Operation method of a recirculating sewage treatment and recycling system

Abstract

The invention relates to a control method of a recirculation-type sewage treatment recycling system. The control method comprises the following steps: a, when a water quality analyzer detects that the water quality at the electric field water treatment device outlet reaches a set indicator, a controller opens a previously closed electric valve on a three-way connection pipe, and closes a previously open electric valve on a two-way connection pipe, such that water meeting the set indicator is delivered into a clean water storage tank; b, when the water quality analyzer detects that the water quality at the electric field water treatment device outlet does not reach the set indicator, the controller closes the previously open electric valve on the three-way connection pipe, and opens the previously closed valve electric valve on the two-way connection valve, such that disqualified water is delivered into a sewage stirring tank and is subjected to a recirculation treatment. With the system, disqualified sewage is subjected to the recirculation treatment, such that disqualified water is prevented from being stored as clean water, and clean water meeting the set indicator can be reliably supplied.

Description

technical field [0001] The invention relates to a water treatment method, in particular to an operation method of a recirculation type water treatment recycling system, and belongs to the technical field of sewage treatment. Background technique [0002] The comprehensive prevention and control of water pollution has attracted widespread attention from all over the world. Improving sewage treatment technology, improving treatment efficiency, reducing costs and energy consumption are still important research contents. The most effective way to solve water pollution is to comprehensively consider water resources planning, water body use, and develop regional water pollution prevention and control. At present, most domestic sewage treatment equipment is aimed at large state-owned enterprises, with huge equipment and complicated systems. For many small and medium-sized enterprises in the initial stage, Because the investment and operation and maintenance costs of sewage treatmen...

AI Technical Summary

Problems solved by technology

However, the use of chemical methods often brings secondary pollution, and the cost of biological treatment is relatively high, and the subsequent separation of heavy metal ions is also relatively complicated. Therefore, the use of physical methods to recycle sewage has become a research direction.

Most of the existing processors pass the water into the clean water for storage after the sewage is treated once, so that the turbidity of the sewage cannot be recycled. Therefore, the present invention proposes a recirculating water treatment Control method of recycling system
