Embodiment Construction

[0025] see figure 1 , figure 1 It is a sewage treatment system structural diagram of the present invention, a sewage treatment method, and its operation method is as follows:

[0026] Step 100: After the sewage is filtered by the first filter screen 1, it flows into the sewage collection tank 2, and the sewage in the sewage collection tank 2 is pumped by the first water pump 3 at a rate of 6m 3 The / h flow is pumped into the iron reduction pool, and in the reduction pool 4, the sewage reduced by the iron reduction pool 4 passes through the acid-base neutralization pool 5;

[0027] The first filter 1 can effectively filter suspended solids with a diameter ≥ 25 μm, including metal compound particles and microbial composite particles.

[0028] Step 200: Put slaked lime into the acid-base neutralization pool 5, the amount of slaked lime can neutralize the pH value of the sewage to 6-7; then filter through the second filter 6 to reach the MRM The molecular resonance cell 7 was l...

Abstract

The invention provides a sewage treatment method. The sewage treatment method comprises the following steps of filtering sewage by a first filter screen, reducing the filtered sewage by an iron reduction tank, carrying out acid-base neutralization by an acid-base neutralization tank, carrying out MRM molecular resonance, carrying out biodegradation purification, and standing for 24 hours in an after-treatment tank. The sewage treatment method realizes zero discharge of sewage. The sewage treatment method has a low cost, can be operated simply, does not adopt any chemical reagents in after-treatment, does not produce secondary pollution on the environment, and solves the problem that heavy metals and microbes in specialized laboratory sewage produced by the existing scientific research institutions and hospitals pollute and damage the environment.

Description

【Technical field】 [0001] The invention specifically relates to a sewage treatment method. 【Background technique】 [0002] At present, heavy metals, microorganisms and other pollutants in the sewage of scientific research institutions, hospitals and other professional laboratories have seriously polluted and damaged the environment, and the existing sewage treatment methods generally include physical and chemical treatment methods, physical sewage treatment methods For example, use fences and sedimentation tanks to separate solid matter and suspended matter in sewage. However, purely physical sewage treatment can only carry out preliminary treatment of sewage, and cannot decompose organic substances in sewage. Chemical sewage treatment methods, such as ion exchange, chemical agents such as bleach, etc., remove suspended particles, organic substances, and metal ions in water, but they have problems such as relatively high cost, difficult recovery of agents, and secondary poll...
