Municipal sewage filtering device and method

Abstract

The invention relates to a municipal sewage filtering device and method. The municipal sewage filtering device comprises a box body, a sewage lifting device, a filtering chamber, a liquid level controller and an intelligent controller, wherein the sewage lifting device and the filtering chamber are arranged in the box body and are respectively connected with the intelligent controller arranged outside the box body by a circuit; the discharge pipe of the sewage lifting device is provided with a check valve and a gate valve; the filtering chamber is connected with a sewage inlet pipe; one end of the liquid level controller is arranged in the box body, and the other end of the liquid level controller is connected with the intelligent controller by a circuit; in the sewage filtering device, a sediment cutting and crushing machine can be started according to the quantity of the sediments in the filtering chamber; a washing device is started for washing the sediment powder in the filtering chamber according to the level of the liquid in the sewage box body; and the sewage lifting device is started for discharging the sediment powder and sewage. According to the invention, a sewage filter and discharge system can be controlled to carry out automatic collecting, filtering, crushing, washing, lifting, discharging in real time according to the need.

Description

technical field [0001] The invention relates to a sewage filtering device and method, in particular to an intelligent filtering and discharging device and method for urban sewage, especially suitable for environmental protection sites where various types of urban sewage and waste water cannot be discharged to indoor or outdoor drainage pipes by themselves. Background technique [0002] Environmental protection is a basic national policy of our country, and the environmental protection industry is one of the new economic growth points of the national economy. The state encourages and supports environmental protection equipment projects. At present, it is necessary to build storage and lifting equipment in places where the self-discharge of sewage and wastewater cannot be realized. Traditional sewage and wastewater storage and lifting equipment are mostly made of reinforced concrete masonry. In this way, not only the construction period is long and the construction is difficul...
