Problems solved by technology

From the analysis of its structure and operation mode, the design principle of the inclined tube sedimentation tank is adopted, and the surface load is seriously high, resulting in poor water discharge effect.
At the same time, according to the calculation of the pool body in the reaction area, the residence time of the water flow in this area is short, the flow rate is fast, and no mud layer is formed in the stirring area, so the subsequent inclined plate sedimentation and separation are greatly agitated, which affects the degreasing effect

Embodiment 1

[0027] Such as figure 2 As shown, this embodiment includes: a water distribution area, a reaction area, a sedimentation area, and a sludge area. The reaction area is distributed in the water distribution area, the sludge area is distributed at the bottom of the reaction area, and the sedimentation area is distributed at the upper end of the outer periphery of the reaction area. It also includes an outlet triangular weir 4 and a lifting mixer 2, and the lifting mixer 2 is installed across the reaction zone. The reaction zone includes a first reaction zone and a second reaction zone. The first reaction zone and the sludge zone are combined to share one area, and have a conical bottom. A water distribution tank is provided at the bottom of the second reaction zone, and water is introduced into the water distribution tank through the annular water distribution tank 1 . A baffle plate 3 is installed at the outlet triangular weir. First, change the raw water inlet method, from t...

Abstract

The invention relates to a device in the field of wastewater treatment technology and in particular to a novel chemical oil remover. The oil remover comprises a water distribution region, a reaction region, a settlement region and a sludge region, wherein the reaction region is distributed in the water distribution region, the sludge region is distributed at the bottom of the reaction region, and the settlement region is distributed on the upper end of the outer circle of the reaction region. The oil remover also comprises an effluent triangular weir and a lifting stirrer, wherein the lifting stirrer is arranged in and traverses the reaction region. Through changing the design of the device, the invention reduces the surface load of the device, improves effluent effect, lowers flow speed for forming a mud layer and improves oil removal effect.

Description

technical field [0001] The invention relates to equipment in the technical field of wastewater treatment, in particular to a novel chemical degreaser. Background technique [0002] The structural characteristics of the MHCY type chemical degreaser in the prior art. [0003] (1), MHCY type chemical degreaser is mainly composed of three parts: reaction area, sedimentation area and sludge storage area. [0004] (2), MHCY type chemical degreaser is specially designed for treating the oily and oxidized iron scale sewage (turbid ring water) discharged from the continuous casting and rolling workshop of metallurgical enterprises. [0005] (3) Chemical degreasing is to add chemical agents, and after mixed reaction, the suspended solids such as oil and iron scale in the water will be separated by coagulation and flocculation to achieve the purpose of purifying water quality. [0006] (4) There are two kinds of medicaments to be added, which are added separately. The first belongs ...
