Recirculation type wastewater treatment recycling system

Abstract

The invention relates to a recirculation type wastewater treatment recycling system. The recirculation type wastewater treatment recycling system comprises the following main steps: after a water quality analyzer detects that the water quality at an outlet of an electric field water treater reaches a set index, a controller starts to open an electrically operated valve on a three-way connecting pipe, which is closed previously, meanwhile, an electrically operated valve on a two-way connecting pipe, which is opened previously, is closed, and water conforming to the set index is conveyed into a purified water storage tank; and b. after the water quality analyzer detects that the water quality at an outlet of an electric field water treater does not conform to a set index, the controller firstly starts to close the electrically operated valve on the three-way connecting pipe, which is opened previously, meanwhile, the electrically operated valve on the two-way connecting pipe, which is closed previously, is opened, and water which does not conform to the set index is conveyed into a wastewater stirring tank and is recycled and treated, thus realizing the recirculation and treatment of the wastewater which does not conform to the set index, and the technical problem that wastewater which does reach the set index is taken as purified water to be stored is solved. The recirculation type wastewater treatment recycling system has the beneficial effect of being capable of reliably supplying purified water conforming to the set index.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a recirculating waste water treatment and recycling system, which belongs to the technical field of waste water treatment. Background technique [0002] The comprehensive prevention and control of waste water pollution has attracted the attention of all countries in the world. Improving waste water treatment technology, improving treatment efficiency, reducing costs and energy consumption are still important research contents. The most effective way to solve water waste pollution is to comprehensively consider water resources planning, water body use, and develop regional water waste pollution prevention and control. At present, most domestic waste water treatment equipment is aimed at large state-owned enterprises, with huge equipment and complicated systems. Enterprises, because the investment and operation and maintenance costs of wastewater treatment equipment are very high, wastew...

Problems solved by technology

However, the use of chemical methods often leads to secondary waste 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 wastewater has become a
