Environment-friendly sewage pretreatment device based on rotary centripetal force

Abstract

The invention provides an environment-friendly sewage pretreatment device based on rotary centripetal force, and relates to the technical field of sewage treatment. The environment-friendly sewage pretreatment device based on the rotary centripetal force comprises a tank body, wherein a partition plate is fixedly mounted at the top of the tank body, an adhesive is poured above the partition platein the tank body, a feeding port is fixedly connected to the top of the tank body, a cylinder is rotatably connected to the interior of the tank body, a motor is in transmission connection to the topend of the cylinder, and a feeding hole is formed in the periphery of the top of the cylinder. According to the environment-friendly sewage pretreatment device based on the rotary centripetal force, formed floccules can enter the sewage collecting barrel to be collected and regularly extracted by utilizing the centripetal force during sewage rotational flow, so that the use of a filter screen is avoided, the normal flow of sewage is not influenced, and the treatment efficiency is improved; the phenomena of insufficient pretreatment and secondary pollution caused by too much or too little use of the adhesive are avoided, and the device is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environmentally friendly sewage pretreatment device based on rotational centripetal force. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. It is an important process to realize the recycling of water resources and environmental protection. In the pretreatment stage of sewage, the main cleaning The most important thing is the fixed impurities and fine particles in the sewage. In order to facilitate cleaning, adhesives are added to the sewage to form flocs. However, the traditional sewage pretreatment devices filter and clean the impurities through the filter screen. During the process of use, the filter screen will be gradually clogged, so that the sewage cannot normally flow into the treatment device of the next stage, which reduces the eff...

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. It is an important process to realize the recycling of water resources and environmental protection. In the pretreatment stage of sewage, the main cleaning The most important thing is the fixed impurities and fine particles in the sewage. In order to facilitate cleaning, adhesives are added to the sewage to form flocs. However, the traditional sewage pretreatment devices filter and clean the impurities through the filter screen. During the process of use, the filter screen will be gradually clogged, so that the sewage cannot normally flow into the treatment device of the next stage, which reduces the efficiency of treatment, and when the traditional sewage pretreatment device adds adhesives, it directly binds the In the continuous sewage treatment, not only the mixing effect is poor, but also the amount of adhesive cannot be adjusted conveniently, and it is easy to use too much or too little, which leads to insufficient pretreatment and secondary The phenomenon of secondary pollution does not conform to the concept of environmental protection
