Novel filtering device for sewage treatment equipment

Abstract

The invention provides a novel filtering device for sewage treatment equipment. The novel filtering device comprises a first filtering device and a second filtering device connected by a pipeline. Thefirst filtering device comprises a first shell, and a first stirrer and an alkali adding tank are arranged above the first housing. A first filter net is also arranged in the first shell, and the first filter net is in the shape of a square shell. The second filtering device includes a second shell. A second stirrer and an acid adding box are installed above the second shell. A second filter netand a third filter net are parallelly arranged in the second shell. Through the multi-layered filtration structure of the novel filtering device, oil pollution and heavy metal ions in acidic wastewater can be effectively removed, the purification effect is better, and the industrial wastewater can be recycled and reused.

Description

technical field [0001] The invention belongs to the field of acid wastewater treatment equipment, and in particular relates to a novel filter device for sewage treatment equipment. Background technique [0002] In today's world, water resources are becoming more and more scarce. If the acidic wastewater produced in industrial production is turned into recyclable water resources after equipment treatment, the significance and benefits will be self-evident. In the existing Among the equipment, the more common treatment equipment generally undergoes neutralization, flocculation, sedimentation, and effluent. If recycled water with better water quality is to be obtained, evaporation, reuse, and clarification are often performed. Although the treatment equipment can play a certain role in the recycling and utilization of wastewater, there are many problems, such as the need to add a large number of new equipment and facilities, occupying a large area, high investment costs, poor t...

[0002] In today's world, water resources are becoming more and more scarce. If the acidic wastewater produced in industrial production is turned into recyclable water resources after equipment treatment, the significance and benefits will be self-evident. In the existing Among the equipment, the more common treatment equipment generally undergoes neutralization, flocculation, sedimentation, and effluent. If recycled water with better water quality is to be obtained, evaporation, reuse, and clarification are often performed. Although the treatment equipment can play a certain role in the recycling and utilization of wastewater, there are many problems, such as the need to add a large number of new equipment and facilities, occupying a large area, high investment costs, poor treatment effect and difficult maintenance. In view of this situation, the present invention proposes a novel filter device for sewage treatment equipment, which can effectively remove oil stains, impurity suspended solids, supersaturated sulfites, sulfates and heavy metals contained in acidic wastewater, and remove waste water Converting to recyclable water resources, simplifying equipment, significantly saving production costs, easy maintenance, saving energy and saving production costs
