Abstract
The invention provides a two-section sewage sludge treatment method, which is characterized in that: a treatment system comprises a high mud storage constant convergence digestion and saving pool and a three-phase separation pool which is in series, sewage and sludge are separated in the three-phase separation pool for respective sewage treatment and sludge treatment, maximum sludge storage constant convergence digestion and saving can be performed in the high mud storage constant convergence digestion and saving pool, sewage in the high mud storage constant convergence digestion and saving pool and sewage in the three-phase separation pool are drawn out and removed by an unequal cycle method, the method provides a space for the existence and the reduction of the sludge, avoids secondary pollution, meanwhile reduces the sewage treatment time, and saves volume space and materials.
Description
Technical field
The present invention relates to a kind of method of sewage sludge process.
Background technology
Septic tank is a kind of basic sludge treatment facilities, also be a kind of sewage disinfection treatment facility simultaneously, but along with the development in epoch, the mode abandoned substantially utilizing the corruption mud in septic tank to carry out applying fertilizer, and present stage, because the sludge treatment industry development of China is delayed, and septic tank need with regularly drawing clearly, draw out clearly the mud come in a lot of regionalization manure pit to carry out nowhere processing and dissolving, cause secondary pollution, and the waste of manpower and materials.According to the law of the conservation of matter, material can not gratuitously disappear, mud is bound to be present in certain space, and decay of progressively degrading in a certain way is until disappear, and holds back the theory of the method for dissolving according to mud weighing apparatus, sludge degradation degree is larger, the residence time is longer, then the increment of mud is less, therefore, the mode of the space that mud exists and disappearance is a kind of groundwater pollution control.In addition, septic tank has the function of sewage disinfection treatment concurrently, and because in septic tank, sewage mixes with mud, the precipitation of digestion gas to pollutent that mud produces also produces negative interference, the settlement of sewage residence time is long, with more than 12 hours, large quantization manure pit useful volume space need be occupied, waste building materials, three phase separation sewage disposal technology overcomes sewage in septic tank and contacts the technical problem mixed with mud, just can reduce dwell time of sewage, reduce sewage volume, save material.Based on above situation, design a kind of two-part sewage sludge treatment method, utilize mud auto-degradation digestive characteristic, the weighing apparatus carrying out mud is held back and is dissolved, sludge reduction, stabilization treatment can be realized, alleviate the environmental stress of specific resistance to filtration, the technical measures utilizing three phase separation can be realized again, shortening manure pit dwell time of sewage, improves the method for water quality.
Summary of the invention
The object of the invention is to design a kind of method having sewage disposal and sludge treatment concurrently.
Two-part sewage sludge treatment method of the present invention is two sections, front and back sanitary sewage pretreatment system being divided into series connection, above one section be provided with can fully store mud a high position storage mud weighing apparatus hold back pond of dissolving, connected two-story sedimentation tank or the three phase separation pond in pond of dissolving is held back below at high position storage mud weighing apparatus, the water-in in pond of dissolving held back by high-order storage mud weighing apparatus, water outlet, cross top or high level that water hole mouth is all positioned at container, maximize Cumulate Sum and store mud, and carry out weighing apparatus and hold back and dissolve, two-story sedimentation tank or three phase separation pond are formed primarily of the settling tank for waste water treatment on top and the mud room of bottom, settling tank for waste water treatment takes the streaming of rectangular sedimentation tank or inclined-plate clarifying basin or tube settler, the throw out produced in settling tank for waste water treatment sinks to mud room by the heavy mud mouth on muddy water division plate between settling bath and mud room or mud tube, the high level of mud room have upwards draw exhaust-duct clearly, for drawing clearly mud and discharge digestion gas, what high-order storage mud weighing apparatus held back that the mud of dissolving in pond and two-story sedimentation tank or three phase separation pond takes the not reciprocity time cycle draws mode clearly, for the mud in two-story sedimentation tank or three phase separation pond, according to the volume of mud increment and mud room, carry out regularly drawing clearly, the mud of dissolving in pond is held back for high position storage mud weighing apparatus, take to maximize accumulation and store mud, extend the mode that sludge retention time is dissolved, when observing high-order storage mud weighing apparatus, to hold back pond mud accumulation of dissolving excessive, or in two-story sedimentation tank or three phase separation pond mud room mud exist improper accumulation excessive time, then the mud accumulated in pond of dissolving is held back to high position storage mud weighing apparatus and draw process clearly.
Described connected below two-story sedimentation tank or three phase separation pond of holding back pond of dissolving at high position storage mud weighing apparatus, be introduced into mud room by two-stage process Link Port or pipe connecting to draw clearly space, exhaust-duct, and then passed through water hole mouth and enter settling tank for waste water treatment, or directly enter settling tank for waste water treatment by two-stage process Link Port or pipe connecting.
It is all-in-one-piece that the high position storage mud weighing apparatus of described series connection holds back dissolve pond and two-story sedimentation tank or three phase separation pond, or split type, is connected between split type by communicating pipe.
Pond body structure adopts material of construction or Other Engineering material to make, and the top plan view profile of overall container or monomer container is Polygons or circle.
It is all the processing vessel having a monomer at least that described high position storage mud weighing apparatus holds back dissolve pond and two-story sedimentation tank or three phase separation pond, can carry out serial or parallel connection between multiple similar monomer.
Described high position storage mud weighs multiple volume spaces that the inner volume of holding back pond of dissolving is a grid space or is separated by least one dividing wall (plate), the top of dividing wall (plate) is provided with at least one high position and crosses water hole mouth, and the dividing wall (plate) exceeding liquid level is provided with at least one ventilation overflow hole.
Described high position storage mud weighing apparatus hold back dissolve pond and (or) top in two-story sedimentation tank or three phase separation pond is provided with and guides extraneous vapor pipe into, the upper end face of container is provided with inspection port.
The mud of mud room in described two-story sedimentation tank or three phase separation pond, by drawing exhaust-duct clearly and inspection port draws discharge clearly, or is established at the sidewall of mud room or bottom and guides extraneous shore pipe into, outwards discharged by shore pipe.
Described heavy mud mouth or mud tube are positioned at the low level place of muddy water division plate.
In described treatment system, the water outlet in overall or monomer container downstream or rising pipe be not higher than water-in or the water inlet pipe of upstream.
The present invention is applicable to process the pretreated sewage of sanitary sewage and mud, usefulness of the present invention is to provide a kind of method having sludge reduction, stabilization treatment and raising sewage disposal work efficiency concurrently, contribute to the process handling problems improving mud, avoid secondary pollution, improve water quality, shorten the sewage disposal time, save construction cost and maintenance cost.
