A kind of sewage treatment equipment used in environmental protection engineering

Abstract

The invention discloses sewage treatment equipment used in environmental protection projects. It includes a housing with a filter screen inside, an opening at the bottom, a matching bottom cover at the opening, a water inlet pipe at the top of the housing, and a water outlet pipe at the bottom of the bottom cover. Both sides are provided with accommodation grooves, and both sides of the top of the bottom cover are connected with connection plates matching the accommodation grooves. The top of the connection plate is provided with a bar-shaped groove, and a compression spring is arranged inside the bar-shaped groove. The other end of the compression spring Both are connected with the bottom of the holding tank, the bottom of the holding tank is provided with an electromagnet, the bottom of the bottom cover is connected with the first cylinder, the piston rod of the first cylinder is connected with the first plate, and one end of the first plate is connected with the second Two plates, the second plate is connected to a horizontally arranged second cylinder on the side away from the housing, and a scraper is connected to the piston rod, and the scraper is located on the outer side of the housing. It makes it possible to remove impurities accumulated at its bottom, ensuring the treatment effect on sewage.

Description

Technical field [0001] The present invention relates to sewage treatment equipment, in particular a sewage treatment equipment for environmental protection engineering. Background [0002] Sewage treatment equipment is an industrial equipment that can effectively treat domestic sewage and industrial wastewater in urban areas, avoiding sewage and pollutants directly flowing into the water, which is of great significance for improving the ecological environment, improving the quality of the city and promoting economic development.
