Domestic wastewater treatment and storage device

Abstract

The invention discloses a domestic wastewater treatment and storage device which structurally comprises a storage tank and a connecting pipeline, the connecting pipeline is arranged on the outer wallof the storage box, the connecting pipeline is communicated with the storage box, and the connecting pipeline is arranged in a u-shaped structure; the device has the beneficial effects that when wastewater flows out through an output channel, a driving plate is pushed to move in the same direction, an elastic filter plate is dragged by a fixing rod to move along with the driving plate, and a spring which is originally in a static state is stretched, so that the spring has a reverse-retraction force as a power source for resetting the driving plate, when wastewater outputting is stopped, the driving plate loses thrust, under the action of the traction force of shrinkage of the spring, the elastic filter plate rebounds, fixed pins penetrate through filter holes on the elastic filter plate, the fixed pins eject impurities clamped in the filter holes, and the filter holes are prevented from being blocked, so that the normal use of the elastic filter plate is guaranteed.

Description

technical field [0001] The invention relates to the field of domestic wastewater treatment, in particular to a domestic wastewater treatment and storage device. Background technique [0002] my country's water resources do not match the population ratio, and with the rapid economic development, people's water consumption in various aspects is increasing day by day, so the amount of domestic wastewater excreted increases accordingly. In fact, only a small part of the wastewater has been treated, and most of it They are all directly discharged into rivers without treatment, causing waste of water resources and polluting the environment at the same time. The current domestic wastewater treatment and storage devices have the following defects: [0003] People's domestic wastewater contains impurities. The treatment of domestic wastewater requires solid-liquid separation of wastewater to facilitate the next step of wastewater treatment. The traditional solid-liquid separation meth...

[0002] my country's water resources do not match the population ratio, and with the rapid economic development, people's water consumption in various aspects is increasing day by day, so the amount of domestic wastewater excreted increases accordingly. In fact, only a small part of the wastewater has been treated, and most of it They are all directly discharged into rivers without treatment, causing waste of water resources and polluting the environment at the same time. The current domestic wastewater treatment and storage devices have the following defects:

[0003] People's domestic wastewater contains impurities. The treatment of domestic wastewater requires solid-liquid separation of wastewater to facilitate the next step of wastewater treatment. The traditional solid-liquid separation method uses filtration to remove impurities in wastewater, but when the size of impurities in wastewater When the mesh size is equal to that of the filter screen, impurities will be stuck on the filter screen, which will block the filter screen and reduce the flow rate, causing the pressure on the side of the unfiltered wastewater to be greater than the pressure of the wastewater on the filtered side, resulting in the filter screen under strong pressure. Damage or even fall off under water pressure
