Problems solved by technology

Since the residence time of the dirty soil in the dirty soil concentration tank is only 2 days, and the reproduction cycle of methane bacteria is 4 to 6 days, the anaerobic digestion in the dirty soil concentration tank is not complete, and the concentration of organic matter in the supernatant impurities High, affecting the quality of effluent water
Especially for industrial water treatment with a small amount of water, the return of the supernatant will cause the sewage treatment structures to bear high momentum, seriously affecting the sewage effect

Abstract

The invention discloses a special small pool for cleaning dirty soil. The device comprises a pivot, a soil inlet, hard soil and a wood plate and is characterized in that folding plates are arranged ontwo sides and the upper end of the pivot, the upper end of the hard soil is provided with the soil inlet, the upper end of the hard soil is provided with the wood plate, the upper end of the wood plate is provided with a silt remover, one end of the pivot is provided with a small dam, and the other end of the pivot is provided with a residue chamber. According to the invention, mud particles enter through the soil inlet and are attached with small bubbles to float to a water surface, then small mud blocks are scraped into small pipes by a desilting machine, dirty soil water flows out from thebottom of the pool, so that the sedimentation efficiency of soil in supernatant water is improved, the sedimentation efficiency is improved, the impact force of a sewage treatment process is reduced,the service life of a concentration tank is prolonged, most of hard soil is adopted, steel bars and higher-price hard soil are saved, and the small pool has the characteristic of saving constructioninvestment capital and cost. The calculation work is simplified, and the work period is shortened.

Description

【Technical field】 [0001] The invention relates to an environmental protection device, in particular to a special small pool for cleaning dirty soil. 【Background technique】 [0002] It is generally a round or square pool, and the water content drops from 99.2% to 99.5% to 96% to 98%. The purpose of thickening is to reduce the volume of dirty soil for subsequent processing. According to the working mode, there are continuous type and intermittent type. The vertical flow pool adopts the gravity mud discharge method, which is suitable for places with a small amount of dirty mud. The radial flow pool adopts mechanical mud discharge method, and installs rotating grids to strengthen the mud-water separation process, which is suitable for places with a large amount of dirty mud. The hydraulic retention time of the concentration tank is 8-6 hours. [0003] Dirty soil concentration tank During the treatment of dirty soil in the dirty soil concentration tank, the dirty soil is in a...
