Abstract

An environment-friendly chemical sewage treatment device comprises a sewage pool with a water inlet and a water outlet and more than two filter screens. Multiple hollow cones with downward openings are distributed on the filter screens. The filter screens are arranged in the sewage pool at intervals up and down; the hollow cone on the lower filter screen is correspondingly inserted into the innercavity of the upper hollow cone, and the lower hollow cone and the inner wall of the upper corresponding hollow cone are arranged at intervals, so that an oil storage cavity is formed in the interval.Wastewater enters the interval of the filter screen through the water inlet, oil stains in the wastewater enter and are kept in the oil storage cavity under the action of buoyancy, sewage flows backwards from the position below the oil stains, the oil stains in the wastewater are gradually collected by the oil storage cavity in the filter screen along with flowing of the wastewater, and the sewage and the oil stains are separated. According to the sewage treatment device, a layered filtering method is adopted, waiting is not needed during wastewater treatment, oil stains can be rapidly treated, and sewage treated by the sewage treatment device directly flows into a next-stage system. The structure is simple, and the sewage treatment efficiency is improved from two dimensions of time and space.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an environment-friendly chemical sewage treatment device. Background technique [0002] Wastewater in the chemical industry often includes sewage, oil and sludge. Pollutants are dissolved in the sewage, causing great harm to the environment. There are many types of wastewater treatment in the prior art. For example, the application number CN201810657195.5 discloses a The oil pollution separation and sedimentation tank includes the first water storage tank, the second water storage tank and the third water storage tank connected in sequence; the side of the second water storage tank connected to the first water storage tank is higher than the second water storage tank and one side of the third reservoir; the side wall connected between the second reservoir and the first reservoir is provided with some filter holes, and some of the filter holes are located near the top of the first ...
