Abstract
The invention discloses a biofilter with a rotary water distributor. The biofilter comprises a filter tank, a filter bed, a water distribution device and a drainage system. The filter bed is arranged in the filter tank and comprises broken stones or a plastic filter material. The water distribution device is a rotary water distributor. The bottom of the filter tank is provided with a water feeding pipe. The bottom of the filter tank is provided with the drainage system. Tank walls are arranged around the filter bed. The tank walls are prepared from bricks, stones or concrete blocks by building. The biofilter has a simple structure, has uniform water distribution effects and has high treatment efficiency. The tank bottom has slightly poor drainage effects and the fake drainage bottom is prepared by building blocks or grid plates by laying, the filter material is accumulated on the fake drainage bottom, the tank bottom supports the filter material and discharges fed water on the filter bed, a water collection ditch is arranged on the axle of the tank bottom, bottom surfaces at two sides tilt to the water collection ditch and the gradient of the tank bottom and the water collection ditch is in a range of 1-2%.
Description
Technical field
The present invention relates to field of sewage treatment, particularly a kind of biological filter with rotary type water distributor.
Background technology
Biological filter is a kind of fixed-film biological reactor of non-submersion, and cloth spills waste water continuously at an upper portion thereof, is processed when waste water flows through microbial film.Existing biological filter is due to the defect of self structure, and water distribution is uneven, cause processing efficiency slightly poor, and drainage effect at the bottom of pond is slightly poor.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of biological filter with rotary type water distributor, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
A kind of biological filter with rotary type water distributor, comprise filter tank, filter bed, water-distributing device and water exhaust system, described filter bed is arranged at the inside in filter tank, described filter bed is rubble or plastic filtering material, described water-distributing device is rotary type water distributor, is provided with water inlet pipe bottom filter tank, is also provided with water exhaust system bottom described filter tank, described filter bed surrounding is provided with pool wall, and described pool wall is by brick, stone or concrete masonry.
Described plastic filtering material is ring-shaped plastics filtrate or corrugated plastic filtrate.
Described ring-shaped plastics filtrate specific surface area is 98 ~ 340m
2/ m
3, porosity is 93% ~ 95%.
Described corrugated plastic filtrate specific surface area is 81 ~ 195m
2/ m
3, porosity is 93% ~ 95%.
The central authorities of described rotary type water distributor are a hollow column, and bottom is connected with water inlet pipe, and top is two transverse tubes be arranged symmetrically with, and described transverse tube side offers water spray aperture, and orifice diameter is 10 ~ 15mm, and not etc., nearlyer pond is not in the heart apart from larger for spacing.
Described water exhaust system by the bottom of pond, the draining false end and collecting gutter form.
Structure of the present invention is simple, filter bed can provide a large amount of surface-area for microorganic adhesion, waste water is made to flow through microbial film with liquid film state, there are enough porositys, ensure ventilate and make the microbial film come off can flow out filter tank with water, be not decomposed by the microorganisms, also do not suppress microorganism growth, have good chemical stability.Water distribution is even, processing efficiency is high, and the slightly poor draining of drainage effect at the bottom of the pond false end, is paved into building block or screen, filtrate is deposited at false the end, at the bottom of pond except support filtrate, also will drain the water on filter bed, at the bottom of pond, central axis is provided with collecting gutter, bottom surface, both sides tilts to collecting gutter, at the bottom of pond and the gradient of collecting gutter be 1% ~ 2%.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is filter tank, 2 is filter bed, and 3 is water-distributing device, and 4 is water exhaust system, and 5 is pool wall, and 6 is column, and 7 is water inlet pipe.
