Abstract
The invention relates to a technical improvement method of an MUCT (Modified University of Cape Town) sewage treatment process, belonging to the technical field of biological sewage treatment in environmental engineering discipline. In order to further improve the comprehensive treatment efficiency of the MUCT process and improve the activity of sludge in an MUCT sewage treatment system, a bioaugmentation pool is respectively and additionally arranged in a sludge return section and a nitration liquid return section of the MUCT sewage treatment system, and a specially prepared biological active composite filler is filled in the pools as a culture medium and an adhesion carrier of microorganisms; and a part of returned sludge and nitration liquid in the sewage treatment system enter respective bioaugmentation pool, stay for a period and return to the original positions in the MUCT sewage treatment system according to different proportions after being full contact with the biological active composite filler. The invention has the advantages of simpleness and easiness in operation and obvious effect and can ensure that the performance of active sludge in the system can be improved, and the sewage treatment effect can be enhanced.
Description
Technical field
The invention belongs to technical field of sewage in the environmental engineering subject, be specifically related to a kind of technical improvement method at the MUCT biologic process for treating sewage.
Background technology
Current, the body eutrophication that nitrogen, phosphorus excessive emissions cause becomes the environmental problem that society widely pays close attention to day by day, requirement to the municipal sewage plant was also just emphasized organic removal by the past, changed on this basis to control nitrogen phosphorus removal in the sewage that eutrophication is a purpose.How to solve and the biological denitrification phosphorous removal technique of disposing of sewage in the contradictory relation and the drawback that exist, optimize the operation of biological denitrification phosphorous removal technique system, improve the biological carbon and phosphorous removal effect, municipal effluent biological carbon and phosphorous removal technology application level is significant for improving.MUCT technology is a kind of novel technology of deriving of activated sludge process, can farthest avoid nitrate to enter anaerobic zone and influence the phosphorus of putting of polyP bacteria, improve biological phosphate-eliminating efficient, simultaneously also can keep higher nitric efficiency, be particularly useful for handling the lower sewage of C/N, it is the good sewage disposal technology of a kind of development prospect, but because this technology is activated sludge process deutero-technology, the problem that still exists some activated sludge processes self to be difficult to avoid, as easy generation sludge bulking, sludge yield is higher, denitrogenation dephosphorizing effect instability and treating processes produce stench etc., therefore for this technology, be necessary to avoid occurring the problems referred to above by the characteristic of improving active sludge in its system.
Summary of the invention
The present invention is based on above-mentioned technical background, based on a series of experimental study, at MUCT sewage treatment process system, for further improving the comprehensive treating process usefulness of MUCT technology, the activity of mud in the improvement system, and rationally reduce technical cost, and do not do under the big change condition on original technology basis, carry out technological improvement by in system, setting up biologically-intensifying device.
To achieve these goals, the present invention takes following technological step:
Mud backflow workshop section and nitrification liquid backflow workshop section in the MUCT Sewage treatment systems set up biological reinforced pond respectively, and Chi Zhongjun is equipped with the biological activity compounded mix of special preparation, as the culture medium of microorganism with adhere to carrier; Make in this Sewage treatment systems a part of returned sluge and nitrification liquid enter biological reinforced separately pond respectively and stay for some time, after the biological activity compounded mix fully contacts, be back to original position of MUCT Sewage treatment systems by different ratios.By this process, under the acting in conjunction of biological activity compounded mix, has the microorganism of specific metabolic function, as bacillus, Thiobacillus, Rhodopseudomonas, micrococcus sp, Alkaligenes, acinetobacter, target Pseudomonas such as Aeromonas obtain enrichment, activation and propagation in inside, pond, can make that the performance of active sludge improves in the system, and sewage treatment effect is strengthened.
The bottom, biological reinforced pond that the biological activity compounded mix is housed is provided with aerating apparatus, and main effect provides necessary dissolved oxygen, plays the contact action that mixes to mud and filler simultaneously.Biological reinforced pond middle portion is the metal cage of filling filler, and metal cage is divided into 2 parts, Lower Half filling pumice filler, first half filling biological activity compounded mix.Into mud pipe is arranged at the top in biological reinforced pond, and shore pipe is arranged at middle part and bottom.
Positively effect of the present invention is:
1, system is stable, and good denitrification dephosphorization effect is not prone to sludge bulking, can realize the odorlessization of sewage, sludge handling process.
2, active sludge has good mud-water separation characteristic in the system, and sludge yield is low, can alleviate the sludge treatment burden significantly.
3, operation is simple, is suitable for the technological transformation to MUCT sewage treatment process system.
Embodiment
1. mud backflow workshop section and the nitrification liquid backflow workshop section in MUCT sewage treatment process system sets up a biological reinforced pond respectively, and Chi Zhongjun is equipped with the biological activity compounded mix of special preparation, as the culture medium of microorganism with adhere to carrier.
2. biological reinforced pool volume size should be decided according to the flow and the nitrification liquid return flow of returned sluge.Into mud pipe is arranged at this top, pond, and shore pipe is arranged at middle part and bottom, and the bottom is provided with microporous aeration device.Middle part, biological reinforced pond is the metal cage of filling biological active filling material, and metal cage is divided into 2 parts, Lower Half filling pumice filler, and the pumice filler is the in irregular shape natural pumice about diameter 2～3cm.
3. the operating parameter in biological reinforced pond is: the volume ratio of biological activity compounded mix and pumice filler is 1: 2; The mud and the nitrification liquid residence time are 24～48 hours in the reinforcement pond; Dissolved oxygen is controlled at the 0.5-1mg/L scope.
4. the biological reinforced pond that 10～20% returned sluges in the MUCT Sewage treatment systems and nitrification liquid are entered separately stopped 24～48 hours, after the biological activity compounded mix fully contacts, be back to original position of MUCT Sewage treatment systems again by different ratios.
Claims (1)
1. use characteristic of the present invention is: the MUCT Sewage treatment systems mud backflow workshop section and nitrification liquid backflow workshop section set up biological reinforced pond respectively, making in this Sewage treatment systems a part of returned sluge and nitrification liquid enter biological reinforced separately pond respectively stays for some time, after the biological activity compounded mix fully contacts in the pond, be back to original position of MUCT Sewage treatment systems by different ratios.
