The reactor has a compact structure and can be used for factories and enterprises with small sewage quantity, and subsequent reconstruction and expansion and equipment production are facilitated due to a modular structure.
Description
Technical field
The present invention relates to the collaborative biological filter of a kind of deposition combination type reactor, can be used for the domestic sewage treating device.
Background technology
The land resources day in city is becoming tight, and the land used of municipal sewage plant is received control.Therefore it is little to build floor space, and the novel sewage disposal technology that processing efficiency is high is fit to China's national situation, is the emphasis of WWT research, and the answer that promotes water surrounding is had important practical significance.
BAF is a kind of form that is developed out by ordinary biofilter, and it integrates holding back of suspended substance and bio-oxidation, and it is little to have floor space; Effluent quality is good; Advantages such as no sludge bulking, but the SS of water inlet is required relatively strictness, therefore need carry out pre-treatment to water.
The phosphor in sewage nutrition content increases, and be disposed to natural water after the WWT and still contain a large amount of phosphorus, be the major cause that causes eutrophication.Can know from present research, adopt the BAF phosphor-removing effect relatively poor merely, must adopt chemical enhanced effectively dephosphorization, the purpose of this patent is to solve the problem that above-mentioned BAF exists, and a kind of WWT combined reactor is provided.
Summary of the invention
For addressing the above problem, the present invention includes coagulation device, settling tank and BAF.Reactor drum comprises water collecting basin (1); Water collecting basin is connected with settling tank (5) through sump pump (2); On the pipeline section that connects sump pump (2) and settling tank (5), tubular static mixer (4) is installed; Settling tank (5) bottom is connected to shore pipe (19), and the settling tank water outlet gets into BAF (6) through overflow.Aeration tube (11), back flushing water inlet pipe (15), rising pipe (9) are installed in described BAF (6) bottom; Aeration tube (11) is connected with air (10); Back flushing water inlet pipe (15) is connected with backwash pump (14); Settling tank (5) places BAF (6) inside, and BAF (6) inner stuffing is a composite zeolite filter material.
Described coagulation device is a tubular static mixer, simple in structure, advantages of small volume, do not need special occupied ground, install easily, less investment, long service life, mixing efficiency be high.Reach the purpose that the energy is saved in the moment mixing.
The water inlet of deposition part is that through the deposition part, SS content significantly reduces in the former water by the mixing liquid of water pump pressurization through coagulation device, for follow-up BAF provides best influent quality parameter, and gets rid of most of phosphorus in the water.
There are filtrating area and exhalant region in described biological filter; The built-in self-made fill of filtrating area; The bottom links to each other with exhalant region through the porous supporting plate, and the water after the precipitation process is via settling tank top overflow entering filter tank, for aeration even; Be provided with aeration head in the exhalant region, be connected with air through aeration tube.
The distribution district of the exhalant region of bottom during as aeration, the water distributing area during also as back flushing, backwash tube links to each other with backwash water through force (forcing) pump.
Settling tank is vertical-flow, and outer wall is a cylinder shape, and BAF is built in its outside for cylinder shape, and the outer wall of settling tank is as the inwall in filter tank, UNICOM not mutually, and settling tank water is by top overflow to filter tank, and the operation in two ponds is not disturbed mutually, and is stable.
The utility model compact construction, modular construction are convenient to the later stage reorganization and expansion, and equipment production, can be used for the less factory and enterprise of sewage quantity.Through physics, chemistry and biological treatment to sewage, reach the purpose of sewage purification, help to protect environment, economize on resources.
