Problems solved by technology

Existing exogenous strengthening is mainly divided into three categories, namely metal ion strengthening, coagulant / coagulant strengthening and inert carrier strengthening. However, the above strengthening methods will not only increase the cost, but also fail to solve the long-term The problem of structural instability during operation

Embodiment 1

[0054] The present embodiment has prepared a kind of biological agent for sewage treatment, and the specific process is:

[0055] (1) Preparation of the induced core: After melting and mixing the recovered degradable plastic, it is extruded into a three-dimensional helical structure by granulation. Process such as figure 1 shown. figure 1 Among them, 1 is the induced nucleus with a three-dimensional helical structure, and 2 is the microbial colony aggregate attached to the induced nucleus to grow.

[0056] The length of the induced core of the three-dimensional helical structure is 1-2 mm. Induced nuclei prepared as figure 2 with image 3 shown. figure 2 It is the result of naked eye observation, image 3 It is observed under a microscope. from figure 2 with image 3 It can be seen that the aggregate structure of microbial colony aggregates induced by attachment-induced nuclear growth is relatively compact.

[0057] Among them, degradable plastics are recycled deg...

Embodiment 2

[0065] The present embodiment has prepared a kind of biological agent for sewage treatment, and the specific process is:

[0066] (1) Preparation of the induced core: After melting and mixing the recycled degradable plastic and the catalyst, it is granulated and extruded into a three-dimensional helical structure.

[0067] The length of the induced core of the three-dimensional helical structure is 1-2 mm.

[0068] Among them, the degradable plastics are degradable plastic bags and degradable mulch, and the catalyst is phenylalanine.

[0069] The raw materials for the preparation of the induced nucleus include the following components in parts by weight:

[0070] Biodegradable plastic: 95 parts,

[0071] Catalyst: 5 parts.

[0072] (2) Preparation of sewage treatment biological agents:

[0073] The prepared induced nuclei were placed in the same sewage and reactor as in Example 1 for cultivation.

[0074] After culturing for 42 days, it was observed that the sewage treatm...

Embodiment 3

[0076] The present embodiment has prepared a kind of biological agent for sewage treatment, and the specific process is:

[0077] (1) Preparation of the induced core: After melting and mixing the recycled degradable plastic with catalyst and ore powder, it is granulated and extruded into a three-dimensional helical structure.

[0078] The length of the induced core of the three-dimensional helical structure is 1-2 mm.

[0079] Among them, the degradable plastics are degradable packaging bags and degradable plastic film, the catalyst is phenylalanine, and the mineral powder is calcium powder and pyrite powder. The mass ratio of calcium powder and pyrite powder is 1:4.

[0080] The raw materials for the preparation of the induced nucleus include the following components in parts by weight:

[0081] Biodegradable plastic: 92 parts,

[0082] Catalyst: 5 parts,

[0083] Mineral powder: 3 parts.

[0084] (2) Preparation of sewage treatment biological agents:

[0085] The prepar...

Abstract

The invention provides a sewage treatment biological agent, a preparation method and application thereof. The sewage treatment biological agent disclosed by the embodiment of the invention comprises an induction nucleus, wherein the induction nucleus has good biocompatibility, microbial flora can be attached to the induction nucleus to realize rapid growth, and the sewage treatment biological agent is gradually granulated along with aggregation and growth of the microbial flora on the induction nucleus, so that the sewage treatment biological agent is conveniently used for sewage treatment. According to the invention, a microbial flora grows on the induction nucleus, and the growth process of the microbial flora is a coating growth process which starts from the induction nucleus, gradually expands outwards and takes the induction nucleus as the center; and the microbial flora can secrete extracellular polymeric substances in the growth process, and the extracellular polymeric substances can further promote the granulation process of the sewage treatment biological agent.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment biological preparation and its preparation method and application. Background technique [0002] With the increase of urban population, the problem of urban domestic sewage has become increasingly prominent. The treatment technologies of urban sewage are divided into three categories according to the mechanism of action, one is physical treatment, the other is chemical treatment, and the third is biological treatment. Among them, the physical treatment method separates and recovers the suspended pollutants in the sewage through physical action, and does not change the chemical properties of the pollutants during the treatment process. It mainly includes sieve retention method, gravity separation method and centrifugal separation method. The chemical treatment method separates and recycles the dissolved and colloidal pollutants in the sewa...
