Problems solved by technology

[0002] At present, the sewage pretreatment process basically includes sand settling, sedimentation, oil separation, and air flotation. The conventional pretreatment process has a long residence time, many intermediate links, and the sewage is easily corrupted. The content of suspended solids and dissolved pollutants in the sewage is doubled or several times increased, which causes great difficulty in the subsequent process links and also increases significantly. sewage treatment cost

Abstract

The invention discloses automatic slag scraping and oil collecting slag, oil, sludge and sewage four-phase separation equipment, which comprises a shell (1), an oil collector (2) and an automatic slag scraping device (3), wherein a first partition plate and a second partition plate are arranged in the shell; the shell is divided into an intermediate basin (6), an oil separation sedimentation basin (7) and a slag storage tank (8); the upper end of the intermediate basin is communicated with the upper end of the oil separation sedimentation basin; the oil collector is fixedly arranged on the top of the oil separation sedimentation basin; the top end of the slag storage tank is fixedly provided with a water inlet basin (10); the bottom of the water inlet basin (10) is communicated with the top of the oil separation sedimentation basin (7) through a water inlet (11); the automatic slag scraping device is arranged in the water inlet basin; the water inlet basin is provided with a water inlet pipe (17); the bottom of the intermediate basin (6) is provided with a water outlet pipe (18); and the bottom of the oil separation sedimentation basin (7) is provided with a dredge pipe (19). According to the device, water quality stabilization of the sewage is realized by performing instantaneous separation on slag, oil, sludge and sewage in four phases, so that the sewage treatment cost is reduced.

Description

technical field [0001] The invention relates to a pretreatment device for four-phase separation of residue, sludge and water of sewage, especially for four-phase residue, sludge and water of sewage with high oil content, high content of easily broken suspended matter, and perishable sewage (such as kitchen garbage leachate). Separate pretreatment equipment. Background technique [0002] At present, the sewage pretreatment process basically includes sand settling, sedimentation, oil separation, and air flotation. The conventional pretreatment process has a long residence time, many intermediate links, and the sewage is easily corrupted. The content of suspended solids and dissolved pollutants in the sewage is doubled or several times increased, which causes great difficulty in the subsequent process links and also increases significantly. sewage treatment costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an...
