River sewage treatment equipment with sludge residue storage treatment function

Abstract

The invention relates to the technical field of river sewage treatment, and discloses river sewage treatment equipment with a sludge residue storage treatment function, which comprises a water gate, an aeration tank, a biochemical tank, a discharge tank and a recovery tank, and the water gate, the aeration tank, the biochemical tank and the discharge tank are sequentially mounted on a river from left to right; sludge at the bottom of the aeration tank is sucked to a sludge crushing and drying device through a powerful self-suction slurry pump, a discharge port of the sludge crushing and drying device is connected with a belt conveyor, and a discharge end of the belt conveyor is arranged above the recovery tank; the device can simultaneously achieve the effects of aeration and garbage cleaning, is ingenious in structural design and low in cost, and can also solve the problem that an aeration wall is easily blocked by garbage; and the mud suction gun head can be driven to move back and forth in a reciprocating mode, all-directional suction of mud at the bottom of a river channel is achieved, the input cost of the mud suction pump is reduced, and the energy-saving and environment-friendly concept is met.

Description

technical field [0001] The invention relates to the technical field of river sewage treatment, in particular to a river sewage treatment equipment with sludge residue storage and treatment. Background technique [0002] Urban river ecology is a fluid and relatively open complex ecological system in the urban landscape that is closely related to the living environment of urban residents. Rivers have a certain ability to purify and recover from source pollution. However, due to the large number of residents along the banks of urban rivers, the production and life of residents have a huge impact on urban rivers, resulting in the continuous degradation and loss of ecological functions of urban rivers, black odor, mosquito breeding, etc. , not only loses its function as an urban landscape, but also becomes a burden on the city, interfering with the normal production and life of residents and affecting the reputation of the city. [0003] River sewage treatment means that in orde...

Problems solved by technology

[0005] For example, Chinese Patent No. CN202111300717.4, which discloses a river sewage treatment device with sludge treatment, is not convenient for conventional river sewage treatment devices Automatic cleaning of the sludge filtered out of the tank will easily cause blockage of the filter screen and affect the efficiency of sewage treatment. The following scheme is proposed now, which includes a box body and a filter screen. The top of the box body is provided with an opening. The filter screen is slidably installed in the box, and both sides of the top of the filter screen are fixedly connected with connecting rods, and the top of the two connecting rods is fixedly installed with the same sealing plate, and the sealing plate is movable and sealed inside the box body. Four vertical rods are fixedly installed, and the top of the four vertical rods is fixedly installed with the same push plate

[0006] However, there are still some shortcomings in the existing equipment: when performing aeration treatment, the suspended garbage in the sewage will entangle or block the aeration device, resulting in aeration The effect is not ideal; the suction mud pump can only suck the sludge at a fixed position, resulting in insufficient sludge suction. If multiple suction mud pumps are installed for suction, the investment in equipment must be increased
