Problems solved by technology

[0003] There are chemical methods, flocculant methods, bioreactor methods, membrane filtration methods, etc. for the purification of sewage, but some of the above sewage purification methods require huge treatment equipment, some have a long treatment cycle, and some methods even have ecological problems. Risk or secondary pollution to the environment, neither can meet the current needs of sewage treatment

Embodiment 1

[0016] The present embodiment provides a preparation method of a sewage purifying agent, comprising 75 parts of poly-3-hydroxybutyrate, 4 parts of mannose erythritol fat, 34 parts of zeolite powder, 25 parts of alkyl glycosides, 20 parts of maslinic acid, 12 parts of diatomaceous earth are put into a grinder, and the slurry is ground to a particle size of 0.4 micron; wherein, the mass ratio of the raw material mixture: ethanol: glycerol monostearate dispersant is 57:42.6:1.4; the obtained slurry The material passes through a 600-mesh sieve, and then is pumped into a preheated centrifugal spray granulator through a peristaltic pump for granulation and drying to obtain a sewage purifying agent.

Embodiment 2

[0018] The present embodiment provides a kind of preparation method of sewage purification agent, 90 parts of poly(3-hydroxybutyrate-3-hydroxyvalerate), 15 parts of mannose erythritol fat, 45 parts of zeolite powder, alkyl 20 parts of glycosides, 32 parts of maslinic acid, and 5 parts of diatomaceous earth are put into a grinder, and the slurry is ground to a particle size of 0.4 microns; wherein, the mass ratio of raw material mixture: ethanol: glycerol monostearate dispersant is 57 : 42.6: 1.4; Pass the obtained slurry through a 600-mesh sieve, and then pump it into a preheated centrifugal spray granulator through a peristaltic pump for granulation and drying to obtain a sewage purifying agent.

Embodiment 3

[0020] The difference between the third embodiment and the first embodiment is that 12 parts of polybutylene succinate are added to the raw material. Other parts are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the field of sewage purification, and particularly discloses a sewage purifying agent. The sewage purifying agent comprises polyhydroxyalkanoate, mannosylerythrutol lipid, zeolite powder, alkyl glycoside, maslinic acid and diatomaceous earth. A method for preparing the sewage purifying agent includes placing raw materials, ethyl alcohol and glyceryl monostearate dispersingagents into a grinder according to proportions and grinding slurry until slurry with the particle sizes of 0.4-0.5 micrometer is obtained; sieving the obtained slurry via 600-mesh sieves, then pumping the slurry into a preheated centrifugal spray granulator by the aid of peristaltic pumps and carrying out granulating and drying on the slurry to obtain the sewage purifying agent. The sewage purifying agent and the method have the advantages that the sewage purifying agent is mainly prepared from degradable materials and can be slowly degraded while sewage is purified, microbial active agents can be simultaneously released, accordingly, the microbial active agents can have long-term purification functions, and good effects of treating diversified pollutants in the sewage can be realized.

Description

technical field [0001] The invention relates to the field of sewage purification, and specifically discloses a sewage purification agent and a preparation method thereof. Background technique [0002] The odor phenomenon of the water body is the result of anaerobic decomposition of organic matter in the water body. The organic matter consumes a large amount of oxygen during the anaerobic decomposition process, causing the water body to lack oxygen, causing anaerobic microorganisms to multiply and decompose to produce ammonia, hydrogen sulfide, etc. to escape the water surface. , and the lack of oxygen in the water body inhibits the growth and reproduction of beneficial microorganisms, aquatic animals and plants, greatly weakens the aerobic effect of microorganisms, and at the same time leads to the reduction of heavy metals such as iron and manganese in the water, and forms ferrous sulfide with sulfur in the water, making the water appear black. [0003] There are chemical m...
