Domestic sewage treatment system utilizing microorganisms

Abstract

The invention relates to the field of sewage treatment, in particular to a domestic sewage treatment system utilizing microorganisms, the domestic sewage treatment system comprises a sewage treatmenttank, a filler support, a driving device and a transmission device, and is characterized in that the sewage treatment tank is defined by two cement side plates and two cement front plates and is usedfor containing domestic sewage; the filler support is horizontally mounted at the top of the sewage treatment tank and is used for hanging a sewage treatment filler; the driving device is used for outputting power, the transmission device is used for transmitting power, and the driving device is matched with the transmission device to enable the filler support to ascend and descend in the verticaldirection. The domestic sewage treatment system has at least one of the following beneficial technical effects: the domestic sewage treatment system can adapt to sewage treatment requirements of various different liquid level heights; the opening of each sewage treatment tank can be ensured by a sewage treatment plant in the light and high-temperature season of sewage treatment; and the total cost of reculturing the microorganisms in the sewage treatment plant can be saved.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, it relates to a domestic sewage treatment system using microorganisms. Background technique [0002] Domestic sewage is the sewage generated in people's daily life. People need to treat domestic sewage before it can be discharged into rivers. [0003] There are various ways to treat domestic sewage, mainly in three forms: physical treatment, chemical treatment and biological treatment. Physical treatment refers to the purification of domestic sewage through gravity separation, sieve retention, gas-liquid exchange, centrifugal separation, and high-gradient magnetic separation. Chemical treatment is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer. The treatment methods based on the chemical reaction produced by dosing agents include coa...

Problems solved by technology

When the amount of sewage treatment decreases, the sewage treatment plant needs to suspend and close a certain amount of sewage treatment tanks. There are many reasons for the reduction of sewage treatment volume. There is a situation that the amount of domestic sewage in summer and autumn is higher than that in winter and spring, and the suspension of the use of sewage treatment tanks will cause irreversible damage to the colony environment formed on the filler. Every time a sewage treatment tank is re-opened , all need to be re-cultivated to form such a colony environment

Since some colonies that can efficiently treat sewage are difficult to cultivate, repeated re-cultivation of colonies will greatly increase the treatment cost of sewage treatment plants
