Embodiment Construction

[0029] Several stainless steel grids (10) with an aperture of 100-200mm are fixed inside the reaction tower body (3), among which stainless steel grid 1# and stainless steel grid 2# are alternately arranged to realize staggered installation, and the upper and lower distances are 300- 500mm, and fill the light filter material (9) inside the reaction tower body (3), the particle size is 10-20mm, and the density is lower than water.

[0030] The top of the reaction tower body (3) is connected to the water distribution pipe (1), and the water distribution head (2) realizes uniform water distribution at the top, and the raw water entering the reaction tower body (3) forms a biofilm on the surface of the light filter material (9). Function, purify raw water quality. The bottom of the reaction tower body (3) is connected to the perforated aeration pipe through the air pipe (4), which realizes efficient use of oxygen while ensuring low energy consumption of the fan. An anoxic layer a...

Abstract

The invention discloses an effective bioreactor with a lightweight filter material. The effective bioreactor with the lightweight filter material comprises a reaction tower body, a water distributionsystem, the lightweight filter material, an anti-blocking system, an aeration system, a water outlet system and an internal circulating system, wherein raw water enters the reaction tower body throughthe water distribution system; in an inlet water reaction process, the lightweight filter material moves upwards along with water level under the effects of buoyancy and aeration; after the water level in the tower body reaches to a certain height, rapid water drainage is controlled through automatic siphon of the water outlet system; the lightweight filter material can also rapidly descend alongwith reduction of the water level in the tower body and the self-weight; and therefore, in the inlet water reaction process, the filter material can ascend and descend in cycles; by perturbation of the anti-blocking unit which is fixedly mounted in the tower body, the problems of caking of the lightweight filter material, short flow and unevenness of water vapor and reduced treatment efficiency are avoided effectively, various wastewater can be treated, and the effective bioreactor with the lightweight filter material is particularly suitable for treating high-concentration and high-ammonia-nitrogen organic wastewater which is difficult to degrade, is low in cost and low in running cost, and runs stably.

Description

technical field [0001] The patent of the invention relates to a sewage treatment device, which specifically belongs to a light-weight filter material high-efficiency bioreactor. Background technique [0002] The existing biological filter tower or biological trickling filter has low processing load, high cost, and is prone to clogging, especially in the treatment of high-concentration organic wastewater, with a large amount of residual sludge, and the filter material is easily blocked, resulting in uneven water and air distribution. , so the processing efficiency is low and the operation is difficult. Contents of the invention [0003] In response to the above problems, our company has invented a light-weight filter material high-efficiency bioreactor, including a reaction tower body, a water distribution system, a light-weight filter material, an anti-clogging system, an aeration system, a water outlet system, and an internal circulation system. Among them, there is no f...
