Embodiment Construction
[0017] The diaphragm overflow weir type water outlet device proposed by the present invention has a structure such as figure 2 As shown, it includes a C-shaped air chamber 3, an outlet overflow weir 5, and a water flow channel formed between the air chamber and the outlet overflow weir. The gas chambers communicate with the gas distribution pipeline 9 through pipelines respectively. The outlet overflow weir 5 and the air chamber 3 are integrated to form a water outlet module placed on the outer periphery of the sewage pool outlet channel 6, and a water flow channel is formed between the air chamber in the water outlet module and the outlet overflow weir, and a water flow channel is fixed in the water flow channel. A plurality of airbags 4 , the airbags 4 communicate with the air chamber 3 .
[0018] The device of the present invention arranges a fixed air bag between the outlet channel with the outlet overflow weir and the scum baffle on the outside, periodically inflates an...

The present invention relates to a diaphragm overflow weir type output water device, which belongs to the sewage disposal output water device technology field. The device comprises a C-shaped air chamber, a water output overflow weir, and a water channel arranged between the air chamber and the water output overflow weir. The air chamber is communicated with the distribution ducting by pipe line. The water output overflow weir and three air chambers form to one piece to form a water output module which is arranged at the outside circumference of a sewage reservoir water output channel. A water channel is formed between the air chamber inside of the water output module and the water output overflow weir. A plurality of air-bags are arranged inside of the water channel and are communicated with the air chamber. For the diaphragm overflow weir type output water device of the present invention, the operating staff can directly observe the running effect of the water output weir so as to adjust and maintain the water output weir in time according to the running condition and to improve the outputted water quality. Furthermore, the investment is low, the working and installation difficulty is small, the number of the needed control element is small and the operation and the maintenance are simple.
Description
technical field [0001] The invention relates to a diaphragm overflow weir type water outlet device, which belongs to the technical field of water outlet equipment for sewage treatment. Background technique [0002] At present, with the widespread application of the sequence batch activated sludge process (hereinafter referred to as SBR) sewage treatment process in China, especially the continuous promotion and application of various continuous flow balance water level sequence batch activated sludge processes improved on the basis of it , put forward the requirement of intermittent water discharge according to the operation cycle (stop water discharge during aeration reaction) for the traditional water outlet weir. In order to meet this requirement, foreign manufacturers have introduced an air outlet weir after research, and its structure is as follows figure 1 as shown, figure 1 Among them, 2 is an intake valve, 6 is an outlet channel, 7 is a water outlet pipe, 8 is an ex...
