The invention relates to an aluminum alloy anodizing line treatment process. The aluminum alloy anodizing line treatment process comprises a functional trough system and water washing trough systems arranged between functional troughs. The functional trough system is arranged along the flow direction of washing water in a manner that an upstream functional trough is compatible with a downstream functional trough, and the water washing trough systems are arranged in an overall phase-reversing in-series-connection manner. According to the aluminum alloy anodizing line treatment process, a mode in which a flowing water washing tank is separately configured for each functional trough in the traditional anodizing line is changed. Since all water washing troughs are connected in series in a phase-reversing manner, the number of the water inlets and outlets is greatly reduced and the water consumption is decreased from 25.0-35.0 tons per ton material to 5.0-6.0 tons per ton material and the water is saved by more than 80%. The treatment process disclosed by the invention has the advantages of low production cost, high efficiency and environmental friendliness and is suitable for industrial application.

The invention belongs to the technical field of chromium residue detoxifying, and discloses a chromium residue detoxifying process. The process comprises the following steps of: performing wet grinding on chromium residue, adding water into the chromium residue to prepare chromium residue slurry; and after being subjected to acid-leaching reduction reaction, performing solid-liquid separation on the chromium residue slurry to obtain a filter cake, namely the detoxified chromium residue. The process is characterized in that: under the condition of not changing the original alkaline environment of the chromium residue, a reducing agent 1 is added into the chromium residue directly, and then the reducing agent and the chromium residue are subjected to wet grinding to form particles with 100 to 300 meshes; and the water is added to prepare the chromium residue slurry with 30 to 45 baume degrees, wherein the reducing agent 1 is sodium sulphide, sodium bisulfide, sodium thiosulfate or sodium pyrosulfite. The process has simpleness, thorough detoxification, no chromium return phenomenon and easy implementation of mass production; and the process prolongs effective reduction reaction time, improves reaction efficiency, saves the using amount of acid during the acid-leaching reduction, and has low processing cost because Cr6+ in the chromium residue is subjected to two times of dissolution and reduction.

Abstract of the Disclosure

A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.
