Sewage treatment and reutilization circulating system

Abstract

The invention discloses a sewage treatment and reutilization circulating system. The sewage treatment and reutilization circulating system comprises a flow collection chamber, a pressurizing device, amulti-grade sewage treatment device, an integrated power control device and a speed-reducing pump, wherein a sewage valve and a circulating valve are arranged at a side edge of the flow collection chamber; a sewage capacity sensor is arranged in the flow collection chamber; the circulating valve is connected with a double-pipe solenoid valve through a sewage circulating pipeline; a flow guide pipe is arranged between the flow collection chamber and the pressurizing device; the pressurizing device is connected with a filtering device; a waste dreg discharging pipe is arranged at the side edgeof the filtering device; the multi-grade sewage treatment device is connected with the filtering device. The sewage treatment and reutilization circulating system disclosed by the invention has the beneficial effects that sewage can be subjected to filtering, multi-grade purification and sterilization treatment, the sewage purification efficiency is high and the purification quality is high; meanwhile, whether purified sewage quality accords with standards or not can be detected; when the purified sewage quality does not accord with purification standards, circulating treatment is carried outand purification quality of treated water is ensured.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, and the invention relates to a recycling system for sewage treatment and reuse. Background technique [0002] Sewage refers to polluted water, including domestic sewage, chemical sewage, commercial sewage, agricultural sewage, etc. The main pollutants in water include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0003] Water is the cornerstone of biological survival, so the harm of water pollution to biological can be imagined. With the increasing emphasis on environmental protection issues in our country, water pollution has also attracted more and more attention, and various equipment for water treatment emerge in an endless stream. Dispose of waste water such as factory waste water and domestic waste water after treatment to reduce the damage of sewage to the natural world. However, these sewage treatment equipment on the market generally o...

[0003] Water is the cornerstone of biological survival, so the harm of water pollution to organisms can be imagined. With the increasing emphasis on environmental protection in our country, water pollution has also attracted more and more attention. Various equipment for water treatment emerge in endlessly. Wastewater such as factory wastewater and domestic wastewater is treated and discharged to reduce the damage of sewage to the natural world. However, these sewage treatment equipment on the market generally only have one-way treatment functions, and the general applicability is poor. It is difficult to ensure the efficiency of sewage treatment, and the degree of integration is poor
