said contact-oxidation pool 5 also links to each other with said sludge sump 7, and the supernatant outlet of said sludge sump 7 links to each other with said equalizing tank 3, and the sludge outlet of said mud sump 7 is connected with former septic tank 8.
The hospital wastewater treatment system treating processes of the utility model is following:
After hospital wastewater flows out; Through thickness twice grid 2; After leaching large particulate matters such as cotton-wool, waste residue, paper scrap, get into equalizing tank 3, the main effect of equalizing tank 3 is that the water quality of sewage and the water yield are regulated homogenizing; Make follow-up technology avoid its impact load, water outlet is squeezed into hydrolysis acidification pool 4 through sump pump.Through the residence time of control hydrolysis acidulated pool, make waste water at hydrolysis and souring stage, be micromolecular organism with the hydrolysis of organic matter of macromolecular difficult degradation, improve sewage treating efficiency.Contact-oxidation pool 5 the insides are filled with semi soft packing; Most pollution substance obtains removing in contact-oxidation pool 5; Outputted aerobic water gets into settling tank 6; Settling tank 6 utilizes the efficient precipitating action of inclined tube to make mud-water separation, and supernatant adds and enters water body after disinfection by chlorine dioxide reaches standard from flowing into sterilization pool 9.Settling tank 6 bottoms have a pipe to be connected with sludge sump 7, during spoil disposal, start sludge pump, and under the hydrostaticpressure effect, mud makes settling tank mud be able to discharge through getting into sludge sump 7 pipe when liquid level descends.Mud regularly effluxes in the sludge sump 7.At the bottom of equalizing tank 3 ponds, lay aerated conduit simultaneously, in operational process, carry out the oxygen that exposes to the sun intermittence, make waste water form an anaerobism-circulation of oxygen of holding concurrently, carry out denitrogenation dephosphorizing.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineering technical personnel in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
